The Sony Alpha SLT-A55 made its way to me and it has a built-in GPS. Each photo is marked with its GPS coordinates, elevation and orientation. I am aware that if I upload such a photo to Picasa or other web-services like Panoramio, then I'll be able to see a map showing the location where a picture was taken.
The question is, what can I do with this locally? Meaning, on my own computer without uploading my photos anywhere. What kind of programs exist to use the location data in a meaningful or interesting way?
For my specific case, Linux and Windows software are fine (I run the latter in a VM under the former). Mac-only software won't be of any use to me.
