We have a bunch of recorded workout traces from runners, as array of GPS coordinates. Now we want to know the surfaces the runners runned on (asphalt, forest way, etc). As I am very new to OSM, I want to ask how this would be possible? I found that the data should be available in some metadata (key:surface). Is there a service query call to get this information? And, as a next step, is it possible for self hosting an overpass instance for annotating a bigger amount of such traces, preferably directly without remote call for performance reasons?

Thanks a lot

@aseerel4c26, this is exactly what I need. @andy-mackey, yes the question was about data use.

Thanks a lot guys!

For the start:

Some streets/paths in our data have a surface tag. Coverage of the surface meta data will vary very much across regions (some may have 0% and some nearly to 100%). Example querys with map visualization: or . As far as I know you could query for the closest street (closest to your coordinate point) with overpass (I do not know the details) and get its surface value.

Please have a look at and .

Selfhosting overpass is possible (but not simple), see .

Nearly everything is possible with OSM, because you have access to the raw data (which you do not have with, for example, google maps).

Surface may have been mapped if you are lucky. If not Bing may give a good idea, at least grass dirt and tarmac may be recognisable, gravel may be harder to see. The surface images may be a little out of date. Of course you will only be able to see the aerial images as an editor background.

as far as I understand the question it is about data use, not OSM contribution. @GarrySnail: please could you comment?
