Google Earth can work off-line, when it's not connected to the net, but you only see what it has in its cache. Obviously. However, there's no way of marking out an area and saying "please cache this"; the only way seems to be to sit there patiently, dragging it back and forth.
However — the paid version can follow current location from a GPS. The GPS protocol (NMEA) is trivial. So, a couple of loops and a bit of config later, it *should* work…
I'll have to try that!
Update: Actually, it's even easier than that. Even normal Google Earth can show a tour of waypoints and import .kml files. All it takes is a little script to generate a file of evenly-spaced waypoints at 5km height and presto! it's there!
I'll put the code here later, it's Christmas Eve now... (E-mail me if I forget!)
