Mapper of the Month: Sarah Hoffman (Germany)

Posted by escada on 2 December 2016 in English (English)

This is my translation of Sarah's text in German. Any misrepresentation is my fault.

Who are you?

My name is Sarah, I am from Germany and live in Dresden. I studied computer sciences and work fulltime as software developer for a small local company. In OSM I am known as lonvia, which is a word play with the Latin form of 'long journey'.

Lonvia

Where and when did you discover OpenStreetMap ?

In 2008, I read a short article about OSM on the German online-service heise.de, which made me curious. I lived in [Switserland]((http://www.openstreetmap.org/relation/51701)) back then. Very little of Zurich was mapped, and the rest of Switserland was mostly blank. I spend a complete summer traveling along and mapping a large part of the railway network in Switserland. After that I started with hiking paths. I always loved hiking and it was great to combine the old hobby with the new one. Mapping brought me in places that I would otherwise never have visited for one-day journeys. I walked the complete Jura-Höhenweg, a very beautiful trail which is more sporty than one would expect from a brief look at the map.

What do you map?

In addition to the hiking trails, I prefer to add basic infrastructure: streets, paths, POIs that are interesting for tourists, as well as an occasional address. This has changed little over the years. I add what I would like to find on the map myself.

Lately, I am getting interested in 3D-building mapping. I think that basic building information such as the number of levels is usefull to form a rough idea how a village of neighborhood looks like in reality.

How do you map?

I am a classical outdoor mapper. I used to go out with a photo camera and GPS-tracker and added the information via JOSM. Nowadays, I track with the Android-App OsmTracker. For small improvements, I like to use Android-Editor Vespucci. I use aerial imagery mainly for the final details.

Where do you map?

I am a rather impatient mapper. Systematically surveying complete neighborhoods is not my cup of tea, neither are long sessions of armchair mapping such as MapRoullette or HOT-activations. My mapping is a result of travelling and hiking journeys. Nowadays, I only find time to map during holidays.

What is the biggest challenge for a mapper?

Working together on the map. It is often more convenient to maintain your focus strictly on your own interestes and only map for those. However, without a certain regard for the interests and work of the other mappers, this will inevitably end in frustration. It starts with making decisions about tag use and continues through every edit that touches existing data. On top of that, there are a lot of unwritten rules to mapping, which we have developped through years of trail-and-error. They may be obvious to long-term mappers but are not always logical to a new mapper.

Why do you map? What motivates you?

I have always been fascinated by maps, but until the arrival of OSM, maps could only be consumed passively. What annoyed me the most, was that there were always two types of maps: on one hand detailed topological maps, with a small scale, and on the other streetmaps, that focussed on car drivers and often left out details that I found interesting. OpenStreetMap offered for the first time the possibility to build maps that I needed: a map that could be used as pedestrian and cyclist that can show the whole picture as well as the smallest detail.

What is the hardest part while mapping ?

For me, the most difficult part is to keep the map up-to-date. As long as one is looking at a blank canvas, it is easy to stay motivated to add new elements. Mainly because one sees the next day what one has done. This is less obvious when one walks through a shopping street and updates all shops. This takes a couple of hours work, while the map seemingly did not change.

What are your mapping plans in the near future?

As I already mentioned, I am not the person that plans her mapping projects. As a software developer I am interested in the project that tries to clean up the so called Old-Style-Polygone. These are multi-polygons, where the tags are not on the relation but on the ways that form the polygon. Those areas are difficult interpret by software. Quite often, one has to guess, because the ways contain conflicting information. Currently there are around 200.000 such objects in the database. I think this can be solved rather quickly, when we join forces. This is also a good moment to bring the data up-to-date, as many such areas are a couple of years old. Maybe I will become an armchair mapper for the duration of this project.

Do you have contact with other mappers ?

When I lived in Switserland, I often went to the Züricher Stammtisch and I was also there when the Schweizer OSM Vereins was founded. In the meantime this became an official Local Chapter. Nowadays, I can occasionally be found at the Dresdner Stammtisch Besides that, I have visited several State of the Map-conferences. With the Swiss Mappers

Do you use OSM yourself?

