Have you considered getting data from the Open Street Map [1] database ?
Freedom for geographical data is unfortunately behind the one for
geographical software, OSM is in my opinion the best attempt at making
this more balanced. It won't provide photos though, only vectorial data.
There are tools to import those data in a postgis database, for later
processing/georeferencing. There are also a few specialized renderers
which you could use to generate static tiles, if all you need is images.
