I'm looking at the diary entries once a day now. All too often there is spam content. What can we do about this? Maybe a vote button and if 3 people mark an entry as spam, it is removed from view and verified by an admin?


State of the Map Validation notes

Posted by manoharuss on 25 September 2017 in English (English)


State of the Map 2017 attendees

State of the Map 2017 was a lively event. This was my first attendance at a State of the map conference. There was good participation from experienced community members from different parts of the world along with members from OSMF, DWG and from companies such as Mapillary, Telenav, Facebook, Apple, GeoRepublic, Grab and more.

It is wonderful to be part of this vibrant community. I have Mapbox to thank, for introducing me to OpenStreetMap and allowing me to work with passionate people for mapping, documentation and validation. I would like to use this diary post to answer some of the recurring questions on OSMCha and some notes from State of the Map 2017.

  • Arun's talk made it clear that new mapper validation catches 60% of all cases of data issues on OSM. This was already a reason in OSMCha for participants to try out during the validation workshop.

  • I felt that there was a common agreement on peer reviewing amongst local mappers from the SoTM attendees. This promotes constructive feedback, builds a stronger community and results in better data quality.

  • It was great to meet Frederick Ramm from DWG. The workflow the validation team at Mapbox follows has been similar to how DWG approaches in fixing issues, escalations and in sharing feedback to users to become core mappers.



  • OSM-Compare is the open library of GeoJSON comparison rules that flags problematic edits in OSMCha
  • We can use OSM-Compare not only for identifying odd changes on OSM, but also as a social tool or watchlist of certain feature edits:
    • I saw passionate rail mappers at SoTM, I think it would help to flag changesets with rail edits so OSM users can identify and interact with each other, in local communities.
    • Blake Girardot recently opened an issue to flag any changes to man_made=survey_point features. This is now a compare function in OSM-Compare ready to flag the first such change in OSMCha.
    • If you have any other niche use case of OSM-Compare that you would like to use it for, awesome!! Please feel free make an issue and I can help you write a compare function in OSM-Compare that you can use as a reason in OSMCha.

Join us in validation

If you are new to OSMCha and not sure where to start, going through review_requested changesets in your local area is great way to begin. This is a new feature that landed in iD editor on OpenStreetMap. These are the steps I would follow:

  • Set the OSMCha filter for changesets with the reason Review requested . This link will set it for you.
  • Open the filters and modify the bbox to your local map area that you want to review.
  • Hit Apply to view the list of changesets that was requested for review
  • Go through the changesets and submit feedback to the mapper by commenting on the changeset on OpenStreetMap based on your assessment.

Llanollen Canal

Posted by NorthIsland on 25 September 2017 in English (English)

Went along the Llangollen Canal this year and surprised that there was very little landuse on OSM. Based on memory and aerial photo, I am woring my way from Llangollen to Ellesmere. Perhaps this will inspire more to visit! On the Farmland/Meadow issue, I tend to map according to ground colour. I follow those who think that Farmland is crops and Meadow is for grazing. meadow could be ploughed. If you can see worn tracks, lots of individual trees, growth variation, or steep slopes, then it's probably meadow. Still waiting for someone to come up with a rendering for Fell....

My FOSS4G - Boston Experience

Posted by feyeandal on 25 September 2017 in English (English)

Last August 16-19, 2017, I attended the International Conference For FOSS4G held in Boston, Massachussets, USA. It is an annual recurring global event hosted by OSGeo. The FOSS4G (Free and Open-Source Software for Geospatial) conference is the largest global gathering focused on open source geospatial software. It brings together developers, users, decision-makers, and observers from a broad spectrum of organizations and fields of operation. FOSS4G I was one of the ten travel grant awardees under the OSGeo Travel Grant Programme (TGP). Through the financial support from OSGeo and UP NOAH have provided me, I was able to attend FOSS4G. It has given me the opportunity to gain knowledge on the on-going open-source projects around the world. My participation from the conference has provided me direct access to presentations from many organizations within the open-source community, allowing me to gain valuable information about what other projects are all about and where they are focusing their efforts. Attending this conference has provided me with opportunity to learn more about the latest free and open-source software for geospatial technologies and developments, but also increase visibility for the research organization I am working for, UP NOAH. FOSS4G

Favorite Sessions

  1. Breaking Up is Easy to Do: Leaving ESRI Behind for QGIS – A Case Study FOSS4G This, perhaps, was one of my favorite sessions. Alex Cohn discussed the reasons why their organization made a transition from using ArcGIS to QGIS and explained the impacts of this transition on their everyday operations for two years.

