Hello, dear OSM passionates :)

Eastern Latvia (Latgalia), and Western Russia require our work!

It would be great if you guys could help me.

Those territories are a total OSM leftover and really needs a lot of work.

What is usually wrong? A) Eastern Latvia: ROAD MISTAKES: - Roads drawn where they don't exist (or the opposite), - Non existing sharp curves, - Main dirt roads shown as single forest/field road, and the opposite. - Roads to possessions shown as main roads or not shown at all. NAMES: - Name mistakes (recently corrected, for instance, Goliševa - someone had written Golyševa), - Infrastructure main names (border checkpoints, etc.) written in other languages than Latvian as the main name (Russian or English usually that should be moved to from the name tag to name:en and name:ru, etc.)... OTHER: - Rivers, canals, etc. not drawn

B) Western Russia (Close to the border with Latvia and with Estonia): - Lots of roads haven't been drawn on OSM despite existing. Maybe they are not roads of high importance, but this work must be done as people all around the world use OSM and OSM-based GPS maps. Remember people living in those remote villages may be using that app. - Lots of lakes, forrests, etc. not drawn on the map.

You won't get bored anytime soon if you start taking care of those beautiful regions :)

Btw, I wanted to ask our Latvian users: is it possible to used as a source?

Kind regards,

OpenStreetMap Carto release v4.1.0

Posted by kocio on 30 July 2017 in English (English)

Dear all,

Today, v4.1.0 of the openstreetmap-carto stylesheet (the default stylesheet on has been released and rolled out to the servers. It might take a couple of days before all tiles show the new rendering.

Changes include

  • Malls are no longer rendered as dots (bug fix)
  • Special icon for shop=tyres
  • Airports rendering changes: removing clutter on z10 and moving name labels under the icon
  • Switching forest, scrub and quarry patterns to SVG

In this release we're also introducing Docker-based development environment, which makes it much easier to preview rendering changes before they are deployed on the servers.

Be warned that there's a change in our release plans: compatibility with v3.x series is no longer maintained from now on, so database reload is needed to keep up with current style changes. Some of them can be however backported, especially if you're using hstore-enabled database already.

Thanks to all the contributors for this release. Special thanks go to MaestroGlanz and daganzdaanda for a new icon.

A friend sent this article about CalTopo: "Your Navigation Is Outdated. Here's How to Fix It."

Posted by apm-wa on 30 July 2017 in English (English)

Interesting article came to my attention thanks to a friend--a discussion of tools and a product called CalTopo that seems rather intriguing--multilayer topographical maps of backwoods areas (I am a hiker when I can get back to the States). I'm wondering who out there in the OSM realm has experience with it, and what you think of it:

Collecting bus stops on foot

Posted by apm-wa on 30 July 2017 in English (English)

Motor vehicle traffic was banned in Ashgabat on Saturday, July 29, in an effort to promote use of bicycles. Since I have no bicycle, I walked up the median strip between the new extension of Mollanepes kocesi and Seydi kocesi in Ashgabat, and used Mapillary to geolocate the bus stops. It was a toasty 42 degrees Celsius (107 Fahrenheit) so I wore a hat and rehydrated on return. I also collected the names of all the buildings using Pocket Earth. No building numbers have appeared yet, however.

A trip to Dwasieden castle ruins

Posted by ChristianA on 29 July 2017 in English (English)

So we're on Rügen; the beatiful island on the coast of Germany. This used to be a part of DDR during the cold war. Of course there are still many things left from this period. One such thing is the Dwasieden castle. There is no english wikipedia page for it, unfortunately, but at least a short german one: Dwasieden on german wikipedia

Ruins among the trees

In short, the castle was used by the Kriegsmarine during WWII. After the war, the Red army destroyed most of the castle but used the area for military purposes. There are industrial buildings (more or less ruins) left in the area, what seems to be bunker entrances and many remnants from military and industrial activitivies. I would love to know more about it, but it seems hard to find info in english.

Second floor

Anyway, most of the buildings and roads in the area are quite well mapped, so when I arrived it seemed there was not much for me to add. However, the actual castle did not have any outline in OSM, just a single node. I did not have much time for my visit, but I traced one lap around the ruins, and walked a bit on what was left of the second floor in the southwest wing.

