Pyrenees Mountain Range Trail

Posted by sapphire2109 on 5 March 2018 in English (English)


There's a cycle route that passes under the roundabout near the Pic du Jer roundabout, and it takes you miles deep into the Pyrenees countryside.

Open Data Day 2018

Posted by GellieA on 5 March 2018 in English (English)

As we all celebrate Open Data Day 2018, mapping enthusiasts and volunteers gathered and held events all over the world to celebrate this event. I had the chance to attend an event in San Juan, PH to volunteer and give a talk about features of OpenStreetMap. Open Data had been very useful in all aspects and the progress in its objective in mapping the whole world and providing this data for all users had been evident over the years. Beginner workshop on OSM editing using iD-editor The event had been a venue to meet other mappers and to share existing developments in Open Data, which are included in the workshops as well as different projects and efforts made by volunteers through the lightning talks. Beginner workshop on OSM editing using iD-editor I had a chance to help in assisting a workshop for beginners on iD-editor and HOT OSM Tasking Manager. So glad to have shared insights with them, and to discuss interest in maximizing the use of Open Data in their respective fields.

Bad Weather = Bad Imagery

Posted by apm-wa on 4 March 2018 in English (English)

March 1-2 I traveled to Yoloten and Mary, and passed through Tejen, and tried to collect ground-level Mapillary imagery...during and after a rain storm (unusual in arid Turkmenistan, but not unknown in winter). I must apologize for the poor quality imagery. It was just too dark and gloomy. I collected some useful data and have added information to the maps of Yoloten, Mary, and Tejen (including Tejen's only hotel, which charges 6 manat or $1.71 per night). Nonetheless some of the imagery is less than marginal. Sorry! At least I added some street names to these towns, as well as some major POIs.

Today Ann and I cruised the former vilage of Gokje, now officially a neighborhood of Ashgabat since it was annexed, and collected street names, POIs, and fresh GPS traces for streets that have been created in the past year or so. Some streets had absolutely no signage at all. Not sure how we'll find the names for them.

Issues with Japan imports

Posted by bdiscoe on 3 March 2018 in English (English)

I've run my find_small_displacements program on Japan, and found some problematic imports with a large number of densely overnoded features, here are some:

  1. Bad import of natural=wood around Fukuoka. These were tightly spaced, yet also wildly inaccurate, off by as much as 80 meters and covering lots of non-wood areas, even covering motorways. I've reduced most of them, and aligned a few areas, but there's lots more to align. The original upload was in 2010 with changesets like this one.

  2. Bad waterways, especially in Hokkaido and Kyushu, but also across the country; these are not just overnoded but also overtagged, consider this little stream near Taketa, Ōita:

  • KSJ2:COP_label=1級指定区間
  • KSJ2:DFD=流下方向不明
  • KSJ2:LOC=c03671
  • KSJ2:RIC=8909180118
  • KSJ2:RIN=軸丸川
  • KSJ2:WSC=890918
  • KSJ2:curve_id=c03671
  • KSJ2:filename=W05-07_44.xml
  • KSJ2:river_id=gb02_03671
  • layer=-1
  • name:ja=軸丸川
  • name=軸丸川
  • note:ja=国土数値情報(河川データ)平成18年国土交通省
  • note=National-Land Numerical Information (River) 2006, MLIT Japan
  • source=KSJ2
  • source_ref=
  • waterway=river


Issues with this little waterway:

  • Poorly aligned; off by 20-60 meters in all directions.
  • A large number of tags that belong on the changeset, not the feature; to its credit; this wasn't a practice back in 2010 when it was imported.
  • Overnoding, using 1085 nodes for what is well represented by 40 nodes.
  • It's tagged "river", but is clearly a small stream.
  • "layer=-1" for every single waterway.

Also somewhat alarming, JOSM does not show all the tags (!?), the "KSJ2:" tags are present on the feature but do not appear in JOSM's GUI. I could not find any option in JOSM to make these key/values show up! Perhaps a JOSM expert could weigh in, or I should file a ticket.

The return of the OSM rank table

Posted by bdiscoe on 3 March 2018 in English (English)

To follow up from my previous post, I did some further work on generating and putting online a table of OSM node/way ranks table

The data that's there right now is from today (2018-03-01) and the deltas are vs. 2 weeks ago (2018-02-12).

