For those of you who may be interested, I recently discovered a great Android map app. Maps can be viewed either on-line, or can be downloaded (in a user-selected range of zoom levels) for viewing when away from internet access. Users can also add their own points of interest (and gps tracks, etc., if their devices are equipped with it). It's called Locus, and a free version (ad supported) that does all this is available both from Slideme and the Amazon app store. See also http://www.appbrain.com/app/locus-fr....android.locus, and http://forums.groundspeak.com/GC/ind...owtopic=267205.

On-line map sources include: Open Source Maps (incl. classic, cycle trnasprot, osmarender, openpiste), Google (classic, satellite, hybrid, terrain, korea), Ovi-Nokia maps, Yahoo, Bing, Open Source Maps-regional, My Topo . . . and a whole bunch of other, mostly European, map sources).

I've also tried gvSig Mini Maps . . . a potentially powerful gis software (when coupled with the desktop version), but it's waaaaaaaaaay harder to use, more limited in the sources from which users can download (although the on-line list is similar), and really difficult to convince my PE that the downloaded maps really are there.

Anyhow, enjoy
