Thanks for the infos. I didn't know about CRS, although I could have guessed that it wouldn't make sense to specify meters when GPX files contain data in latitude + longitude, ie. degrees. I used 0,05 by trial and error. -- View this message in context:

Hello Archie's Campings* offers a pretty thorough list of campsites in Europe. Problem is, files are only country-size, so the number of waypoints is overwhelming (Here's the UK for instance**). To plan bike tours, I'd like to… 1) import a trace from a GPX file, 2) import Archie's list for