Standard disclaimer: Last-modified-rank is only vaguely related to contribution, there is no way at all to measure actual quality or value of contribution across users, because it's subjective, and users are very different from each other. However, this table can be very useful for an individual mapper to see how their amount of contribution changes over time, and to identify, for example, accounts that are moving up rapidly which usually indicates they are doing an import. Similarly, if your rank moves down, it can mean that someone (correctly or not) has modified or deleted your mapping work.

For those curious about the technical mess that's currently involved, here is what I did:

  1. Download of the weekly planet file from Planet OSM (39 GB), this takes around 12 hours.
  2. Running a small Linux C++ app that uses Osmium to parse the pbf and generate a CSV of users along with number of nodes and ways that they are the last modifier of.
  3. On Windows, running SQLiteStudio to ingest that CSV as a table in a database.
  4. Run a C++ app that uses SQLite to query the database and generate the HTML output.
  5. FTP that HTML up to a server.

Custom Area (Orphanage grounds)

OSM Scout Server, version 1.4

Posted by rinigus on 28 February 2018 in English (English)

After more than a year of development and 38 releases, I would like to give an update on the status of OSM Scout Server. The server is targeting mobile Linux devices as a drop-in replacement for online map services providing map tiles, search, and routing. As a result, an offline operation is possible if the device has a server and map client programs installed and running. Since its tailored towards mobile devices, the server has been successfully used on devices with as little as 1-2 GB of RAM.

At present, the server can be used to provide:

  • vector or raster tiles for other applications;
  • search for locations and free text search;
  • search for POIs next to a reference area;
  • calculating routes between given sequence of points.

User's guide is available at that describes how to set it up for Sailfish OS.

While started as a wrapper to libosmscout, it now incorporates several other backends:

To use the server, you have to start it and configure the client to access it. With the help of the users, we have setup the distribution of maps in relevant formats that can be downloaded to your device. So, usage is rather simple: through server-provided GUI, users can select areas they are interested in, download, update, or remove them as needed. During the normal usage, server GUI is invisible and the server is started automatically via systemd-provided socket activation when user's map client tries to access it. As a result, you have ability to use offline the map clients that are developed for online operation. It allows also to use the same offline maps in multiple applications, a strategy that has been successfully implemented by several applications in Sailfish OS.

Most, if not all users, are coming from Sailfish OS, but it should be relatively easy to adapt the server to any Linux. Already now it can be used from the command line, although the interface could use some adaptations to simplify management of the maps. However, taking into account that the server if written in Qt (C++ and QML), writing OS-specific GUI would probably require relatively small amount of time if done through QML.

Major Changes in Central Park Mall Jakarta

Posted by Reinhart Previano on 24 February 2018 in English (English)

Changeset details:

The Central Park Mall is one of the popular shopping malls in West Jakarta, Indonesia. It is also inspired by the design of the Central Park in New York City.

This mall has a park for visitors to walk around, called the Tribeca Park. Aside from that, this mall is also connected to the Tribeca (a 2-storey section of Central Park Mall consisting of several restaurants) and Neo Soho (the shopping mall below the new Soho apartment near to Central Park). These malls are owned by the same developer, PT. Agung Podomoro Land.

In this changeset I added the new Tribeca (mall) section at the other side of Tribeca Park, including the skybridge connecting Tribeca ↔️ Central Park ↔️ Neo Soho. I also added more details on Tribeca Park itself, including added new footpaths, restaurants, ponds, fountains and a new escalator. There's 1 more pond left unmapped, as I need to re-check on site for the accuracy of its position.

So far, here's the changes I made to this shopping mall. As of now, there might be some mistakes in my changes to, which I will fix it later.



And here's how my work is compared with Google Maps (as of 25 February 2018):

How should I tag a surf shop/cafe

Posted by ConsEbt on 24 February 2018 in English (English)

Hi everybody, I'm looking for suggestions to improve the tagging of the Surf House Dubai which I have [](added today).

Now I did add some tags to the surf shop as suggested by the wiki however I'd like to have some comments.

  • how should sale and renting of surf, wake and stand up paddling boards be tagged?
  • how to add the surf school?
  • how to add the surf shop - they sell board, parts, tee shirts, shorts, sunglasses, sunscreen etc.
  • how to add Yoga classes

What are your suggestions?

OpenStreetMap and Strava in Christchurch

Posted by Adam Heinz on 24 February 2018 in English (English)

Lots of global companies use OpenStreetMap. Take Strava, for example:

The Strava Global Heat map shows cycling activity around the world, including Christchurch. ( ).

The road lines are based on OpenStreetMap ( ).

By improving OpenStreetMap we can ensure that our fellow citizens are making decisions based on accurate information provided through 3rd-party providers.

