Hello ! I have a gpx file with tracks of 4 days. The tracks cover an area of 20 km2 approx. There are several roads, that have been covered several times during the trip. So you can see 4 different tracks on the same road (not exactly the same). Is it possible to convert the gpx to a Openstreetmap by eliminating all these multiple tracks automatically ? asked 29 Apr '16, 18:01 Brentener Luc aseerel4c26 ♦ |
If you have traces of an area that is unmapped or an area that appears to be incorrect the best action is to upload them. The traces can then be viewed with one of the editors such as Id, JOSM or Potlatch2 and then the roads ( in your case) or tracks, paths or even rivers ( if recorded by boat) can be drawn in, and names and other tags can be added. THE automatic method is not a good idea as you will have noticed there will be some bits of trace that are incorrect. Traces are also needed when checking Bing alignment.

Don't know about Potlatch2 as I don't use it.

Using multiple traces to align Bing and to average a road or path works best.(in my opinion). We can only do this if we have multiple traces and or others upload their traces as public, so we can all use them to get better results.

It is possible to automatically convert the tracks to a OSM way, but not advisable, because manual judgement generates better results here. This description is for JOSM, but it works quite similar for other editors like P2 or iD.

So far I found only two ways to calculate an average of several GPX files with often questionable results and quite cumbersome to set up. answered 29 May '16, 18:37 malenki |