For day-to-day use I have OsmAnd on my smartphone. At my desktop, I basicly use osm.org for everything that requires a map. For access plans and the like, umap is very usefull.

Do you do anything besides mapping?

I am involved a lot in the software development around OSM. My most important projects are Nominatim, the software behind the searchbox on openstreetmap.org; and waymarkedtrails.org, which is a website that can display all possible routes that are found in OSM.

Furthermore I am a member of OWG, the Working Group, which is responsible for the servers on which OSM run.

Can you tell us a bit more about Nominatim ?

I came to Nominatim in 2012, when they were looking for a new administrator for the official server of the OSMF. From that moment, I take care of the server and have become the lead developer for its software. Unfortunately, there are not a lot of other developers. The last few years, the only development that was done was to allow it to keep up with the enormous grow of data in the OSM database.

Nominatim

And what about waymarkedtrails ?

I started with waymarkedtrails.org, because I needed a map with the hiking trails in Switserland, so I could verify the data that I added myself. Later on, I extended the map to cover the whole world, to motivate other mappers to start mapping routes. That is one of the things that works amazingly well in OSM. As soon as one visualizes data, one finds plenty of mappers that start mapping that kind of data.

In 2012, Guttorm Flatabø from Western Norway Research Institute found out about the map and used the software for a EU-project about tourism. During that project, a mobile version was developed as well as the support for the elevation profiles. We also came up with the name waymarkedtrails during that period as well as the current look and feel of the website.

The Wintersports map and horse riding map were developed together with Michael Spreng and Robert Whittaker.

It might be interesting to note that the map gets more visits from GPSies.com, a German site to visiualize GPS-tracks, than from waymarkedtrails.org.

waymarkedtrails.org

... and to end ... is there something else you want to tell?

Happy Mapping!

A Modern (Post-Modern?) Garden

Posted by alexkemp on 2 December 2016 in English (English)

Mapping within the St James ward of Gedling today, and in particular a set of flats on Beckett Court. There are gardens at the rear of the flats. So often in these circumstances, the fact that no single family has responsibility for the gardens means that they end up derelict. That is not the case here. This garden is immaculately maintained.

This is the garden for you to judge for yourself. Personally, I've never seen another garden like it. The section on the left that you cannot see is plain grass (and, in spite of the colour, I swear that this is natural grass rather than some kind of synthetic variant). I'm not qualified to make any judgement on it, so will not even try:

Just up the road from that garden are yet more of those plaster creatures that I love to find:

Results and new initiatives after #GeoChicas #Geoladies event in Sao Paulo, Brazil

Posted by Mapanauta on 1 December 2016 in English (English)

English Version (Spanish version below)

Last week on November 24th, one day before starting the 2nd State of the Map LatAm (#SOTMlatam2016) taking place in the vibrant city of Sao Paulo, a group of women interested in Open Data and Open Mapping, decided to gather and to start a discussion to make OpenStreetMap more integrate and increase the female presence. According to some statistics from VGI only 3% of all editions is made from women in the community. Having the largest data base in the world with not enough diverse groups will give not enough data and will be representing only one reality.

Geochicas event in Sao Paulo, one day before SOTM LatAm Thanks to companies engaged and interested in the community such as Mapbox, Mapillary and Telenav who sponsored the First #GeoChicas event in Sao Paulo we are planning to invite more women involved in other initiatives to get to know OpenStreetMap and use it in their projects. Having examples of how different regions of the world are changing lives thanks to the presence of Open Mapping is something we will need to continue sharing to create more awareness about the benefits. In the #GeoChicas event it was discussed how we wanted to lead the future efforts and engage the people attending the Conference “The role and participation of women in the OSM community” taking place in SOTM LatAm #GeoChicas in State of the Map LatAm One of the first steps is creating a communication channel and start developing mapping projects that will benefit women in vulnerable situations, #OSMintegra will be how you can identify these projects that will be shared in different social media and formal OSM channels. #OSMintegra initiative The next important event with Open Source projects is CubaConference, in this event we will impulse to have more women giving conferences and share their projects. A permanent scholarship program is also under discussion so we can help in different events around the globe sending female presence.

