This should not be named Planet.gpx since it is not a .gpx file. How about PlanetPoints.csv? --Schnitzelinmypocket 10:27, 3 April 2012 (BST)
- The actual download is called 'simple-gps-points-120312.txt.xz'. It is here that some thought has been put into a filename with a correct extension.
- I suppose this thing (the overall service) has been codenamed 'planet.gps', just as a nickname which fits nicely with the other wiki page 'planet.osm'.
- Also bear in mind that this service may be altered / extended in future. I suppose one thing which might be made available is more raw access to uploaded GPX files (But I'm not in a position to make any promises).