  2. It’s About People: Putting the ‘Community’ in ‘Open Data Community’ FOSS4G This session was basically focused on solutions and challenges to empowering collaboration within the community using the MapStory project. MapStory is a free and open-source platform for crowd-sourcing global spaciotemporal data. Since it is a participation-focused open data platform, it emphasizes and revolves around the contribution of the global community.

  3. Lastly, I enjoyed listening to the talk of Steven Feldman about Fake Maps. Obviously, it was telling us about the power of maps that may mislead people through the message of the map intentionally, or through a lack of understanding. It was a fun and chill talk by Steven and I am sure that everyone loved it.

The Keynote

There were 5 keynotes for this year's conference and I must say that one really stood out -- the keynote from THE Richard Stallman. Dr. Richard Stallman launched the free software movement in 1983 and started the development of the GNU operating system in 1984. It is a free software -- everyone has the freedom to copy it and redistribute it, with or without changes. It was a pretty long keynote though, but surely leaves discussion within the community about what an open-source software really is.

Wrap Up

Attending FOSS4G was quite rewarding for me. It is an opportunity that should not be missed. It was also great to meet the geo-geeks and learn so much from them.

I would want to take this chance to thank everyone involved in making this conference possible.

Next year, it will be held in Tanzania in August, and I hope to be there!

May the FOSS be with you!

The case for highway=trunk on Texas frontage roads

Posted by claysmalley on 24 September 2017 in English (English)

You can tell where someone's from in Texas by what they call that smaller road parallel to the highway. A Dallasite may call it a service road, a San Antonian might say access road, and every other Texan will tell you it's a frontage road, except of course Houstonians who swear by feeder. Regardless of what you call it, it's a ubiquitous thing across the urban areas of Texas. Everyone's driven on 'em.

So why are they so chaotically mapped? an example of a highway in El Paso As it is right now, they're typically mapped as highway=secondary throughout, switching to highway=primary or even highway=trunk when they're part of a freeway exit for such a road. This happens regardless of the lack of any underlying changes to the frontage road itself. If I showed you a cropped image of a frontage road segment tagged highway=secondary and another nearby segment tagged highway=trunk, you probably wouldn't be able to tell the difference.

This ends up looking kinda janky and ugly. But more importantly, it doesn't do a good job of describing the roadway it's supposed to represent. If you take out the freeway and leave just the frontage roads, it's a wide boulevard with massive spacing in between median crossovers. That alone merits highway=trunk.

And, lo and behold: we already do that where the freeway hasn't yet been built but its surrounding frontage roads have been. an example of a highway in Houston In good faith, I'm going to be changing most urban Texas frontage roads to highway=trunk. I hope this makes sense to people, and if you have any concerns, feel free to shoot me a message.

Viverone Mapping Party

Posted by Andrea Musuruane on 23 September 2017 in Italian (Italiano)

Poster Domenica 1° ottobre 2017 OpenStreetMap organizza un mapping party a Viverone (BI).

L’evento si svolge in collaborazione con il BiLUG Biella Linux User Group, l'IvLUG Ivrea Linux User Group, lo ZAC! Hackers' Café di Ivrea, la Compagnia dell’Armanac di Santhià e con il patrocinio e supporto del Comune di Viverone e dell'Associazione Slowland Piemonte.

OpenStreetMap (OSM) è un progetto aperto per creare e rendere disponibili dati cartografici, liberi e gratuiti, con una logica collaborativa simile a quella di Wikipedia.

Un mapping party è un evento durante il quale nuovi appassionati ed esperti si ritrovano per rilevare un luogo e passare una giornata insieme. Tutti sono benvenuti e in particolare chi vuole saperne di più su OpenStreetMap e gli open data.