This is just the beginning but we can tell you that we are already making progress in this project.

Wait for more news from Mapeadora, SeleneYang and more #GeoChicas.

To be continued…

///Versión en Español///

La semana pasada el día 24 de noviembre, un día antes de comenzar el 2º State of the Map LatAm (# SOTMlatam2016) que tuvo lugar en la ciudad de Sao Paulo, un grupo de mujeres interesadas en Open Data y Open Mapping decidió reunirse e iniciar un discusión para hacer OpenStreetMap más integrado y aumentar la presencia femenina. Según algunas estadísticas de VGI sólo el 3% de todas las ediciones se hace por mujeres en la comunidad OpenStreetMap. Al ser la base de datos más grande del mundo si no se cuenta con suficiente diversidad de grupos no dará suficientes datos y estará representando solamente una realidad.

Gracias a empresas comprometidas e interesadas en la comunidad como Mapbox, Mapillary and Telenav que patrocinaron el primer evento #GeoChicas en Sao Paulo, estamos planeando invitar a más mujeres involucradas en otras iniciativas para conocer OpenStreetMap y usarlo en sus proyectos. Tener ejemplos de cómo las diferentes regiones del mundo están cambiando vidas gracias a la presencia de Open Mapping, esto es algo que tendremos que seguir compartiendo para crear más conciencia sobre los beneficios que genera.

En el evento #GeoChicas se discutió cómo queríamos dirigir futuros esfuerzos e involucrar a las personas que iban a asistir a la conferencia "El rol y la participación de las mujeres en la comunidad OSM" que tuvo lugar en SOTM LatAm.

Uno de los primeros pasos es crear un canal de comunicación y empezar a desarrollar proyectos de mapeo que puedan beneficiar a mujeres en situaciones vulnerables, #OSMintegra será la manera de identificar estos proyectos que serán compartidos en diferentes redes sociales y canales formales de OSM.

El próximo evento importante con proyectos Open Source es CubaConference, en este evento impulsaremos que se tenga un mayor número de mujeres dando conferencias y compartiendo sus proyectos. Un programa permanente de becas también está en discusión para que podamos ayudar a que asistan más mujeres a diferentes eventos alrededor del mundo. Esto es sólo el comienzo, pero podemos decirles que ya estamos avanzando en el proyecto.

Esperen pronto más noticias de Mapeadora, SeleneYang y muchas #GeoChicas más.

Continuará…

Phoenix Farm (Née Church Farm) Discovered

Posted by alexkemp on 1 December 2016 in English (English)

Having discovered that the part of Gedling south & east of Mapperley Golf Course that I am currently mapping is called Phoenix Farm Estate (not true, see below), I've wanted to know where that farm is, and have finally found it, with bonus extras.

Thanks to a post in nottstalgia.com I located Phoenix Farm on Arnold Road opposite the junction with Jessops Lane.

The farm supplies a surprising connection for Gedling with JRR Tolkein and his most famous writing (“Lord of the Rings”) - see the BBC website, although the link to Andrew H Morton's talk is defunct. The farm was bought by his Aunt Jane Neave in 1911; it was called Lamb’s Farm in a Tolkein drawing (below) (named after the previous farmer) although was called “Church Farm” at sale. The farm was close to Gedling Church (a long-range view is here), but Aunt Jane swiftly changed the name to Phoenix Farm. It is said to have been demolished in 1954. I still do not know why Phoenix Farm Estate was named after the farm.

Lamb's Farm

Contrition

I often think that ‘Contrition’ should be my middle name.

Having discovered a local government map of Nottingham Electoral Wards it has come home to me that, whilst the Estate is probably correctly called Phoenix Farm Estate, that is more likely to be due to it also being the name of the Electoral Ward that it constitutes. There's not a lot wrong with this, since the Porchester Gardens neighbourhood is largely built upon the Electoral Ward of the same name. However, there is another problem:

The Phoenix Farm Estate electoral ward begins at the other side to the Sherwood Academy School from which I've currently been working (I've currently been working in St James Ward, not Phoenix). Ah well.

OpenStreetMap training at first all-women university chapter of YouthMappers

Posted by Ataur Rahman Shaheen on 1 December 2016 in English (English)

Asian University for Women, situated at Chittagong in Bangladesh, is the first and so far only all women's university chapter of YouthMappers. AUW is an international university. This university and Texas Tech University, USA organized a training and mapathon on OpenStreetMap on 26 november 2016.

I am Ataur Rahman Shaheen, a youth mapper form Dhaka College YouthMappers chapter. I’m enrolled as honors in statistics at Dhaka College. GIS and RS Data Mgt specialist Ahasanul Hoque gave the opportunity to me and Tasnia Ahmed, another mapper from Independent University of Bangladesh to assist him in this training.

Due to final examinations the training was held for one day. 120 participants applied for the training and also attended the opening ceremony. Due to space limitation, the organizer selected only 25 participants. They will arrange another training in February of 2017.

The training schedule was divided in 4 sessions.

  1. Opening ceremony, introduced to OpenStreetMap and YouthMappers
  2. Signup in OSM and editing with iD editor
  3. Editing with JOSM and mapathon
  4. Certificate giving and closing ceremony

At the end of the event, Rosie Bateson, Dean of Faculty, gave certificates to the participants. She was so much thankful to Ahasanul Hoque for giving his valuable time and effort to this event and YouthMappers chapter of this university. She said:

"Thank you, most warmly, for connecting with us and sharing such a wonderful experience with our students. I ... could feel the excitement and joy of all the students who took part in the workshop."

Participant and President of AUW YouthMappers, Paromita Basak, gave her full effort and did very hard work for this event. Dr. Harunur Rashid, teacher of this university and Ms Fatema Patel, CDIP staff also give their full support and help to makes this event successful.

One of the most interesting parts of this event was Iftekhar Chowdhury, one of the lecturer of this university and Ms Patel was participating in this training. Its shows that not only student but also teachers are interested in learning more about mapping. It’s a very good sign for OpenStreetMap. By those people's interest, efforts and positive spirit, OpenStreenMap will go forward successfully and the world will be more beautiful by mapping.

Clean up the "fixme's" around you!

Posted by marczoutendijk on 30 November 2016 in English (English)

The fixme=* tag is often used to give other mappers an indication that something needs more research (or it is a "note to self") .
All too often it stays at that point and no one ever cares any more about such a request for improvement. I found out that roughly more than half of the fixme's is at least 2 years old.

I wrote a simple overpass query with some stylesheets attached which shows the text of the fixme immediately on the map.
Click on the link above, locate the map to your neighbourhood and hit the run button.
Is there something you can fix? Please do so and remove the "fixme"

For the centre of London, this is the result:

The overpass query searches for nodes with a fixme=, but you can easily change it to finding ways instead.
And if you want to locate all note= tagging, simply replace "fixme" with "note" in the script.

Street Art

Posted by alexkemp on 30 November 2016 in English (English)

Continuing to work my way through the Phoenix Farm Estate today, catching up in late-afternoon, with a late-Autumn sun low on the horizon at England's high latitude & damn cold, on houses missed on Stanhope Road. And yes, it turns out that there used to be a “Phoenix Farm”, though I have zero hard information on that to date.

Regular readers will realise that I constantly seek to alleviate the boredom of collecting endless lists of house numbers by spotting & photographing good examples of art on the houses that I pass ([1] [2] [3] [4] [5] [6] [7] [8]). Here is the latest: –

Mapping my home town : Gobichettipalayam

Posted by Fa7C0N on 30 November 2016 in English (English)

Gobichettipalayam is the second largest urban city in Erode district, Tamilnadu, India. It is known for the green rice fields, because of that many Tamil movies were shot here. It is in human nature to start any task from a place you already know, since I was born and brought up in this town I started my mapping here.

