Hello, In JOSM I have the ability to load GPX tracks or to download gps tracks from OSM. However in both options it seems I can't get to the elevation data, like the data saved has only two dimensions. Is there a way to get height of a track node or OSM doesn't keep that sort of data in the DB (that would be pity)? asked 02 Oct '10, 19:19  ivanatora edited 03 Oct '10, 11:24  Andy Allan |

OSM only stores latitude, longitude, timestamp, and originating track id for GPS points in the database. However, if you download a GPX file directly, any information that was in the file when it was uploaded is available to you, and this might include elevation information. (Not all GPS devices store elevation information in the track.) Note that GPS elevation information is notoriously unprecise (it can easily be off by 100 metres) so unless the GPS had a barometric altimeter which was properly calibrated before recording the track, any elevation information that you might extract from a GPS track is next to worthless. answered 02 Oct '10, 19:28  Frederik Ramm ♦ |
I sometimes use Prune to have a look at the elevation data of a gpx-track - especially to find the location of mountain passes... answered 03 Oct '10, 12:54  katpatuka |
