Had my first experience of a MapAThon last night at Hogan Lovells. Mapping areas of South Sudan. Really excellent.

Validation feedback can provide important social affirmation

Posted by dekstop on 8 February 2017 in English (English)

After my talk at State of the Map in Brussels, Nick Allen asked: are newcomers to HOT more likely to be retained if we give them positive validation feedback? And conversely, do we discourage them if we invalidate their work? I had no answer at the time, in part because many validation interactions are not public. However, I agreed with his observation that these are likely important early encounters, and that we should make an effort to understand them better. In particular, we should be able to provide basic guidance to validators, based on empirical observations of past outcomes. What are the elements of impactful feedback?

I spoke to Tyler Radford about these concerns that same day, and within a few days we signed an agreement which gives me permission to look at the data, provided I do not share any personal information. The full write-up of the resulting research is now going through peer review, and I will share it when that's done. In the meantime, I thought I should publish the most important findings.

Manually labelling 1,300 messages...

I spent the next months diving into the data, reviewing 1,300 validation messages that have been sent to first-time mappers. I labelled the content of each message using models from motivational psychology, and feedback in education settings. For now I'll skip a detailed discussion of the details, but feel free to ask questions in the comments.

I assessed the impact of different kinds of newcomer feedback:

  • Positive performance feedback: messages including comments like "good job", "great work", "looks good", ...
  • Negative performance feedback: "doesn’t look complete", "missing tags", "needs improvement", ...
  • Corrective feedback: guidance about specific improvements to improve future work, including links to documentation.
  • Verbal rewards: messages containing positive performance feedback, gratitude ("thanks!"), or encouragement ("keep mapping").

Here's a chart of the frequency of each type of feedback across the messages I labelled:

Use of feedback techniques in validation messages

To measure the effect of these feedback types, I collected the contributions for each newcomer over a 45-day period after their initial edit, and labelled the content of the first feedback message they received during this time. I then observed for how many days they remained active, or whether they dropped out (as measured with an additional 45-day period of inactivity). I then used a Cox proportional hazards model to explain the retention rates we observed, based on a set of features and control variables. This is comparable to a regression analysis, but specifically intended to model participant "survival". In the context of this study, the term `hazard' is a synonym for the risk of abandoning HOT participation. A hazards model yields a hazard rate (or rate of risk) for each contributing factor, denoting the relative increase in hazard when a particular feature is present. For example, a hazard rate of 2.0 means that the person is twice as likely to stop contributing within the observation period, compared to the average. Conversely, a low hazard rate of 0.5 means they are twice as likely to still remain active at the end of the observation period.

Social affirmation matters: someone else cares

Maybe most importantly, I found that the feedback can be an important source of social affirmation, which in turn can improve newcomer retention. This effect is most clear among newcomers who contributed comparatively less on their first day (mapping less that the median of 75 minutes), possibly because they have low intrinsic motivation or self-efficacy. Among these, people who received verbal rewards in their first feedback message were significantly more likely to keep mapping, at a reduction of the hazard rate to 80%. In comparison, newcomers who already start with a high degree of engagement may not require such affective-supportive feedback to remain engaged.

This makes sense when you consider the wider context. The process of contributing to HOT online can be considered a depersonalised form of interaction: it is often focused on the task, rather than the learner. In the absence of other prominent social cues, small phrases of support may have a large effect. In the case of validation feedback, it's likely also important that this is not simply an automated message. Instead, someone else looked over your work and then took the effort to write some kind words.

To my surprise, negative performance feedback in itself is not necessarily discouraging to newcomers: while it may demotivate some individuals, in aggregate across all newcomers there was no significant effect on retention. This includes instances of invalidated tasks, and negative performance feedback such as "your buildings are all untagged". This may be because the feedback is private: people don't have to be concerned about the impact on their reputation, and can focus on improving their skills. In communities like Wikipedia where feedback tends to be public (in the form of comments or reversions), it was found that negative feedback can harm newcomer retention. It's also worth mentioning that even "negative" feedback in HOT still tends to be polite and constructive: HOT validators are generally a very polite bunch, based on the messages I've seen. They might simply point out that you forgot to square your buildings.

The timing of feedback matters: feedback that is sent a week after a contribution is significantly less likely to still have a motivational impact. In comparison, feedback that is sent within 28 hours or less (the median delay) yielded a reduction of the hazard rate to 80%. Any additional day of delay increased the hazard rate.

I now believe that this places validators at the core of the HOT community: for many contributors who can't attend a mapathon, and who haven't subscribed to the mailing list or joined IRC, validation feedback is their first experience of a social encounter. For a number of reasons, the current iteration of the tasking manager doesn't easily support such interactions (maybe a topic for a future post); but I'm looking forward to the next iteration, which is already in planning. As I've learned through discussions, the validator community already has some great ideas about improving it even further.

The fine print

First off, this is an observational study, which comes with some constraints: we can identify links between validation styles and outcomes, and control for confounding factors through careful model design, which gives us some confidence in the findings. However, we would have to run actual experiments to confirm each link.

The models behind these findings account for a number of confounding factors. For example, I consider each newcomer's initial contribution activity: were they already enthusiastic contributors to begin with? I also look at the particular project they start with: did they join during a disaster campaign, possibly in a wave of public interest? Such newcomers tend to not stick around for long.

And my usual caveat applies: I assessed the impact on contributor activity and retention, but not on contribution quality. In part because I still haven't found a good approach to assessing contribution quality at this scale: there is no ground truth available for comparisons, and contribution practices are diverse and often specific to the geographic/thematic context. Developing methods to assess data quality at this scale is a research project in its own right.

This is certainly not the final word on validation feedback, and I expect many others will add to this (maybe in the comments)? But it can hopefully serve as one contribution to our growing body of knowledge about how best to support our maturing community.

Highways & Byways: Roman & Drovers’ Roads in Ware, Hertfordshire

Posted by alexkemp on 7 February 2017 in English (English)

Most of the places that I've mapped across the last 10 months have been ~1930s with the occasional Victorian terraces (1880s). The topic today arose from looking at the deeds of a 1906 house but, as the first words of the first line below makes clear, has far more ancient origins:–

  • In 13th Century England the following two, apparently contradictory, statements are both true:–
  1. Most people were born, lived & died within the same 5 mile (8km) radius.
  2. England was covered with a network of streets & roads each many hundreds of miles long; further, these streets & roads were continually thronged with people travelling long distances upon them.

“Streets” here refers mostly to the well-known Roman Roads. During research for this Diary entry I was surprised to discover that Ware was positioned upon Ermine Street, a Roman Road that stretches from London to York & crosses the Humber close to my birth town of Hull. For reference, here is a map of Roman Roads:–

Roman roads in England

I've travelled Ermine Street a lot. My personal research suggests that, whilst the Roman Roads may have been occasionally used in Medieval times for long journeys, the local people had their own network of paths (nothing to do with the Romans) and which they preferred. So, the A15 runs north from Lincoln as straight as an arrow along Ermine Street, but it is perfectly clear that the locals preferred the B1398 which takes the same general direction but follows each field boundary & every circumlocution that it can find.

Well, that's the Highways covered, but now the Byways.

“Roads” here refers to the less-well-known Drovers’ Roads. In order to spot one of these you will need to spot something like the following (hint: it is the words Public Byway that is the secret signal):–

Public Byway sign

When I were a lad the black ‘n’ white TV would often show black ‘n’ white cowboy movies. Frequently, these movies would involve a bunch of cowboys driving hundreds or thousands of cattle many hundreds of miles across the plains of America. Amazingly, exactly the same business happened in the UK, and across the same distances, and hundreds of years before the USA. Perhaps the main difference was that (at least in the movies) in the USA it was always cattle, but in the UK as well as oxen & cattle, there were also sheep, geese, turkey, pig, and horse drives.