An OSM Logo for Translation Projects

Posted by dcapillae on 23 February 2018 in English (English)

Some time ago, the OSM community in Spain had a discussion to add a country template and choose a new image for our wiki page on the OSM Wiki.

The OSM community in Spain has been using an OSM logo with the letters "ES". This logo was the same one that we were using in the WikiProject Spanish translation.

The Spanish-speaking OSM community in the world is not limited to Spain. Therefore, to avoid confusion between OSM Spain and OSM "in Spanish", we have changed the logo for this one, a simple and more generic logo which can be used in your OSM translation projects and wikiprojects.

Surau and parking in building enhancement suggestion

Posted by SNN95 on 23 February 2018 in English (English)

Whenever I want to edit this kind of religious POI, I found that only mosque option available. There are different for each of them. Mosque for big one and surau for small one.

I want to emphasize the surau. Surau is a small and can include in every buildings in malaysia. That's the rule for Malaysians or any investors that want to build one, they must include at least one surau.

So I want to edit to include surau in a building but there is none in the option or tag.

And other tag option like parking, ATMs, etc that can be include in a building. Maybe I can use the point but that not very convenient for a multilevel building.

This is just my rant for this subject. And if you think I missed the features option included in editor, feel free to tell me. Maybe I'm not explore them enough yet.

Why I need OpenStreetMap

Posted by SomeoneElse on 22 February 2018 in English (English)

(written in response to the discussions here and elsewhere, prompted by this blog post, which was in itself presumably prompted by this HN item)

Yesterday was a nice day, so I decided to walk from Derby to Alfreton (roughly here). The criteria were pretty simple:

  • No muddy paths
  • Only roads with footpaths alongside (sidewalks in OSM terms), or if necessary, grass verges (or very minor roads)
  • Somewhere to stop for something decent to drink and a bite to eat.

Ignoring "automatic routing" altogether, what map provider in the UK has that data? OSM does (at least in the area that I'm interested in). Google sort-of does - I'm sticking to roads here, and via their StreetView I can see that e.g. Codnor Denby Lane does have somewhere to safely walk, but it's not really practical to "virtually walk" an entire route in Google's StreetView to check it before setting off. HERE has some aerial imagery but not with enough detail. The UK's Ordnance Survey surely has most of the data, but getting at it is hard (even if you pay them money). The small map on this page can be zoomed in to hint at sidewalk info, but neither the buyable OS Explorer map (which I have a copy of) nor this page which I presume is based on OS OpenData, do. Bing can show basic road info and their own or OS Explorer's map style, but no "is this walkable" information.

With regard to POI data, Google was (until yesterday) the only one that had the correct name for this pub, and does link through to food and beer details (even CAMRA, usually the go-to guide for this sort of thing, are out of date). However, there's no differentiation on the map beyond a "place that serves food" icon and a mousover blurb ("family friendly chain pub and restaurant").

So am I missing something - is there anyone out there with this level of data that's available in an accessible format, other than OSM?

How are you "supposed" to map landuse?

Posted by Nikola Bura on 22 February 2018 in English (English)

I know exists, but I've got a separate question...

Basically, is it intended for landuse to eventually cover the whole entire globe, so that every available spot of land is marked as either residential, commercial, parkland, or water, etc? Or should landuse only cover a few areas, while the vast majority of the map is left as "standard" empty grey?

The European countries seem to have a lot more landuse cover than the US, so should I use them as an example?

The "residential" landuse is what's confusing me here, in particular, because I could mark vast swaths of the map (think apartment blocks, suburban neighborhoods) as "residential", or I could leave them unmarked. Same goes for things like "forest" and "farmland"... should all woods and fields be marked with landuse, or just left empty? Not sure what the usual approach is.

Addresses in southern Platte County, Missouri

Posted by farallon on 19 February 2018 in English (English)

As inspired by Angela Morley's post on the 15th of February, I will be attempting to systematically fill in as many addresses as I can in areas of southern Platte County, MO, including areas such as Parkville, Riverside, and so on. I'll be starting with residential, in the areas south of MO-45, and working outward from there as I can. Wish me luck!

How to map buildings within a building?

Posted by howdystranger on 19 February 2018 in English (English)

Hi all,

Hoping for some guidance.

Here's the area I'm looking at.

It's a hospital in my city. It's a series of buildings which are connected together. What is the best way to label the individual buildings? Previously a mapper had put individual buildings on top of the underlying buildings but that doesn't seem great.

Many thanks
