What’s the state of photo georeferencing like on the Mac ? Well, it’s been lagging compared to what’s on offer for PCs, especially if you look at the latest version of Picasa, but now there’s a catch-up effort under way. Craig Stanton has been working on iPhotoToGoogleEarth, a plugin that exports iPhoto photos with EXIF coordinate metadata to KML. It’s still in beta, and doesn’t yet work on Intel Macs, but do give this free software a try and help with feedback.
How do you attach EXIF coordinate metadata to photos using the Mac in the first place? Craig recommends GPS Photo Linker, another free application which takes time-coded GPX data and marries it with your photos’ time-coded EXIF data.
For getting GPX data off GPS devices, try LoadMyTracks, a wonderfully simple yet effective free application for importing GPX tracks onto your Mac. (It imports tracks as KML as well.)
If you need more advanced support for specific GPS devices, MacGPS Pro 6 does that, and a lot more besides ($50).