The same routes were used every time & in places became worn down by the repetition (it is thought that some drove routes may have been used since prehistoric times). Many were much wider than other roads, at least 40 feet wide (12m) and up to 90 feet (27m) wide on occasion.

It seems that Ware had lots of Drovers’ Roads (look at ‘Musley Lane’) and, of course, pubs such as The Standard (now gone) to cater to the Drovers. However, as towns began to expand, the desire to allow a 12m road to remain diminished. In addition, such roads would have been anathema during the Enclosures of 1760 & later (aka legal theft). Nevertheless they do remain, much diminished in size and length, as Public Byways (and just to show how much of this info is new, notice that that wiki-link has zero mention of Drovers’ Roads).

So, how did I discover this?

One of the houses on Hampden Hill, Ware had a house-name & the lady of the house was available to give permission for me to photograph it. I asked if she knew the start_date which led to a short conversation, and she invited me in to look at the house deeds. These turned out to be a stack of vellum sheets (parchment — damn expensive stuff) more than an inch (2.54cm) thick, each covered with beautiful Copperplate script (the lady's Solicitor gave her these documents on completion of purchase; they used to be held by Land Registry but were all digitised some years ago & are now routinely returned to the house owner). A builder in 1904 bought Plot 27 (and also later Plot 28) for £30 GBP ($37 USD, €35 Euro) from The Commonwealth Estate (land formerly owned by Cambridge University). The builder was tied up with someone else, and it was all very complicated (I know already that most folks at the time rented — as a common example — on a 100 year lease rather than owned their house). It seems that the house was built on the two plots sometime after 1906.

The above was extremely interesting, but my attention was drawn by something at the extreme top-left of the site drawing (I wish now that I had photographed it): passing across the corner of the plot of what is now 17 Hampden Hill was a wide roadway (wrong number! - see below), and written on the drawing was “Old Drovers’ Road”. North of the plot for Hampden Hill is King George’s Field Recreation Ground; the Old Drovers’ Roadway came up from the left of all the plots for Hampden Hill, passed across the top-left of that plot, and continued across the southern-base of King George’s Field to the right. I was intrigued; what on earth was a Drovers’ Road?

Later in my mapping I had a chat with the son of the owner for the house on the corner of Hampden Hill and Hampden Hill Close (he came up to me with one of those “what on earth do you think you are doing?” questions whilst I was photographing the street-sign). The house turns out to have a Medieval hedge that runs along Hampden Hill Close.

So, that old drover's road starts in modern times as a Public Byway sign (9 miles) (14km) on Musley Lane and travels along a footpath which terminates at the end of Hampden Hill Close. The Byway signs finish at this point, but it definitely continues along Hampden Hill Close (it's a cul-de-sac), then Hampden Hill to the top-centre & the opening into King George’s Field. It then travels behind the Jolly Bargeman & will still have another 8 miles to go!

Coda 1: This Drovers Road on OS 1.25k Historic (OSM-Limited)

(below is a single tile obtained via JOSM; these tiles seem not to want to sit together on the same line; I tried using HTML <table> tags to stitch some tiles together to show a better view, but this OSM Markdown did not want to know).

Old Drovers’ Road, Ware

The vertical road above is Hampden Hill up to the 1906 house; the modern road continues up and turns a right-angle to the right. The grey road that crosses above it (marked elsewhere as ‘FP’, although other footpaths are shown as dotted black lines) is the Old Drovers’ Road. It begins on Musley Lane exactly where the modern signpost is and follows the modern Public Byway very closely indeed. Hampden Hill Close is exactly on it's southern border almost all the way to Hampden Hill and it actually passes through numbers 11 & 9 Hampden Hill rather than 17 as I said before. It also leaves the modern Hampden Hill exactly at the point where the modern King George’s Field footpath begins & even follows the north-east footpath through the recreation ground. It's quite uncanny. That modern footpath turns sharply to the right & emerges on Cromwell Road, whereas the Old Drovers’ Road continues straight ahead & behind the pub, running parallel, but 100 yards or so to the west, of Cromwell Road.

This ancient road then gets lost on the modern map, although small traces are left behind. Tracing it to the north we see that Dark Lane (a bridle path) lies on the route, as does an un-named bridle route trace part of a spur that goes east via close to the join of the modern Woodley Road with Cromwell Road.

It is the fact that ancient ways continue to influence folks today that causes me to be fascinated by this stuff. One little connected story to finish:–

I was visiting my grand-kids in Ware last year when they said that they were going to give Buddy (their yappy little dog) a walk, and would I like to come? We ended up in the King George’s Field park, then into Hampden Hill and, sure ’nuff, down the Public Byway on to Musley Lane, then home. All these centuries later, folks are still walking those tracks.

Coda 2: Yet More Intelligence

In 1904 the Drovers' Road was the only road that existed to the East of Ware (in JOSM, use the NLS Bartholomew 1897-1907 Imagery). It travelled from Fanhams Hall Road in the north to Musley Lane in the south. By the 1930s a number of things had happened (the NLS OS 1.25k 1st Series 1937-1961 imagery is useful here):–

  1. The 1920s & 1930s building spurt that followed WW1 had begun to extend from Victorian New Road/Musley Hill eastwards into the Commonwealth Estate.
  2. Such building stopped at the Drovers' Road, in the same way as the earlier Hampden Hill had stopped at that road.
  3. The Drovers' Road fell into disuse. The far-northern end was retained as was the far-southern end, but the middle section stopped being a ‘road’ & became a ‘footpath’. As development continued & memories faded or died, even the footpath became a distant story buried within house back-gardens or behind the pub or upon a piece of parchment.

Via an East Herts Council map (up-to-date map supplied by the OS; have patience, it is dog slow) I found that the southern footpath is also called “Dark Lane”, which suggests that the entire section of road may have been called that. I've not spotted any signposts with that name on the path, but will ask around at my next visit. If anyone says yes I will name it!

PS

Experimenting with Dingus I was able to build a Markdown <table> that made a decent fist of stitching OS 1.25k Historic tiles together to show the route of that Old Drovers' Road. However, then found that this Diary's version of Markdown did not support it. Bugger.

Mapping Errors in Guatemala and Honduras

Posted by Sunfishtommy on 7 February 2017 in English (English)

I am writing this because i am not sure who would be best to talk to. I map heavily in latin America and while looking around recently using the ITO maps I realized that a lot of edits had been made in a short amount of time in Guatemala and Honduras. (http://product.itoworld.com/map/129?lon=-88.44987&lat=15.72091&zoom=7)

It seemed like an import which I thought was unusual in Central America as there is usually not that much data to rely upon. Upon Closer look I realized that it was actually a huge mapping project with HOT OSM Like this one (http://tasks.hotosm.org/project/2461#).

But when I looked at the data I realized that the data is incredibly rough, incomplete with often times incorrect geometry and attributes. This area here (http://www.openstreetmap.org/#map=12/15.6948/-90.3553) and here (http://www.openstreetmap.org/#map=12/15.8144/-85.4953) help to illustrate the problem. Random sections of road are marked as high priority. Upon closer examination you will see that often times the geometry of these roads is also extremely rough, with many roads missing and the ones that are mapped seem to be have done at random.

On HOT osm the areas are almost completely marked finished with no reviews. as can be seen her on project 9, 10, 11, 12, 13.

I am wondering what can be done to rectify this situation, and what can be done to prevent this in the future. It is very confusing to have this much low quality data being imputed into the map in mass like this. And to have this much low quality data dumped into the map lowers the quality of the data overall.

What can we do to fix this?