Il ritrovo è fissato per le 9.45 presso la Biblioteca, Via Umberto I 109, 13886 Viverone (BI).

Il programma sarà il seguente:

  • ore 9.45 ritrovo presso la biblioteca
  • ore 10.00 inizio lavori e spiegazione introduttiva
  • ore 10.30 divisione in gruppi e passeggiata con raccolta dati attraverso le vie di Viverone
  • ore 13.00 pranzo al sacco
  • ore 14.00 elaborazione dei dati raccolti e inserimento dei dati in OpenStreetMap
  • ore 18.00 conclusione della giornata

L’organizzazione fornirà le nozioni necessarie per poter raccogliere i dati sul territorio e le mappe cartacee su cui appuntarli. Alcuni collaboratori di OpenStreetMap seguiranno e aiuteranno i neofiti durante la rilevazione.

Chi vuole può portare:

  • un ricevitore GPS, per acquisire tracce GPX e annotare waypoint
  • un macchina fotografica digitale, per georeferenziare le foto
  • uno smartphone, da usare come ricevitore GPS o come macchina fotografica digitale, oppure per l'uso di applicazioni specifiche (OsmAnd, OSM tracker, OSM Contributor, Street Complete, Vespucci)
  • un computer portatile, per l'inserimento dei dati tramite JOSM

Durante la giornata sarà presente anche Alessandro Palmas, Project Manager OpenStreetMap per Wikimedia Italia.

Per motivi organizzativi, si pregano gli interessati di segnalare la loro partecipazione.

San Diego County Bus Stops and Bus Routes

Posted by mds08011 on 21 September 2017 in English (English)

I am in the process of trying to update and add bus stops and bus routes in San Diego County. The majority of current bus-stops are based on old data and are many are just a single located at an intersection. MTS and SANDAG have new SHP layers and update this information quarterly. I am approaching this in pieces so as to not break any functionality of the existing bus routes in OSM. However, from what I have seen, the vast majority of bus stops need to be changed and many routes are not added yet.

Streets as Areas

Posted by BjornRasmussen on 21 September 2017 in English (English)

I recently added "area roads" to downtown Durham, NC. I made the surface of the roads visible on Openstreetmap. I was wondering if their is any specific way to map road areas. I currently map them as "area = highway" and "highway = service". Feel free to check it out!

Downtown Durham

Downtown Chapel Hill

All three links lead to a place in Openstreetmap where I mapped roads as areas.

I anyone else mapped roads as areas, please reply a link to the location!

A hospital on every street corner in South Korea?

I'm tempted to replace all those named as clinic by the tag amenity=clinic, but maybe someone who has lived in Korea can confirm if that's appropriate?

A cow made of corn

Posted by Minh Nguyen on 20 September 2017 in English (English)

It’s corn maze season in North America: for a couple months, farms all over are inviting folks to explore mazes they’ve cut out of corn fields.

CVNP A corn maze in Northeast Ohio by David Fulmer, CC BY 2.0.

In OpenStreetMap, several corn mazes have been micromapped across Southwest Ohio. The designs change each fall, so the mazes have to be micromapped all over again.

Wendel Farms pumpkins Look sideways: these pumpkins at Wendel Farms were previously visible in Bing and other aerial imagery, but the ways clearly need to be deleted now that the pumpkin design has been cut down (and replaced).

None of the aerial imagery providers have this fall’s maze designs yet – after all, these doodles are only weeks old in some cases. So I turned to the farms’ websites and Facebook pages, where farmers have posted aerial photos of their own mazes. I wrote to them, briefly describing OpenStreetMap and asking permission to update the map based on their photos. A few got back to me, happily giving permission. It’s free publicity for them, after all.

Wendel Farms cow This year, Wendel Farms’s corn maze depicts a cow surrounded by various dairy products.

Since my preferred editor, iD, currently lacks support for overlaying arbitrary images, I built a copy locally and modified it to display the photo above the normal imagery and below the data. Using my browser’s Web inspector, I added a pattern to the SVG document’s <defs> element:

<pattern patternUnits="userSpaceOnUse" id="maze" width="956" height="1174">
    <image x="0" width="956" height="1174" href="dist/img/pattern/maze.jpg" y="200" />

and overrode the CSS style of the <path> element representing the edges of the field:

.area-fill > .w107158117 {
    fill: url("#maze") !important;

I probably could’ve done something more sophisticated to keep the image anchored while panning and zooming, but this was good enough for a quick, informal micromapping project.