Quality of map before mapping:

Alt most of the roads were traced

When I started mapping most of the roads in Northern part of my town was already mapped, but some roads are named wrong. In case of POIs, there is little to no information on the map and most of the schools, Banks, Petrol pumps, community centres were not mapped. So I planned to proceed by matching the road density in the southern part of my town to the northern part and then concentrate on adding the POIs.

Things I mapped:

  1. I started by adding major and minor roads in the southern part of my town with the help of OpenStreetMap wiki for tags while correcting some road names in the northern part.

  2. Then I mapped POIs like Banks, ATMs, Schools, community centers, government offices, petrol pumps, Department stores etc., that I am sure of its location.

  3. After this I moved on to adding addition informations like bridges, bus stops and farmlands.

Quality of map after mapping:

Future plans:

  1. Adding road names.

  2. Map the missing buildings along with addresses.

  3. Add all the missing POIs.

Continued Work Around Our Hill

Posted by DesertTrip on 30 November 2016 in English (English)

I found another misplaced overlay of streets in the wrong area and deleted them. Corrected names of streets, deleted non-existent streets and tomorrow will drive around to confirm streets (and their order) before doing those such as the little courts off Cedral.

Weather Underground (aka Wunderground) wrote me today to confirm that they did just recently switch to using OpenStreetMaps for their personal weather station maps. When I am done cleaning up my area, I will go across the big road and clean-up the area for the 3rd weather station in our area.

Oh yeah!! Once I get the confirmation of our hill name from USGS, I will be adding it's name as well. We sent the name proposal to the USGS in 2014. It has since been sent to our state, then to our county, back to the state (all approved) and is just waiting for it's finalization at the federal level. I was told it should be finalized within the next 30 days. Our nameless hill (which is a distinguishable landmark from afar) will finally have a name. I can't wait! That will be fun to be able to enter. Kind of like the dessert after all this road clean-up.

Raster map tiles for Mapillary traces

Posted by Peter Bremer on 29 November 2016 in English (English)

Today, Mapillary released a set of online raster tiles that show all traces (and if you zoom in enough, all individual photo locations). The tiles are transparent PNGs, and can be used on top of other map layers.

The tileset address is https://d6a1v2w10ny40.cloudfront.net/v0.1/{z}/{x}/{y}.png

Note that various mapping software use different formatting for the x, y and z parameters. For example, OsmAnd uses {0}/{1}/{2}.

A demo page is available at http://mm.mapillary.io/raster_tiles.html

For more information, see this Mapillary GitHub issue. Also for reporting problems with the tileset, please use their GitHub repository.

OsmAnd

Here are some step-by-step instructions to add the tileset to OsmAnd. This way you can have a map showing all Mapillary traces with you on your phone, even offline if you cache the tiles before the trip.

  1. Go into "Configure map" (either from the menu, or from the globe icon).
  2. Select "Map source".
  3. Select "Define/Edit" to define a new map layer.
  4. Name it something like "Mapillary traces", and as URL enter "https://d6a1v2w10ny40.cloudfront.net/v0.1/{0}/{1}/{2}.png".
  5. Click "Save" to save the new map.
  6. Now, back in the "Configure map" screen, select your new map as the "Overlay map", and select an opaque map as the "Map source".

My Area Needed a Lot of Work

Posted by DesertTrip on 29 November 2016 in English (English)

It appears people are using some overlay and just copying it. I live here. They are wrong. There was literally 4 or 5 duplicates of our roads all within a mile or two. Some going east-west and some north-south. Some even diagonally through houses! Several duplicates went straight through mountains. MANY roads were misnamed.

I do hope that people double check before editing in the future.

Go look at what the county GIS maps show!!! Go look at your own street signs. Just don't trust the overlay here. It is WRONG.

I still have many many hours of work to do on my area. This is NUTS.

