However since I'm at OSCON I'm doing more than the usual amount of blogging, so Matt's post immediately tempted me to brush off a bunch of geotagging links which have been sitting in my edit queue for a month or more, in some cases anyway, here goes...
The first stop for anyone thinking about geotagging has to be the excellent MAKE magazine HOW TO which explains how to integrate Flickr, Mappr and Google Earth with GPS data.
Integration with Google Earth is certainly the way to go, for instance the thing that started Matt thinking about his new KML project was the integration of Google Sightseeing with Google Earth.
