What are the differences between Gaia GPS and CalTopo? I am looking for a GPS backup. On my last excursion my Garmin was getting numerous satellite locks but refused to triangulate until I updated the software once home. Fortunately I use map and compass and typically confirm my location at the end of the day with the GPS.
I would also like to print my own maps from the perspective of being a canoeist who paddles in the Alaskan Arctic. I prefer maps at a scale of 1:50,000 with UTM coordinates and topo lines printed on 8.5×11 waterproof paper. Being able to layer all man made objects (homesteads, bridges, winter roads, etc.), vegetation changes, historical/archeological points of interest and water hazards is a plus.
I’m an Apple user if that makes any difference.
