This is somewhat related to my earlier question. While using Open Street Map, is it possible to force a specific area to be cached? If it is, is it possible to force the map interface to load solely on the cached tiles(in the event internet connection isn't possible)?
An example would might be all tiles from within 5 miles of gps coordinates x and y. Afterwards, if the program doesn't have internet connectivity, it would load from the cache directory.
Thanks,
Ryan
