I’m just playing about with the data from a little Garmin GPS thingy I got. It saves it in an XML format (specifically, http://www.garmin.com/xmlschemas/TrainingCenterDatabasev2.xsd).
Just wondering if there was any more standard format I could convert it to, maybe something that libraries (e.g. the Google Maps API) would understand.
What you’re looking for is probably KML. Its pretty easy to use, just check it out.