Wendel Farms cow

Not too long from now, these corn mazes will’ve been cut down and plowed under, and the paths will also be deleted from OpenStreetMap in anticipation of next year’s corn maze season. But a snapshot of this fall’s designs will eventually appear in the standard aerial imagery and remain there for years to come. As a result, mappers can compare a corn maze’s appearance and the date on which the maze was micromapped to determine the vintage of the surrounding area’s imagery.

In the meantime, if you poke around Southwest Ohio, be on the lookout for cows and other scenes hidden among the cornstalks.

Survey on organised editing

Posted by OSMF Data Working Group on 20 September 2017 in English (English)

The Data Working Group is conducting a survey as part of its work on a policy covering paid mapping.

When OpenStreetMap started, it was largely a project of hobbyists contributing to OSM in their spare time. They chose freely what to map and which tools to use, and they took individual responsibility for their contributions.

The continuing growth and popularity of OSM have also brought more and more organised mapping efforts, mostly in the form of companies setting up paid data teams to improve OSM data in specific regions or for specific use cases, but also unpaid groups like school classes that are directed to work on OSM.

These organised mapping efforts are an integral part of today's OSM contribution landscape and, when done well, help make OSM better and more widely known.

In order to ensure good communication, and a level playing field, between individual community members and organised editing groups, the OSMF Data Working Group has been tasked with developing guidelines for organised groups. These guidelines will above all set out some transparency requirements for organised groups - things that are already voluntarily followed by most groups today, like informing the mapping community about which accounts edit for the team.

We have prepared the following survey with a few questions about such a policy to give us a better understanding of what the mapping community expects from such a policy. The survey is aimed at everyone editing (or planning to edit) in OSM, whether as individual mappers or as part of a team, and your answers will help us in fleshing out a draft policy.

Within the scope of the survey, and the policy to be written, we define paid mapping (or paid editing) as any editing in OSM performed by someone who is told by a third party what to map (and potentially also how to map it) and who receives money in exchange. We define other organised mapping (or editing) as any editing that is also steered by a third party, but where no money is paid.

Gravar tracks / trilhas usando gps automotivos

Posted by Tomio on 19 September 2017 in Brazilian Portuguese (Português do Brasil)

As vias dos novos loteamentos normalmente não estão visíveis nas imagens satelitais disponíveis no OSM para edição, em razão da frequência de atualização das mesmas. A solução é percorrer as novas vias, gravando tracks/trilhas gpx para utilizar nas edições.

Realizei alguns testes comparativos, gravando alguns tracks utilizando um gps automotivo Garmin Nuvi 2580 e um gps de mão, o Garmin 76csx.

Para obter uma maior precisão, em ambos gps foram desativadas a função "Lock on road". Isto é muito importante, para forçar o gps a gravar a sua real localização. Sem este procedimento, o equipamento realiza "correções" a fim de coincidir a localização com o mapa visualizado na tela, obtendo um track impreciso.

No Garmin 76csx, o procedimento consiste em:

Nos gps automotivos Garmin Nuvi, o procedimento varia um pouco conforme o equipamento, mas de forma geral:
- nuvi 1000 ou superior:
- nuvi 2xx e 7xx:
- nuvi:

Após a gravação, foi realizado o efeito comparativo e concluíu-se que a diferença entre os tracks gravados pelos equipamentos é praticamente desprezível:

  • Exemplo 01:

  • Exemplo 02:

  • Exemplo 03:

Assim, os colaboradores do OSM que quiserem utilizar seus gps automotivos para obter tracks para edição, podem fazê-lo sem maiores problemas. Ou podem ser adquiridos equipamentos usados a preços reduzidos, viabilizando os mapeamentos.

Quem tiver interesse, mesclei os tracks do gps Garmin 2580 com o Garmin 76 e subi para as trilhas do OSM:
