On his voyage into the guts of Google Earth, Mark McLaren discovers that the application comes with a GPS file format converter called GPSBabel, which means it can load GPX files, the defacto GPS file standard. That will make life a lot easier for those with legacy data they’d like to put to use in Google Earth.

Mark also discovers a lot more about how both Maps and Earth get their data. Definitely worth a read.

[Update 00:07 UTC 2005-07-27: Here is a long list of GPX resources. And here is repository of GPX files.]