Section of (partly destroyed) first floor

When I got home I used the blueprint found on Wikimedia commons and tried to adjust it to my gps track, using JOSM. Unfortunately my track was not very accurate, but I tried anyway. Since the blueprint had a scale ruler on it, I could at least adjust the scale of the image fairly accurately in JOSM.

JOSM screendump

Probably someone may improve this work, but it was a very interesting visit. One could spend days there mapping things.

Hail Hydra(nt)! - GenSan edition

Posted by GOwin on 29 July 2017 in English (English)

I am visiting General Santos City for some research but, unexpectedly, we completed our tasks much earlier. I had lots of time to kill, and reached to a local university (Notre Dame of Dadiangas) and offered to conduct a workshop on FOSS/Participatory Mapping for their community. Unfortunately, because of the short notice, and their other commitments they were unable to accommodate the request.

image Diligent RAs made quick work of our tasks

Two blocks down from the university, is the headquarters of the city's Fire Department, and I decided to drop by, to say hello, hoping for some chit-chat, and maybe some data as well.

Luckily, not only did were they willing to chat, they were even willing to work and map their assets - pronto!

That same afternoon, we got to complete the map of their fire hydrant network, including the location of auxiliary companies in General Santos City :

After jamming with them, they invited me to join a planned field inspection for the following morning. I willingly accepted, and offered to demonstrate how Mapillary works, and how they may utilize them in their work flow.

Their inventory report include a description of the location, but they're not what we saw on the ground - weed covered hydrants, missing markers, or buried in concrete! Also, we had problems finding street names, and other basic information, so we had to stop a few times, asking directions from local residents.

We collected imagery using Mapillary, and used them to tag the hydrants we found.

As for me, well, I got to ride a fire truck for the first time - and even got to don a firefighter's helmet. :grinning:

Kudos to the friendly and enthusiastic crew of the General Santos City Fire Office.

My Local TIGER Review Continues

Posted by mtc on 29 July 2017 in English (English)

Today I finished verifying the TIGER data for all the roads in a neighboring town today, and I am patting myself on the virtual back. That is the second one under my belt, including my home town. I am picking away at these local roads bit by bit, and I am even making a serious dent in the nearby city.

One day last week, I made a trip to the well-mapped university town nearby, and decided to do some additional mapping there. I was shocked to discover that the vast majority of streets are still tagged TIGER:Reviewed=no , even while the university foot paths and buildings are documented in ultra-fine detail. I understand people do map the details that they find interesting, but I would have thought these interests would be built upon Main Street, at least. It is disappointing to see this vital road left unreviewed. Perhaps communicating with some local mappers would encourage further road review.

Ashgabat's 4th Microdistrict (4 Etrap)

Posted by apm-wa on 28 July 2017 in English (English)

A local resident of Ashgabat's 4th Microdistrict was kind enough to take a FieldPapers printout and mark it up to indicate with which street the buildings with numbers are associated, so that we can assign routable street addresses to the buildings. Just finished the first session of adding these data to the Ashgabat map. This resident also provided corrected boundaries for the microdistrict, so I moved them.

OpenStreetMap Awards 2017

Posted by Zverik on 28 July 2017 in English (English)

Did you know that the community voting for the OpenStreetMap Awards is open right now? We have chosen many nominees that did a great job last year, 45 of them! Not as many as the total number of active community members, but still a lot. And nine will receive the award at the Stat of the Map in August.

All nominees will be features in the series of OSM Blog posts:

Help translate the website and project descriptions to your language:

The voting closes on 16th of August. Vote now — you can change your choice at any time. Nominees would be glad to hear they are supported by hundreds of voters, so we would need at least a thousand people to vote.

Promote the Awards in your local communities, and if you are nominated, do encourage your subscribers to vote for you :) That is okay, provided you don't pay for votes or anything like that.

HOT Mapathon

Posted by Chetan_Gowda on 27 July 2017 in English (English)

Hello all, Namasthe! 🙏 We had an amazing HOT Mapathon on July 21st at Mapbox India office. We had the local OSM community along with folks who were mapping for the first time adding approximately 3000 buildings in Cambodia for Eliminate Malaria task.