О нас

  • Немецкое сообщество в этом месте написало про свой подкаст (автоматический перевод), который "скорее жив чем мёртв". Однако, нашей команде тоже есть, чем похвалиться - каждый четверг выборочные новости Еженедельника ОСМ (и не только) озвучиваются в прямом эфире и записи затем выкладываются (уже три!). Респекты Sadless74 ;-)

Картографирование

  • Chetan из Mapbox пишет про этот изумительный стиль OSMIC для JOSM - плагин, позволяющий во время редактирования OpenStreetMap видеть значки всех POI.

  • AkuAnakTimur из Малазии спрашивал давным-давно на форуме, существует ли альтернатива снимкам Bing, т.к. огромные территории не покрыты. Наконец-то пришёл ответ по твиттеру - грядёт обновление снимков.

  • Юзер Wille из Бразилии сделал доступными GPS-треки, собранные бразильским Агентством по охране окружающей среды. Для того чтобы использовать данные в ImproveOSM, Martijn van Exel подкрутил алгоритм для распознавания отсутствующих дорог. Теперь ImproveOSM подскажет, где в Бразилии есть грунтовки. Пользоваться ImproveOSM можно не только в редакторе iD. Существует и плагин для JOSM.

  • В твите Brundritt сообщается, что Bing Maps обновляют у себя спутниковые снимки. Согласно информации процесс должен быть завершён в течение нескольких месяцев.

  • В списке рассылки talk-GB, Эндрю Хейн (Andrew Hain) сообщает, что на юго-западе Лондона (столица Великобритании) некий "картограф" надобавлял имён в полигоны landuse=residential и landuse=commercial. Этот картограф не отвечает на комментарии, которые Хейн оставил к пакетам правок, пытаясь объяснить, что имя должно быть в описании, но не в самом полигоне.

  • Юст Шуппе (Joost Schouppe) спрашивает какую схему тегирования туалетов для собак ему стоит вынести на голосование.

  • В списке рассылки Tagging появилось обсуждение того, как в OSM обозначать данные о проездных картах (а-ля "Тройка"), которые постепенно вытесняют проездные билеты. Овермикромаппингом такого рода предложил заниматься пользователь Warin.

  • Там же, в Tagging, Мартайн ван Экзель (Martijn van Exel) спросил про теги destination:street, которые были замечены там, где команда Telenav картировала (в основном) отходящие от motorway_link съезды в Канаде. Это недокументированный подтип тега destination. Ван Экзель спрашивает о том, как он используется, и есть ли какое-то согласованное мнение, задокументированное где-то ещё, кроме wiki OSM.

  • Юст Шуппе (Joost Schouppe) поднимает дискуссию о shop=fuel, которые уже тут упоминались. Вопрос касается магазинов, которые продают топливо, но не являются АЗС. Юст предлагает идентифицировать такие продукты.

  • Mapbox обновил спутниковые снимки над Вашингтоном, округ Колумбия. Картинки от 2015 года с разрешением в 7,5 см на пиксель отлично подходят как для маппинга (make mapping great again), так и, внезапно, для подсчёта людей по головам.

Сообщество

  • Escada взял интервью у Steve All из Калифорнии (США), о его Mapper of the Month. Интервью было опубликовано на сайте бельгийского OSM сообщества.

  • По информации Паскаля Нейса (Pascal Neis), сейчас количество картографов OSM в мире растёт, но уменьшается в Германии.

  • Достаточно ли 25.000 картографов для Германии? По словам редактора weeklyOSM, этого достаточно для городских поселений, но неохваченными остаются сельские, в которых ещё много работы.

Импорты

  • Майкл Спренг (Michael Spreng) спросил разрешение в рассылке imports о импортировании адресов в Canton of Bern (GEBADR list). Импорт был одобрен и началась пакетная загрузка, которая займёт некоторое время. Формы зданий будут улучшены по возможности.

Гуманитарный OSM

  • Паскаль Нейс (Pascal Neis) прокомментировал твит Рассела Деффнера (Russell Deffner) о валидации в Missing Maps. Этот процесс кажется внёс множество изменений в OSM.

  • Logistics Cluster обновляет ограничения на доступ к карте Южного Судана каждую пятницу. Это вызывает интерес для доставки гуманитарной помощи в эту зону.

Карты

  • Пол Норман (Paul Norman) предложил небольшое расширение для CartoCSS, которое бы уменьшило размер стиля на главной странице на треть.

  • Молли Лойд (Molly Lloyd) из Mapbox связалась с организаторами из Women's March чтобы создать карту где вы бы могли найти события Woman's March в разных городах и странах.

  • Take back the tech! использует информационные технологии для борьбы с насилием над женщинами и поощряет активность против насилия по половому признаку. Используя карту на основе OSM, люди могут сообщать о нападениях на женщин по всему миру.

  • Некоторые из проблем, с которыми столкнулись люди занимающиеся созданием значков для карт не всегда поддерживаются.

  • Стефан Бош-Плепелитс (Stephan Bösch-Plepelits) в списке рассылки Dev продемонстрировал карту общественного транспорта PTMap, основанную на Overpass API, которая отрисовывает отношения пути согласно новой схеме PTv2.

  • Юст Шуппе (Joost Schouppe) показал в своём дневнике как картирование дорог (тег highway=*) изменялось в Брюсселе.

switch2OSM

Открытые данные

  • Международный Хакатон по Открытым данным будет проходить 4 марта 2017 года. Во время публикации новости карта места проведения мероприятия ещё не работала.

Лицензии

  • Из-за проблем с авторскими правами Mapbox, проект OSM2VectorTiles прекратил свою работу. Авторы создали преемника, OpenMapTiles, свободного от юридических проблем и со своей собственной схемой векторных тайлов.

Программы

Программирование

  • Для ежегодного мероприятия Лето программирования вместе с гугл (Google Summer of Code) 2017, предлагаемые проекты собираются в нашей вики.

  • На сайте Geofabrik сообщают как в последнее время они улучшили ссылочную целостность в их выгрузках данных ОСМ. С незначительным влиянием на размер файла достигнуто сокращение времени обработки. Это стало возможным за счёт перехода на последнюю версию osmium.

Релизы

    • Mapbox выпустил ios-v3.4.0 своего инструментария для разработчиков iOS, в котором есть существенные улучшения документации и состава поставки, так же разработчикам предоставляется больший контроль над стилями и данными и многое другое. Также вышел релиз macos-v0.3.0 SDK, который соответствует версии 3.4.0 из Mapbox iOS SDK.
  • Software Version Release date Comment

  • Mapillary Android * 3.21 2017 01 15 Мелкие исправления.

  • Naviki Android;* 3.53 2017 01 15 Показывает направление движения, исправления некоторых ошибок.

OSM в прессе

  • Mapanica, ОСМ сообщество в Никарагуа, предлагает новый проект это поможет улучшить данные общественного транспорта. Это нужно для того, чтобы создать систему, которая позволит людям лучше планировать свои поездки в городе Манагуа.

  • Немецкий тв канал GRIP_RTL2 использовал созданный фирмой stamen великолепно выглядящий картостиль #watercolor OpenStreetMap для Румынии в своём эпизоде (от pascal_n). Копирайты не упомянули.

Другие “гео” события

  • Вот так выглядит здание если его отстраивают OSM энтузиасты.

  • Geospatial World написал о DigitalGlobe's AComp: "Когда спутник делает снимок, свет отражённый от земли может быть искажён атмосферой земли. Вот тут то и нужна Atmospheric Compensation (AComp) от DigitalGlobe."

  • Carlos Felipe Castillo сообщил: "Началась новая закрытая бета Blueshift!" Удобный инструмент для создания динамических карт.

  • Yorokobu из Испании собрал хорошие карты от Axis Maps.

  • Спутники Galileo подвержены странным сбоям часов.

