Preview in OS X 10.5 to support georeferenced photos
From the 300+ features announced in OS X 10.5 (courtesy of SlashGeo), one that I really like the sound of is that Preview will now recognise and make use of georeferenced digital photos – photos that have latitude and longitude incorporated in them.
GPS Metadata Support
Get real information from your photos. If your image has embedded GPS metadata, Preview will show you exactly where that perfect photo was taken. Open the Image inspector and select GPS. Preview pinpoints the location where you took the photo on a world map. From there you can even open the GPS location in Google Maps.
Of course, not many digital cameras support GPS at this point, but there are a number of ways to add lat/long information to photos when post-processing. I recently purchased a very small GPS tracker that I can mount on my camera and it generates a tracklog that can then be matched up with the timestamp in a photo to estimate where the camera was at a given point in time. I am interested in this not only for hobby photography, but also as an application during disasters using this setup for Disaster Impact Assessment and being able to easily produced georeferenced photos of damaged infrastructure for example.
