400,000 Mapillary Images

^^ Forgot to mention, both of those apps allow to turn off the screen during capture, which results in less battery use, less overheating, and more privacy for you.

@apm-wa, vacations are a great opportunity to take Mapillary photos! ;-)

I have also been struggling a lot with the Mapillary app before with my older phones. You might want to try alternative apps for collecting the photos, but then you must geotag and upload the photos yourself afterwards. I have had great success with DailyRoads Voyager (very stable, but limited to one photo every 5 seconds) and Hidden Camera Snapshot (now removed from the Play Store, don’t know why).

Congratulations! The world needs more photos, especially in those places where the commercial ones don’t come. 😁

OSM x GM's "glitch"

Sadly, the images all link to the default Berlin view of BBBike.org. To get the proper URL to link to, you should click the “Share” link in the bottom right, and copy the URL from there.

@d1g mapping at night/holidays sounds like a great way to be confused for a potential burglar scouting a street for victims :-)

Raster map tiles for Mapillary traces

Thanks @GITNE and @taopeng! I’ve updated my description with links to Mapillary’s GitHub repository.

Short history of name editing in MAPS.ME

And the street names in Brussels are labeled as “<French name> - <Dutch name>”. (Where it just says “ - “ in my original comment.)

Short history of name editing in MAPS.ME

Looks like the comment system ate my “<lng>” codes. Everywhere you read “name:”, it should have been “name:<lng>”.

Short history of name editing in MAPS.ME

There is one big difference between “name” and “name:". The "name" field (if my interpretation is correct!) is supposed to contain the name as it is displayed at the location, while the "name:" fields are for the names as the are actually used in various languages.

For an extreme example, if I were so creative to advertise my fantasy bookshop everywhere with it’s name written in runes, then the “name” field should contain those runes. Of course, nobody knows how to pronounce these runes, so the shop will also have a local, pronounceable name, which would be recorded in the “name:" field.

For a more practical example, in some multiple-language countries, certain names are always recorded as a combination of multiple languages. A good example are the street names in Brussels (the capital of Belgium, a Dutch & French speaking country), which are labeled as “ - ". This is what goes into the "name" field, while the "name:fr" and "name:nl" fields contain the individual names for each language.

In reality, I don’t think there is any global algorithm that can determine what should go into the “name” field.

But I do think that any “name:" field that contains the exact same string as the "name" field (as in the example Athalis gave), should just be discarded.

map styles: Default OSM vs Google Maps

I have to agree with _sev, the OpenMapSurfer style is not getting the recognition it deserves. In my opinion this style solves many of the problems listed in this discussion:

London: http://129.206.74.245/?zoom=17&lat=51.49149&lon=-0.27424&layers=B00000FFFF - At Z16 more information than GM, but more readable than OSM - At Z15 most one-way arrows are still visible, while they are gone in both OSM and GM. I’d say clearer road hierarchy even than GM, though the residential roads could have been more dimmed. - At Z13-10 more chaotic than GM, but mostly because of all the road number labels.

Rural: http://129.206.74.245/?zoom=13&lat=53.2118&lon=-1.7971&layers=B00000FFFF At Z13, OpenMapSurver is again a clear winner over both OSM and GM.

High density residential roads: http://129.206.74.245/?zoom=14&lat=4.62854&lon=-74.18337&layers=B00000FFFF Clearly better than OSM, and personally I think a bit better than GM.

Mountain map: http://129.206.74.245/?zoom=15&lat=48.77591&lon=-121.81464&layers=B00000FFFF Here, OSM is a clear winner, though OMS comes close.

High building density: http://129.206.74.245/?zoom=15&lat=-29.32611&lon=27.51527&layers=B00000FFFF Bit better than OSM, GM is much better.

Roads vs canals: http://129.206.74.245/?zoom=13&lat=51.29423&lon=3.14257&layers=B00000FFFF OMS is better than either OSM or GM.

Not purely road-related, but from Z9 and down, OSM is really terrible, both aesthetically and practically, and I think OpenMapSurfer is better than even GM: http://129.206.74.245/?zoom=7&lat=51.70458&lon=20.03954&layers=B00000FFFF (of course the capital city is clearly identifiable) http://129.206.74.245/?zoom=5&lat=53.67525&lon=17.18309&layers=B00000FFFF (a bit too busy in some countries, but still gives a clear overview)

In my opinion, just inheriting the OpenMapSurfer style fixes 90% of the problems the default OpenStreetMap style is struggling with…