  • Эрик Гандерсен (Eric Gundersen) показал спутниковые снимки инаугурации Барак Обамы в 2009 от GeoEye, теперь DigitalGlobe.

Why I'd dig becoming a member of HOT

Posted by dMoriarty on 7 February 2017 in English (English)

Hello HOT!

Thanks to John Crowley and Nate Smith for nominating me, it's much appreciated.

My name is Dylan Moriarty and I'm a designer at Development Seed. I've been involved in OpenStreetMap through learning Cartography at UW-Madison, & have quickly found HOT as one of the best places to contribute.

When I initially used OSM, it was simply to add in buildings to the city I was living in at the time. Then during the Ferguson protests I saw someone tweet out a call to help map Ferguson which had previously been scarcely covered. That introduced me to the idea of emergency response mapping and the amazing potential of OSM to help people on the ground level. Being able to directly aid the people giving aid is an incredible capability.

Since then I've been fortunate enough to work closely with HOT, including designing and building out the new Missing Maps website, designing the OpenAerialMap landing page, hosting various mapathons using the Tasking Manager, and helping update the Hot Summit site. It's been amazing to work with such an international and well meaning group as the OSM Community on each.

I'm interested in becoming a voting member as I see it as a great way to both add more firepower to the design aspect of HOT, and add another user focused voice in the organizations direction.

Cheers, -Dylan

HOT Voting Member Nomination

Posted by mingo23 on 7 February 2017 in English (English)

Dear HOT members,

my name is Marco Minghini and I come from Como (Italy). First of all, I wish to express my gratitude to Cristiano Giovando for suggesting my name for HOT membership. I would be delighted to become part of such a great community.

I have carried out my studies in Environmental Engineering (specialization in Geomatics and GIS) at Politecnico di Milano, where I obtained a BSc in 2008, a MSc in 2010 (both with honours) and a PhD in 2014. Since then I am working as a Postdoctoral Research Fellow at the GEOlab (Geomatics and Earth Observation laboratory) of Politecnico di Milano in Milan (Italy).

I am passionate about open source software, that I use everyday in my research activity, and enthusiastic of open data. Since 2015 I am a Charter Member of the Open Source Geospatial Foundation (OSGeo) thanks to the contribution I have given in the education, promotion and development of open source geospatial software and open geodata. Despite knowing the OpenStreetMap project since my MSc studies, it was only thanks to my PhD research (focused on Volunteered Geographic Information and Citizen Science) that I really started to study the project, to understand its evolution and impact, to analyse its applications and to use its data. After almost three years since then, I have become an experienced researcher on OSM, particularly on topics such as OSM data quality, OSM contribution patterns and contributors' motivations, and exploitation of OSM data to derive concrete products like land use and land cover maps.

Soon after my first OSM edit in 2014 I discovered the impressive work of HOT and I started devoting my time as a volunteer of this network. In addition to being a proud humanitarian mapper, over the last couple of years I have been supporting HOT and Missing Maps through the organization of mapathons at Politecnico di Milano (e.g. after the earthquakes in Nepal in 2015 and Ecuador/Japan in 2016) and the provision of support/training to different communities. When organizing these mapathons I had the plasure to know and to personally interact with Tyler Radford and Cristiano Giovando (who gave an exciting live skype call during our event for OSM GeoWeek 2015) as well as Blake Girardot, who often setup customized mapping projects for us. In particular, the kinds of events I am most proud of are the so-called "minimapathons", that are mapathons for primary school children. Notably, in March 2016 my colleagues and I organized a successful humanitarian mapathon by involving 200 10-year old students in mapping buildings for a project on malaria in Swaziland (see this post on HOT's blog).

I am also an active promoter of HOT and its activities among my research and professional network. As an example, as the responsible and point of contact of GEOlab for the GeoForAll network, in 2016 I gave a webinar on how to organize a humanitarian mapathon. I have also promoted humanitarian mapping at national events, for instance the 2016 conference of the Italian OSM community (OSMit 2016). In few days (on Friday, February 10) I will give an invited speech on "OSM for emergencies" at OSMit 2017, where I will present the activities of HOT and focus on the mapping effort of the Italian community after the terrible earthquakes occurred in 2016.

Finally, some students at Politecnico di Milano have recently found PoliMappers, an official student association which became the first European node of the YouthMappers network. I was proud that they asked me to become the Faculty Mentor of this association. The activities planned include both field mapping and remote mapping on HOT's tasks and I have already given some tutorials on how to use OSM mapping tools (until now iD, JOSM and Field Papers). Finally, last year I made my first donation to HOT as I really believe in the value of its activities.

With no doubt I will continue to support HOT in 2017 and beyond. In particular, as I have just become the Secretary of ISPRS WG IV/4 “Collaborative Crowdsourced Cloud Mapping (C³M)” as well as a member of the new EU COST Action CA15212 “Citizen Science to promote creativity, scientific literacy, and innovation throughout Europe”, I plan to make more and more people in these networks aware about the potential of humanitarian mapping using OSM. Thanks to the collaboration with PoliMappers, I will of course continue to organize humanitarian mapping events and provide the required training and support. Finally, depending on the time required, I would like to start being involved in one of the HOT Working Groups – perhaps the one on Training.

My OSM username is mingo23 and my Twitter profile is @MarcoMinghini. Here you can find an updated list of all my activities (such as events organized and papers written) related to OSM.

Thank you very much for your attention and for considering my nomination. Best regards and happy mapping to everyone!

Why I would like to join HOTOSM

[EN] Why I would like to join HOTOSM

It was short time after Nepal earthquake when I understood and measured the power of mapping, what it could do to support people in need and how open mapping could be saving lives. I start gathering with a small group of mappers is Mexico City who got together every Wednesday evening, I wanted to learn and see what else could be done. In State of the Map US 2015 with my colleague Andres Ortiz we presented “When will Mexico be navigable on OpenStreetMap” working in a technology company, Telenav, helped us to get resources to start improving the map from the roots, we started an import project to improve the Administrative boundaries of the country going from 69 valid boundaries to 2,457 . After that conference in New York everything started moving faster. In September 2015 the 30th anniversary of Mexico city earthquake took place, the National Digital Strategy Office of the Government of Mexico in the one Rodolfo Wilhelmy was Open Data Director at that time invited me to help with part of the coordination having a Earthquake drill and making different Government entities to understand the value of Open Mapping. Thanks to the experience we gained as a community with the Earthquake simulation, at the time Hurricane Patricia was about to hit the Pacific Coast of Mexico, more than 500 mappers helped to map the area in less than 48 hours following the example from Nepal. All this community efforts were mentioned in the Internet day by the President of Mexico mentioning how HOTOSM volunteers supported this national emergency.

Along with members of the LatAm and Mexico community I engage in every conference and every workshop the importance of Humanitarian Mapping and how we can improve people lives and to have a response not only after disaster but also considering long term projects in the ones we can work together with Governments and Civil Society to reduce disaster damage with the support of maps. I gave a talk in HOT summit last year named “Future of Humanitarian Mapping in Mexico” mentioning all these topics.

I feel very honored that friends like Humberto Yances and Rodolfo Wilhelmy contacted me to see if I could be interested in being a HOT member, without hesitating I told them it is a recognition I will be grateful to have. One of the opportunities I would like to focus with the National Center for Disaster Prevention of Mexico is to teach its officials how to map and create an internal group of trainers as a sustainable guarantee. The National Digital Strategy office mentioned they are very interested in support this initiative starting to map the temporary shelters and then mapping a pilot potential risk area that can show results and motivate more regions.

At this moment most of HOTOSM successful histories are in Africa and Southeast Asia, I am convinced my contribution to the organization can help to create more successful histories in other parts of the world so we can mitigate together the damages caused by disasters and create effective protocols for emergency management.

