Why not do both? We could have per dive coordinates but if those are not available use those of a dive with a location of the same name?

Similarly, I would propose to have many possible sources of coordinates: The web service, images with geotagging, .gpx GPS tracks.

I am currently playing around with some code that extracts this informations from all these types of files to add them to the .xml. For this purpose, could somebody please mail me an .xml file that already contains GPS coordinates?