Towers and Masts

Posted by BushmanK on 29 November 2016 in English (English)

Browsing through the issues at Openstreetmap-carto (also known as OSM Standard style or "Mapnik" style) tracker on GitHub, I came across several issues, both open and closed, touching the topic of rendering vertical man-made structures such as poles, masts, and towers.

Communication engineering was my thing for awhile, so it always strikes me when at least two of these terms - mast and tower - are used in an uncertain manner. In one of the discussions on GitHub, the difference between masts and towers was called "philosophical". Actually, there is no philosophy (at least if you don't look at wrong and misleading examples in OSM Wiki). Because of that, I've added an engineering definition to pages of man_made=tower and man_made=mast both in English and Russian because what is in the first section of those pages makes zero sense and contradicts the basic principles of tagging, because it uses comparative terms such as "bigger" and "smaller" to distinguish between these structures. Tags tower:construction=guyed* are obviously redundant because if you need that, it means that object must be tagged as a mast, not as a tower.

I didn't want to rewrite the whole "definition" without discussing it, while I don't really believe that discussion could be successful, so I just added clear definition in case if someone would prefer it. Just for the reference:

Mast is a vertical man-made structure, supported by the guy lines and the anchoring system.

Tower is a vertical free-standing man-made structure, supported by its own foundation only.

(Anyone can find it even in Wikipedia, so it makes me wondering, how ignorant an author of these OSM Wiki articles was to write that.)

And it doesn't matter, that some contractors (and regular people after them) calling cellular communication towers "masts". It is not only wrong as it is to use "transistor" to call a radio receiver or "Xerox" to call a copy machine (which is common in some languages), but it makes it impossible to actually distinguish masts from towers for mapping purposes.

So, getting back to rendering, both "inverted T" and "inverted Y" are completely appropriate for tower symbols. Inverted T looks like a tower with a single stem or column, standing on its foundation, tower:construction=freestanding. Inverted Y looks more like a rough outline of a steel lattice tower (more strokes could be added to make it look fancier), tower:construction=lattice.

Masts are a bit more tricky, but just a bit. The most obvious symbol is an "inverted bird foot" symbol, similar to inverted Y with the central stroke, extended all the way to the bottom. It also looks like an inverted antenna symbol used for circuit diagrams. Central stroke represents the mast itself, diagonal strokes represent guy lines.

As a bottom line, rendering of masts and towers is not solely a question of style and preferred icons, it's also a question of using proper definitions. If definitions will get clarified one day, no philosophy will be involved in rendering and tagging anymore. (Personally, I really doubt that it will happen.)

Added from comments: These tags currently do not have "OSM-specific meaning", they are completely mixed into one mess - it is technically impossible to be sure if an object, tagged with man_made=mast is a mast and vice versa. So, changing anything can't do any harm, because it can't be messed up more than it currently is.

People are arguing about that only because almost every person has an own tradition of tagging and thinks that all others have a similar one. But it's not true - different objects are tagged similarly by different people as well as similar objects are tagged differently by them. Belief, that there is any global consistency in tagging masts and towers is just a fallacy.

Good Garden Sheds

Posted by alexkemp on 28 November 2016 in English (English)

The chap that I saw on Phoenix Farm Estate yesterday (Sunday 27 November) could not believe that I thought that his shed was worth a photo. My reasons were simple: partly it was the quality of the build: Google StreetView is October 2014 & shows a very nondescript garage, whilst the modern shed+garage is very smart. However, the reason that clinched it for me was the name that he had put upon the door of the shed next to the garage:

“The Man Cave”

Good Gardens

Posted by alexkemp on 28 November 2016 in English (English)

There are some gardens that I come across whilst mapping that simply cry out to be featured in these Diary pages. There are two today, both located on an unadopted road (the householders have to pay for all road upkeep) in Gedling that I first walked on Wednesday 23 November on a truly dreadful day. The rain was interfering with the smartphone's capacitative action, so I went back on last Sunday 27 November.

The first garden below is included simply because I found it sweet (and why not?):

aaah!

The next seemed to epitomise water action. It was pouring down from above and even flowing in a culvert below, so it seemed only fair to have galleons in a pond as well:
