My project is to make my Galaxy Tab a GPS mapping machine for plotting new enduro trail live in the woods, on an aerial photo overlay, with no WiFi or cell connection. I downloaded Path Away, but was unable to get the aerial overlay, could very well have been operator error! Got the Trimble Outdoor Navigator and had an overlay before I knew it! It caches the map tiles for use offline. I have downloaded aerial hybrid tiles for the general area around Wilkesboro NC, where I will be riding a DS this weekend, and plan to do some preliminary testing. Dont know about y'all, but my eyes are too old to be looking at matchbook sized display screens!
