From Dirk Stichling:
myTracks is a geotagging and geocaching application with a convenient GPS track library. GPS tracks can be downloaded from most of the common GPS loggers, such as: Wintec WBT-201, Holux M-241 and GPSport 245, Columbus V-900, Gisteq Phototrackr and Phototrackr Lite, iBlue 747 and Sony GPS CS-1 and CS-3. The new GPS-Logger-Assistant helps configuring your device. The GPS tracks are drawn on different maps which are also available while being unconnected from the internet. The most incredible feature is the synchronization with iPhoto '09. Just select your photos or events in iPhoto, drop them to myTracks's dock icon and they will be geotagged automatically. They are available in iPhoto's Places immediately. There is nothing more to do.