[SP] Por qué me gustaría ser parte de HOTOSM

Poco tiempo después del terremoto de Nepal fue cuando comprendí y pude medir el poder del mapeo así como ver lo que se podría hacer para apoyar a las personas necesitadas y cómo la cartografía abierta y participativa podría salvar vidas. Empecé a reunirme con un pequeño grupo de mapeadores en la Ciudad de México que se reunían todos los miércoles por la noche, quería aprender y ver qué más se podría hacer. En State of the Map 2015 con mi colega Andrés Ortiz presentamos "¿Cuándo será México navegable en OpenStreetMap", al trabajar en una empresa de tecnología, Telenav, nos ayudó a obtener recursos para comenzar a mejorar el mapa desde la raiz, comenzamos un proyecto de importación para mejorar las límites administrativos del país que solamente tenía en ese momento 69 límites válidos y lo mejoramos a 2,457. Después de esa conferencia en Nueva York todo comenzó a moverse más rápido. En septiembre de 2015 tuvo lugar el trigésimo aniversario del terremoto de Ciudad de México, la oficina Nacional de Estrategia Digital del Gobierno de México en la que Rodolfo Wilhelmy fue Director de Datos Abiertos en ese momento me invitó a ser parte de la coordinación de un simulacro de terremoto y de esa forma hacer que diferentes entidades gubernamentales entiendan el valor del Open Mapping. Gracias a la experiencia adquirida como comunidad con el simulacro del terremoto, cuando el huracán Patricia estaba a punto de llegar a la costa del Pacífico de México, más de 500 voluntarios ayudaron a mapear el área en menos de 48 horas siguiendo el ejemplo de Nepal. Todos estos esfuerzos de la comunidad fueron mencionados en el día de Internet por el Presidente de México en el que comentó cómo los voluntarios de HOTOSM apoyaron esta emergencia nacional.

Junto con miembros de la comunidad de LatAm y México cada vez que tengo la oportunidad de participar en conferencias y talleres siempre comparto la importancia del mapeo humanitario y cómo podemos mejorar la vida de las personas y tener una respuesta no sólo después de la catastrofe sino también considerar proyectos a largo plazo en los que podemos trabajar juntos con los gobiernos y la sociedad civil para reducir el daño que pueden causar los desastres con el apoyo de mapas. Di una charla en la HOT Summit el año pasado llamada "El futuro del mapeo humanitario en México" mencionando todos estos temas.

Me siento muy honrada de que amigos como Humberto Yances y Rodolfo Wilhelmy me contactaron para ver si estaba interesada en ser un miembro de HOT, sin dudar les dije que sería un reconocimiento que estaría honrada de obtener.

Una de las oportunidades que me gustaría desarrollar sería con el Centro Nacional de Prevención de Desastres de México en el cual se podría enseñar a sus funcionarios cómo mapear y crear un grupo interno de formadores como una garantía sostenible. La oficina de Estrategia Nacional mencionó que están muy interesados en apoyar esta iniciativa comenzando a mapear los refugios temporales y luego mapear un área de riesgo latente como prueba piloto que pueda mostrar resultados y motivar a más regiones.

En este momento la mayoría de las historias exitosas de HOTOSM se encuentran en África y el Sureste de Asia, estoy convencida de que mi contribución a la organización puede ayudar a crear más historias exitosas en otras partes del mundo para mitigar juntos los daños causados por desastres y crear protocolos eficaces para la gestión de emergencias.

[FR] Pourquoi je souhaite faire partie de HOTOSM

Peu après le tremblement de terre au Népal, j'ai compris et mesuré le potentiel de la cartographie, ce qu'elle peut faire pour aider les gens dans le besoin et comment la cartographie ouverte peut sauver des vies. J'ai commencé à me réunir avec un petit groupe de volontaires de la Ville de Mexico qui se réunissait tous les mercredi soir, je voulais apprendre et voir ce qui pouvait être fait. Lors du State of the Map US 2015, avec mon collègue Andres Ortiz, nous avons présenté "Quand le Mexique sera-t-il navigable sur OpenStreetMap". Travaillant dans une entreprise technologique, Telenav, nous avons pu obtenir des ressources pour commencer à améliorer la carte depuis les bases, nous avons commencé un projet d'importation pour améliorer les vecteurs des frontières administratives du pays allant de 69 limites valides à 2457 . Après cette conférence à New York, tout s'est accéléré. En septembre 2015 a eu lieu le 30è anniversaire du tremblement de terre de la ville de Mexico, le Bureau National de Stratégie Digital du Gouvernement du Mexique dans lequel Rodolfo Wilhelmy était Directeur des Données ouvertes, m'a invitée à aider avec une partie de la coordination avec un sondage et faire en sorte que différentes entités gouvernementales comprennent la valeur de l'Open Mapping. Grâce à l'expérience que nous avons acquise en tant que communauté lors de la simulation du tremblement de terre, au moment où l'ouragan Patricia allait frapper la côte du Pacifique au Mexique, plus de 500 volontaires ont aidé à cartographier la zone en moins de 48 heures suivant l'exemple du Népal. Tous ces efforts communautaires ont été mentionnés lors de la journée de l'Internet par le Président du Mexique en mentionnant comment les volontaires d'HOTOSM ont appuyé cette urgence nationale. Avec les membres de la communauté latinoaméricaine et mexicaine, je partage dans toutes les conférences et à chaque atelier l'importance de la cartographie humanitaire et comment nous pouvons améliorer la vie des gens et avoir une réponse non seulement après la catastrophe, mais aussi envisager des projets à long terme dans ceux où nous pouvons travailler en collaboration avec les gouvernements et la société civile pour réduire les dégâts causés par les catastrophes avec le soutien des cartes. J'ai donné un discours au sommet HOT l'année dernière intitulé «L'avenir de la cartographie humanitaire au Mexique» en mentionnant tous ces thèmes.

Je me sens très honorée que des amis comme Humberto Yances et Rodolfo Wilhelmy m'aient contactée pour connaître mon intérêt pour être un membre de HOT, et sans hésiter, je leur ai dit que c'est une grande reconnaissance. L'une des occasions que je voudrais mettre en relief avec le Centre national de prévention des catastrophes du Mexique est d'enseigner à ses fonctionnaires comment cartographier et créer un groupe interne de formateurs comme une garantie durable. Le bureau de la Stratégie nationale a mentionné qu'ils sont très intéressés pour soutenir cette initiative en commençant à cartographier les abris temporaires du Mexique, puis cartographier une zone pilote de risque potentiel qui peut montrer des résultats et motiver davantage de régions.

En ce moment, la plupart des histoires de réussite de HOTOSM sont en Afrique et le Sud-Est de l’Asie, je suis convaincue que ma contribution à l'organisation peut être de documenteer des experiences positives dans d'autres parties du monde afin d'atténuer ensemble les dommages causés par les catastrophes et de créer des protocoles efficaces pour la gestion des urgences.

Cokely Backcountry Skiing. Change set #45377916 by InfiNorth; approx Jan 21, 2017. Incorrect location of ski resort

Posted by Robert Copithorne on 7 February 2017 in English (English)

i would appreciate seeing comparisons of the area designated as abandoned ski resort, with the area designated cokely backcountry skiing. I believe their might be two areas, not one. If there are any old maps available to help resolve this issue, I would really like to see them.

I have an old brochure from the Mount Arrowsmith Ski Resort with a rough sketch of the ski trails, but nothing to tie the map in to. My view of the area I picked as a ski area fits the map better than the new area in my view. I can see how the new area could also be a ski area, but what distinguishes the areas?

Please reply as as I am anxious to resolve this issue.