The good thing about this event was that most of them knew about OpenStreetMap and very few people were new into mapping activity. At first, we introduced to OpenStreetMap, it’s data model, and good practices one should know while editing and a short demo of editing in iD editor.

Few Photos

Upendra introducing the HOT and it's objectives

Jinal Foflia helping the participant for mapping

Many of us discussed about ongoing mapping activities in Africa with more emphasis on FGM and Malaria issues and how non profit organisations are utilising the data that people produce to save many lives. Also, we've discussed about upcoming State of the Maps in Japan, US and Nepal. Some of the questions they asked are like, how data produced by many people been validated? who will take care of ground truth? and what is the community capacity right now? and so on. Hope we cleared all of them!

We hope to have many more events in the future with the community and help for humanitarian purposes.

Best, Chetan

Public Transport Mapping, why do we add the stop details several times over?

Posted by Polyglot on 27 July 2017 in English (English)

When we started mapping public transport stops, some people insisted on mapping them on nodes next to the way, others thought the right way to do it, was to add them as nodes being part of the highway, thereby losing the information on which side of the road the bus stop was.

Then somebody came by with the idea to unite both ways of mapping. In itself that sounds great. But where do we add the details then? On both? That doesn't really make sense. It's a maintenance nightmare.

So we still have some people adding the stops as stop_position nodes on the highways and others mapping them as isolated nodes next the ways as public_transport=platform. But of course a node is not a platform, so others map those as ways and areas. Nothing wrong with that, but why do we need to add all the details to these ways?

For some reason it was decided that both these stop_postion nodes and the platform ways/nodes need to be added over and over again to the route relations. These route relations represent each and every variation of the public transport lines, so there are thousands of them. Another maintenance nightmare.

Why can't we have a node next to the way, with all the relevant details and add those nodes to the route relations, then followed by a continuous string of ways? The node gets tagged public_transport=platform/highway=bus_stop.

The node isn't always representing an actual platform. If there is a platform, nothing wrong with representing it as a way or an area. But there is no real need to duplicate all the details like name/ref/route_ref/zone to these ways. And there isn't really a need to add them to the route relations.

For the simplest bus stops a node next to the way public_transport=platform/highway=bus_stop is all that is needed. It contains all the relevant information and it has coordinates, which makes it convenient to compare it to data from operators.

For more completely mapped bus stops, benches and waste_baskets can be added.

If you want to make explcit where the vehicle stops, a public_transport=stop_position can be added on the highway. For the first and last stops, the way should be split there, as it's the beginning or end of the route.

But these stop_position nodes are not all that important, so no real need to map them for every stop. Also no reason why the stop details should be repeated on them and no real need to add them to the route relations. It's enough to add them to stop_area relations.

Wanderrouten im Pfälzerwald

Posted by Wegabschneider on 27 July 2017 in German (Deutsch)

Die Kartierung der Wanderrouten bzw. der Wanderwege ist dank der zahlreichen Mapper gut vorangekommen. In den Jahren sind aus lokalen Rundwegen sehr oft Themenwege geworden. Dabei sind nummerierte Wege auch entfernt worden. Zumindest auf den neuen Infotafeln. Im Gelände findet man weiterhin alte Markierungen aller Art, leider. Ein Schwachpunkt ist die Aktualität der Daten. Einmal erfasst, so lässt die Aktivität der Kartierung an den Wanderwegen nach. Es gibt zwar zwar Mapper, die sich darum kümmern, jedoch nicht so viele wie zur Zeit der Ersterfassung. Mir ist bisher nicht bekannt, dass von Gemeinden, Vereinen, Verbänden ein aktiver Beitrag zum Datenbestand stattgefunden hat.

  • paved or unpaved
  • Example: Cooper Creek Road (FS 33) and Blue Ridge Road (FS 42), in Georgia

highway = track

  • not a through road
  • unpaved
  • generally unmaintained, AWD/4WD is recommended or necessary (smoothness = very_bad, or worse)

highway = service

  • not a through road
  • paved or unpaved
  • short or medium length
