Average highway node distance between 2 points in OpenStreetMap - September 2015 12 days ago

I think that a line plot as you used is not the best way to visualize your data. Such diagrams are good for plotting a variable y which is a function of a variable x. A set of bar diagrams (one per road class with one bar per continent) would be better.

You have the data. Could you just plot it again?

Mappen mit dem Deutschlandpass – Schlafplätze bei Mappern gesucht 28 days ago

Hallo martinum4,

danke für dein Angebot. Aber unsere Tour ist schon seit dem 24. August vorbei.

Wieder Garmin about 1 month ago

Hallo zut,

verrätst du uns noch, ob es sich um einen Vista HCx oder Legend HCx handelt? Seit wann war er in Betrieb?

Viele Grüße vom Wochennotizteam


New road style for the Default map style - the full version about 2 months ago

Hi Mateusz,

I really like your improvements, especially your huge use of service=* on railway tracks.

Best regards


Stammtische und Berlin im Detail 2 months ago

Wenn ihr derzeit (d.h. seit ihr im Resonanz seid) durchschnittlich nur auf gut 6 Besucher pro Stammtisch kommt, ist das für die Größe Berlins eigentlich erschreckend wenig. Karlsruhe, das nicht mal ein Zehntel eurer Einwohner hat, hat gefühlt im Schnitt genauso viele Teilnehmer. Liegt das vielleicht daran, dass der Karlsruher Stammtisch eine Abspaltung der örtlichen LUG war? Oder liegt das daran, dass in Berlin die Wege aufgrund der Größe Berlins so weit sind, dass manchen der Weg zum Stammtisch zu weit ist?

Vielleicht schaue ich ja bei eurem nächsten Treffen vorbei.

Mapping turn lanes in OpensStreetMap 2 months ago

It is no good idea to use relations for turn lane mapping. Roads are very often touched by newbies. Newbies use iD and/or have no knowledge (iD does not help them to get it) about relations.

I hereby strongly suggest neither to use the plugin you promote nor to use relations for turn lane mapping!

Starting up again 2 months ago
  • Get offset on Bing maps sorted out.
  • Get plug in to handle .gml files available from land registry (INSPIRE index polygon data.)

Data imports must be discussed! See Import Guidelines.

  • Work out how to get more layers such as electoral boundaries , district council boundaries etc.

OSM may not be the right location for electoral boundaries.

  • Find out about adding photos to the map

New road style for the Default map style - the first version 3 months ago

I would prefer red junction names.

Is switching from blue motorways necessary? I realize that blue doesn't cleanly fit into a yellow orange red scheme, but it's unfortunate to lose a color which currently doesn't conflict.

There is already a conflict! Motorway blue looks similar to water blue.

I had a client who got rendered OSM maps (the Carto-like style of Maperitive) for printing. He asked me first to change the motorway blue to orange because it looked better.

From car driver point of view, there is less difference between a trunk and a motorway. By default, trunk have no speed limit in Germany (like motorways). The only differences are shorter curve radius and smaller lanes. That's why rendering of motorways and trunks should be similar.

New road style for the Default map style - the first version 3 months ago

I agree with your decision on rendering trams only at zoom 12+ as a railway fan (and co-developer of OpenRailwayMap). I have had a look on tram lines which go kilometres out of their city, e.g. Gotha–Tabarz.

If you go to change rendering of trams, you should also have a look at rendering of light rails (railway=light_rail). Light rails often run near roads (or between the two carriageways). Especially in Germany, we have multiple cities where light rails serve the job of trams, e.g. Stuttgart or Frankfurt (Frankfurt has two separate systems a partially over- partially underground light rail and a tram network). (trams are pink, light rails green, undergrounds blue, orange/black/brown/yellow/red are heavy railway tracks, tunnels are brighter)

Natural Atlas + OpenStreetMap 4 months ago

Your Terms of Service state:

Geographic location data (latitude, logitude coordinates) from Natural Atlas cannot be used commercially without explicit written concent from an employee of Natural Atlas. If you're interested in this data, please email *****

From my point of view "cannot be used commercially without explicit written concent" is not compatible to OpenStreetMap data license.

  1. You cannot forbid me to vectorize map data from your map.
  2. If your users place the markers based on an OpenStreetMap-based map, these positions are covered by the share-alike of Open Database License.

Der User ist kein Bot, der heißt bloß so. :-) Außerdem sollte jeder Bot auf PNs und Changeset-Kommentare reagieren oder wenigstens auf seiner Profilseite den Account seines "Kommandanten" angeben, den man dann anschreien kann.

@derFred: Ja, da hast du Recht. Ich überlege gerade bloß, ob ich das tun soll und mal wieder "in ein Wespennest stechen" [1] soll.

Trying Overpass API 6 months ago

The combination of osmconvert and osmfilter (see OSM Wiki) might be a alternative at some use cases, especially if you need data of larger regions (counties, countries, …). You can download the raw data which is the input for osmfilter and osmconvert at I suggest PBF format.

Addresses Revisited 6 months ago

I think we have more than "1/3 to 1/2" of all addresses in Germany mapped yet. There a lots of buildings without a house number (even in the official cadastre). These adjacent building ("Nebengebäude") like garages or barns often are located on the same parcel and that's why they do not have an own housenumber.

It's time to import TIGER address ranges into OSM 6 months ago

I fully agree lyx.

America still suffers from an old, bad import called TIGER which has not been fixed yet. Importing the next TIGER data set would be as effective as spraying Roundup on every American mapper (if mappers were plants).

OSM is not a data storage center for public GIS data. If someone needs addresses for the whole US, he/she should download the TIGER address data and add it to his PostGIS database. Because TIGER is public domain, this no licensing problem.

From my low level comparison with Google data in a rural town, addresses were off by 10-20 feet max. More rural areas increased the uncertainty level, but it is significantly better than literally nothing.

I believe that Google uses TIGER addresses in large part of the U.S. They might have added a random error on each address coordinate to be able to prove copyright infringement.

As I wrote at other blog posts: People map if they miss anything. If they miss no data, they do not map, i.e. nobody misses data in rural areas. I think that Frederik's classification of the U.S. OSM community is not as bad as the answer at the Talk mailing list indicate. (There are some people who neither fit in category A nor in category B)

(a) A project for hackers and couch potatoes who trawl their county web pages and other sources to look for stuff they could "upload" to OSM (because it's such a big country and nobody could possibly, yadda yadda yadda)

(b) A project for people who roll up their sleeves, travel to places of humanitarian crises, and help those in need by creating maps where the government hasn't done their job well.

(Actually) fixing the Peoria GIS import 6 months ago

If an import was a bad import like the one you describe above, it should be reverted, not repaired. If people need really a map in this area they either will reimport the data in better way (simplified geometries, better tagging) or they will map the area by on the ground survey. If there are no mappers in this town, nobody needs the data.

From my point of view, OSM is not the right place for old data. Either import up-to-date data or map it on your own! I would delete the whole data garbage.

Du hast das alles falsch verstanden.

Der Stadtplandienst mit neuer Technik und OpenStreetMap ist online 6 months ago

Endlich mal ein städtischer Stadtplan, der OSM nutzt UND einen mir noch unbekannten Kartenstil verwendet! Besonders auffällig ist, dass euer OSM-Layer keinen Hausnummern rendert und stattdessen die Namen der POIs in den Häuser (d.h. Ladengeschäfte usw.) bevorzugt.

Einen kleinen Kritikpunkt habe ich aber noch. Wenn ich ein die topographische Karte anzeige, wird als Quelle immer noch OSM unten rechts genannt. Das ist etwas unschön.