Joining HOT

Posted by pratikyadav on 6 February 2017 in English (English)

I am PratikYadav and I work with Mapbox based in Bangalore, India. I came to know about OpenStreetMap and HOT after joining Mabox two years ago and been involved with both of them ever since. I started with taking part in the HOT projects where Mapbox team joins to help HOT in mapping and validation of various tasks over the year.From past few, month I have been working with HOT imagery coordination group to make sure the the request coming for imagrey can be quickly processed by Mapbox.

I worked with Mikel last year to understand the spatial spread of all past HOT tasks. 1

I am a big fan of HOT's work specially the concept of involving remote-volenters who are willing to help and link them to the people actually using these information on ground. My sepecific intrest this year will be to facilitate imagery coodination so that the most clear and recent imagery can be provided to mapping volenteers during crisis and how can we pre-identify and improve imagery coverage at hot spots. I talked about this last year at HOT summit (slides) and very excited to work with larger HOT team around this.

Fix for ‘Java-8 Will not Upgrade since Jan 2017’ under Debian Jessie

Posted by alexkemp on 6 February 2017 in English (English)

tl;dr: use the following from a console:

$ sudo apt install -t jessie-backports openjdk-8-jre-headless ca-certificates-java

JOSM needs Java-8. Open-Java-8 is available via Jessie Backports, but the current update (8u121-b13-1~bpo8+1) needs updated CA-Certificates which were not previously available from Backports (see Debian bug#851667). Unfortunately, Synaptic will not spot the updated certificates in Backports since it keeps holding back openjdk-8-jre, etc.. Thus, the need to use the console line as at top.

Unfortunately, I'd worked my way through the very-useful AskUbuntu question on:

“E: Unable to correct problems, you have held broken packages”

...and had therefore removed all Oracle + OpenJDK Java8 (which meant that all JOSM was also gone & all my Java alternatives reverted to Java7). However, it also meant that I had a different error message on attempted reinstall of Java-8:

$ sudo apt-get install openjdk-8-jre openjdk-8-jre-headless ca-certificates-java
  ...
  The following packages have unmet dependencies:
   openjdk-8-jre-headless : Breaks: ca-certificates-java (< 20160321~) but 20140324 is to be installed
  E: Unable to correct problems, you have held broken packages.

That allowed me to find a Unix Stack Exchange Q which solved the issue. Now I need to reinstall JOSM & make Java-8 the system default (sigh)...

Open data Regione Lazio: aree protette e corsi d'acqua nella Tuscia

Posted by 50x34 on 5 February 2017 in Italian (Italiano)

Dal febbraio 2015 la Regione Lazio ha aperto un sito http://dati.lazio.it dove sono pubblicati dati con licenza Creative Commons Attribution 4.0 CC BY 4.0. I dati geografici sono disponibili tramite il servizio WMS ed è possibile effettuare il download nei formati .CSV e .SHP. Il sistema di riferimento usato è ED50 European Datum 1950 proiettato sul fuso 33N, diverso da quello di OSM; quindi, se si vuole utilizzare queste fonti geografiche in OSM si deve necessariamente proiettare i dati, tramite ad es. QGIS, sul WGS84. Tra i 258 datasets disponibili ve ne sono alcuni interessanti per l'attività outdoors in particolare mi riferisco ai limiti delle Aree protette, parchi e riserve nazionali o regionali, ed i corsi d'acqua, fiumi, torrenti, corsi d'acqua, che in dati.lazio.it sono detti “aste”.

Aree protette

Per quanto riguarda i limiti delle aree protette, non avendo altre fonti certe di confronto e validazione, ho considerato “buoni” (alias precisi) senza operare correzioni le geometrie, anche se spesso ho notato che, almeno nei luoghi che conosco, non coincidono con quelli che dovrebbero essere i limiti fisici naturali (strade, corsi d'acqua, ponti, ecc.). Anche se probabilmente i limiti non saranno precisi, ma d'altronde anche un device GPS ha un proprio errore, reputo comunque importante avere disponibili sulla mappa i limiti perché ci informano della particolare legislazione di cui godono questi luoghi e dei comportamenti necessari da adottare. Ad oggi ho caricato i limiti delle seguenti aree protette: Parco SubUrbano Regionale MARTURANUM, Riserva Naturale Regionale LAGO DI VICO, Parco Naturale Regionale BRACCIANO – MARTIGNANO, Riserva Naturale Provinciale TUSCANIA, Riserva Naturale Provinciale MONTE CASOLI DI BOMARZO, Riserva Naturale Regionale SELVA DEL LAMONE, Riserva Naturale Regionale MONTE RUFENO, Parco SubUrbano Regionale VALLE DEL TREJA, Riserva Naturale Provinciale MONTE SORATTE, Riserva Naturale Statale SALINE DI TARQUINIA.

Corsi d'acqua

Discorso diverso per quest'ultimo tipo di dati geografici dove è possibile operare una serie di controlli per capire la bontà delle informazioni rese disponibili dalla Regione Lazio. Utilizzando le cartografie disponibili tramite WMS, CTR 1:5000, IGM 1:25000, le ortofoto PCN2012, oltre ovviamente a rilievi effettuati con il GPS se disponibili, risultano evidenti alcuni problemi che rendono inutilizzatili le “aste”: infatti, l'accuratezza della georeferenzazzione e della geometria è poco precisa (rispetto alle ortofoto del PCN2012 spesso sono tracciati in aree sbagliate e i rami dei vari corsi/specchi d'acqua non sono uniti ma spesso si intersecano), la ridondanza è presente (ci sono spesso doppioni dello stesso oggetto), la coerenza non è rispettata (vi sono molti rami, anche all'interno dello stesso corso d'acqua, che hanno verso di scorrimento invertito), infine risultano incompleti dei nomi. Insomma, queste “aste” prima di essere caricate ed utilizzate in OSM ci si deve lavorare molte ore. Nel procedere in questo lavoro di correzione, integrazione e mappatura in OSM, ho suddiviso la Tuscia in base ai principali bacini idrici: laghi di Bolsena e di Vico, fiumi Paglia, Fiora, Mignone, Arrone. Ad oggi è completo il bacino idrico del lago di Bolsena e del lago di Vico, mentre sono in via di completamento i bacini idrici relativi ai fiumi Paglia e Mignone.

Attribuzione

Concludo evidenziando come entrambi i tipi di dati geografici una volta corretti e validati sono caricati su OSM citando la fonte tramite il tag source= http://dati.lazio.it.

Туризм и tourism - в чём разница?

Posted by BushmanK on 4 February 2017 in Russian (Русский)

Всем, наверное, известен ключ tourism=. Но не все, очевидно, понимают его смысл точно. Как это часто бывает, дело в смысловой разнице между английским словом tourism и его аналогом в русском языке.

Россияне и жители некоторых стран бывшего СССР привыкли называть этим словом не рекреационный туризм, то есть путешествия налегке, без специального снаряжения, как англичане и американцы, а спортивный туризм: пешие походы, походы на плотах и байдарках, горные походы и даже альпинистские экспедиции. Это местная языковая особенность русского языка и российской (не исключительно, конечно) культуры. Если вы скажете англоговорящему человеку, что вы любите туризм, он никогда не вообразит вас идущим с рюкзаком по тундре или плывущим на плоту по бурной реке. Он представит вас, например, фотографирующим достопримечательности какого-нибудь города или относительно легко доступные природные достопримечательности. Чтобы рассказать о своем увлечении пешими походами, вам придется упомянуть hiking, а о походах и сплаве на плоту - rafting и white water rafting.

Ровно по этой причине, дословный перевод статей Wiki о тегах вроде tourism=attraction лишен смысла. Для англоговорящего, англоязычная статья читается в контексте того, что он знает о смысле слова tourism в родном языке. А для россиянина требуется давать языковедческое или культурологическое объяснение, касающееся точного смысла слов tourism и attraction, чтобы не возникали ситуации, когда кто-то решит, что речь только о парках аттракционов (на самом деле - о достопримечательностях вообще) или о точках интереса для занимающихся спортивным туризмом вроде порогов и перекатов на речках. Это не всегда очевидно (особенно, если просто изучал язык в школе или институте, но не имеешь опыта его реального применения, где вылезают ошибки из примера выше), но это так.

When you 'discover' a city that is not on OSM

If you map in the West you may come to think that the major stuff in OSM is done, but in developing countries, you may discover major unmapped features.

OSMの網羅率

日本全国でどのぐらいマッパーが活躍しているのかを示す図を作ってみました。 「国土数値情報(バス停データ)」の近くにOSMデータの「bus_stop」が近くにどれだけ存在するかによって色分けしています。

以下の図は国土交通省国土政策局「国土数値情報(バス停データ)」をもとにhayashiが編集・加工したものです。

  • 赤: データが入力されていない地域
  • 橙: データ入力が不完全。修正が必要な地域
  • 緑: データが入力されている地域

Compared with Kokudo Suchi Joho (data from Japanese Government)

  • Red: Empty Area
  • Orange: Uncompleted Area. Need more works
  • Green: Completed Area. OSM coverage bus_stop

全国の状況を見ると「OSMぜんぜんダメじゃん」って感じになっていますが、そもそも「バス停」ってアームチェアマッピングが非常にやりにくいので、このデータにはアームチェアマッパーの貢献度が全く反映されていません。 街中を徘徊するタイプのマッパーによる成果とみることができます。

神奈川県周辺

全国では状況が分かりずらいので神奈川県周辺にズームしたのが下図です。 OSM coverage bus_stop 神奈川県 神奈川県は半分ぐらいできてますね。

実は神奈川県東部周辺には「バス停」マニアが何人かいるようです。西側は手つかずのところが目立ちますが、過去にマッピングパーティが行われたところ(熱海など)は局地的に入力されています。

大阪

OSM coverage bus_stop 神奈川県 大阪は淀川の南側はたくさんのマッパーが散発的にマッピングしている感じですが、北部と奈良盆地北部に関してはきっちりと入力されています。少数(おそらく一人)のマッパーが計画的にバス停をつぶしていってように感じます。

札幌周辺

OSM coverage bus_stop 神奈川県 札幌も明暗くっきりって感じでマッピングされています。この画像には入っていませんが室蘭市はほぼコンプリート状態になっています。

このデータは公開しています!

ここで示したデータはこの記事を読んでいるOSMマッパーのために公開しています。 私の自宅に転がっているRaspberry Pi2をサーバーとしてDynamicDNSで運用しているのであまり接続率は良くないかもしれませんけど・・・

PostGISのデータとして公開します。QGISを使って「PostGISレイヤの追加」すれば誰でも自由に見ることができます。まだ入力されていないバス停を探索したり、他のマッパーが活躍している地域を探すのに便利だと思います。是非、活用してください。

OsmCoverageデータの利用方法

バス停以外の指標

今回は「国土数値情報(バス停データ)」を指標として使ってみました。OSMにはインポートできない「国土数値情報」もこんな感じなら利用することができます。

「バス停」以外にも利用可能なデータはないでしょうか?

国土数値情報では「燃料給油所」なんかも同じように使えそうです。コンビニのデータなんかもあれば指標としてみると面白いかも。

ライセンス的にOSMに投入するのが難しくて諦めてしまったデータも、もう一度見なおしてみるとけっこう使えるものが発見されるかもしれませんね。

Engaging High School Geography professors with OpenStreetMap

Posted by Mapanauta on 4 February 2017 in English (English)

Note: English [EN] please find the Spanish version below [SP]

[EN] Last week some members of the OSM Mexico Community had the chance to participate in the first OSM Training focused in Geography professors from High Schools located in municipalities close to the State Capital, Toluca. It was a four day event in the University of the State of Mexico. First Day It was the opening day and Edgar Lemus gave the Talk “Democratization of GIS OSM for high school education” making the professors aware about the importance of open source GeoTechnologies to get more involvement from the students and benefits in the societies. The second part of the event Edgar Lemus and myself gave the following topics to do a full immersion of the professors in the OSM world:

  1. What is Open Data? What is OpenStreetMap? What are the benefits of using OpenStreetMap?
  2. Humanitarian OpenStreetMap
  3. Mapping with ID Editor
  4. Mapping with HOTOSM Tasking Manager

Edgar Lemus presentando

Second Day The participants were previously warned the second day will be though but at the end of the day they will be knowing different tools they could use to adapt to current or future projects. So, it was a 100% mapping in the field day. Along with the professors it was decided to use every tool one hour so we could take advantage of the day out and then go back to the faculty to have pizzas for lunch (the mapper fuel!). We gathered at 9 am in Café con Leche restaurant (yes! It was added to the map) so at 9:20 we started it. a. Field papers We gathered in Los Portales an area very well located in Downtown Toluca. The previous day with the organizer Sandra Hernandez we defined an area easy for walking and divided it in four quadrants so we created teams, they will be responsible to cover the larger area as possible in one hour. The professors were very surprised to see the map and then compare it with reality. In average, each team added between 25-30 POIs in just a few blocks in downtown Using Field papers Picture-Using Field papers

b. OSM Tracker After using Field papers one of the professors asked “how can we be sure adding data manually with field papers will be exactly where it should be? So the answer was OSM tracker the next tool will give you a more exact location. We moved to a pedestrian street to capture the POIs and tracks and show them how to upload them to OSM. The professors were fascinated with the tools and we were just half the way. Banks, Convenience Stores, Restaurants, Pubs, Money Exchange among other were added to the map of Toluca. Tracks of OSMTracker Picture-Traces with OSM Tracker

c. Mapillary The first objective was to do a Mapeatón exercise in Downtown but the sidewalks and everything was so clean, organized and inclusive that the exercise migrated to do a walking exercise using two teams. Each team will be having three different phones so one could look forward, the second could look sideways and the third one could be looking backwards. The photomapping took place in a beautiful area with churches from the 18th century and gardens surrounded of history. Check the link so you can have a look.

d. OpenStreetCam After three hours of walking, we still had a tool to use, OpenStreetCam, but this time our feet were able to relax ;) because we used taxis to do the photomapping. Again field papers were used to print a larger area of Toluca downtown and divided in four, so four teams will be doing a photomapping of the assigned area. In one hour the teams had to go back to the Geography faculty and try to get the most tracks as possible in that amount of time. Toluca before Picture-Toluca Before

Toluca after Picture-Toluca After

e. Back in the faculty after the pizza break all the tools were showed in the screen so the Geography professors could have a broad overview of all the capabilities and how their own projects or student’s project could be having the benefit of OpenStreetMap

Third day El desbaste map a collaborator that mapped the city of Lerma and is working in the same Municipality as Chief of Design and Social Policy showed the professors how a city can be managed through all the Open Data generated by OpenStreetMap. How the city of Lerma has planned the trash collection using OSM data and even how citizens with economic difficulties can apply to social benefits. El Desbaste map showing the achievements in Lerma Also, the same day Beny Carbajal presented JOSM, Beny is a GeoInformatic graduated student who has been very active in OSM since the first Open mapping day last year and has been collaborating in HOTOSM activations, she is preparing herself to be part of the team who is sharing the OSM tools around Mexico. Beny presenting JOSM Fourth day After three intensive days, the professors defined a project in the one they will be using OpenStreetmap and the tools learnt to involve students and share the knowledge they just learned. Stay tuned for a blog from Sandra Hernandez in the one she will be explaining the projects and the results they are expecting in the High Schools of the State of Mexico

Formación de profesores de geografía en OSM

La semana pasada, algunos miembros de la comunidad OSM México tuvimos la suerte de participar en la primera Formación en OSM enfocado en profesores de geografía de Preparatorias ubicadas en municipios cercanos a la capital del estado, Toluca. Fue un evento que duró cuatro días y tuvo lugar en la Facultad de Geografía de la Universidad Autónoma del Estado de México.

Primer día.

El primer día Edgar Lemus (ealpv) dio la charla " Democratización de Tecnologías de Información Geográfica", el objetivo de esta charla es hacer los profesores conscientes de la importancia de geo-tecnologías de código abierto para conseguir una mayor participación de los estudiantes y dar beneficios sobre los datos obtenidos a las sociedades. La segunda parte del evento Edgar Lemus y yo participamos dando los siguientes temas para hacer una inmersión total de los profesores en el mundo OSM:

  • ¿Qué es Open Data? ¿Qué es OpenStreetMap? ¿Cuáles son los beneficios del uso de OpenStreetMap?
  • Humanitarian OpenStreetMap
  • Mapeando con ID Editor
  • Administrador de Tareas con HOTOSM

Segundo Día El segundo día estuvo dedicado a herramientas de campo. Los participantes estaban prevenidos que estaría pesado, sin embargo al final del día tendrían el conocimiento suficiente para utilizar diferentes herramientas adaptadas a proyectos futuros. Junto con los profesores se decidió dedicar una hora a la utilización de cada una de las herramientas y así aprovechar el día, posteriormente volver a la facultad a comer pizzas (¡el alimento preferido en mapatones! considerado el combustible para los mappers). Nos reunimos a las 9 am en Café con leche (sí! Fue añadida al mapa) y arrancamos el ejercicio a ls 9:20.

a. Field papers- Papeles en campo

Nos reunimos en el área de Los Portales, un área muy bien situada en el centro de Toluca. El día anterior junto con la organizadora Sandra Hernández definimos el área para poder caminar fácilmente, fue dividida en cuatro para crear equipos, ellos serían responsables de cubrir el área lo más que se pueda en una hora. Los profesores se sorprendieron mucho al ver el mapa y luego compararlo con la realidad. En promedio cada equipo añadió Entre 25-30 puntos de interés en sólo unas pocas cuadras en el centro de Toluca.

b. OSM tracker (Link Imagen del centro o Toluca) Después de utilizar Field papers, uno de los profesores preguntó "¿cómo podemos estar seguros que agregando datos de forma manual será ubicados exactamente donde deberían ser? la respuesta fue que la siguiente herramienta OSM Tracker le dará una localización lo más exacta posible. Nos mudamos a una calle peatonal para capturar los puntos de interés y las trazas, también se mostró cómo subirlos a OSM. Los profesores estaban fascinados con las herramientas y estábamos sólo la mitad del camino. Lugares como bancos, tiendas de conveniencia, restaurantes, pubs, casas de cambio, entre otros fueron añadidos al mapa de Toluca.

c. Mapillary Originalmente el objetivo era hacer primero es un Mapeatón (enlace a blog Ce) usando Mapillary pero afortunadamente las aceras del centro de la ciudad estaban limpias, organizadas e inclusivas. Por lo tanto el ejercicio fue modificado y se crearon dos equipos para hacer una caminata en el centro. Cada equipo tuvo tres teléfonos en diferentes posiciones, el primer miraría hacia el frente, el segundo miraría hacia un costado y el tercero estaría mirando hacia atrás. El fotomapping se dio a cabo en un lugar con iglesias del siglo 18 y jardines rodeados de historia. Checa el enlace para que puedas ver lo que hicimos.

d. OpenStreetCam Después de tres horas de caminata, todavía quedaba una herramienta por utilizar, OpenStreetCam, en esta ocasión nuestros pies tendrían tiempo para relajarse ;) ya que utilizaríamos taxis para hacer el fotomapping. Nuevamente se usaron field papers para determinar el área que se quería cubrir y en esta ocasión era de mayor cobertura y también fue dividida en cuatro, por lo que cuatro equipos estarían haciendo el fotomapping del área asignada. En una hora los equipos tratarían de conseguir el mayor número de trazas posibles para después reunirse nuevamente en la facultad de Geografía.

e. De vuelta en la facultad después del lunch se mostraron en la pantalla todas las herramientas para que los profesores de geografía tuvieran una visión general de todas las capacidades y cómo aplicarlas a los proyectos de sus estudiantes o a sus propios proyectos y así tener el beneficio de OpenStreetMap.

Tercer día

El Desbaste Map colaborador de OSM que llevó a cabo el mapeo de la ciudad de Lerma actualmente trabaja en el Gobierno de la misma ciudad como Jefe de Diseño de Política Social. El mostró a los profesores como se pueden aplicar políticas de gestión a través de los datos abiertos generados por OpenStreetMap, un ejemplo es cómo la ciudad de Lerma planea la recolección de basura a partir de datos de OSM y ciudadanos con dificultades económicas pueden solicitar apoyos sociales a partir de los datos.

Beny Carbajal presentó la herramienta JOSM, Beny es una estudiante recién egresada de Geoinformática, ella junto con varios estudiantes de la UAEMX han sido colaboradores muy activos en OSM desde que participamos en la 1ra Jornada de Mapeo Libre y también han estado presentes en activaciones HOTOSM, ella se está preparando para ser parte del equipo de talleristas OSM que está dando difusión a las herramientas de OSM por todo México.

Cuarto día

Después de tres días de intensa actividad, los profesores definieron un proyecto en la que van a utilizar OpenStreetmap y las herramientas aprendidas, estarán invitando a estudiantes a participar y compartir con ellos los conocimientos que acaban de aprender.

Estén pendientes del blog de Sandra Hernández en el estará explicando los proyectos de los profesores de Geografía y los resultados que esperan obtener en las Preparatorias del Estado de México.

Hi, I'm Elida!

Hi, all. I'm Elida!

Thank you Joseph Reeves, for nominating me to be one of new HOT voting member. I am an Indonesian, and have been a member of HOT Indonesia since 2012 in a project entitled "Scenario Development Planning for Contingency Plan (SD4CP)" where OSM data were applied to generate realistic disaster impact to critical infrastructure. Up until now, I have involved in several activities related to HOT projects (SD4CP, POI Mapping, Bengawan Solo Mapping, Trenggalek Mapping, University Roadshow) -all of them are located in Indonesia- ranging from develop curriculum and training module, deliver training, arrange mapathon, and bring an end to end OSM data collection and usage for specific purpose -mainly in disaster field.

Activities during Bengawan Solo and Trenggalek Mapping

Since HOT is first place where I learned OSM, HOT means a lot to me. It allowed me to meet a new collaborative mapping tool, with huge potential use and the spirit of community empowerment. It also gives me opportunities to learn it from the masters, such as Kate Chapman and Joseph Reeves (thanks for introducing me to OSM) and also Russell Deffner and Mhairi O'Hara (thanks for teaching me HOT activation).

As a voting member, I want to be more actively involved in HOT decision making and share my ideas to meet the problems or challenges in the future.

I haven't been involved in HOT project outside Indonesia. But, in Indonesia, the biggest challenge related to either HOT or OSM, is the sustainability of the mapper (local mapper) to continuously map in OSM. I don't know whether this happens in other countries or not. To meet that challenge, I think we have to keep in touch with the mappers either online or offline, and encourage each other to keep mapping.

If you want to know more about me, I would happy to have a talk with you ! For further discussion, feel free to contact me using this email : uswatunkh21@gmail.com
