If you’re looking for off-road navigation then you probably have a dedicated GPS device that you use instead of a smartphone. Even with off-network capability, these apps aren’t incredibly helpful most of the time when you’re backpacking in the middle of nowhere, or trying to find your way through a rural area. And, while I’ll never try and sell you that smartphones are better than GPS (they aren’t) if you have an iPhone, this new app might be something worth looking into.
Maps 3D Pro costs about $5 on iTunes, and is actually designed for hikers, cyclists, skiers and outdoor enthusiasts. Not only does it give you terrain and altitude details and download to your phone, but you can actually select what kind of map you want based on where you’re going. Maps 3D Pro draws maps from NASA satellite views, 3D topographic maps, Open Street Maps (for city navigation) and USGS maps just to name a few. You can look at the maps in regular 2D or in beautifully rendered 3D, depending on your needs. You can even zoom and rotate around the 3D version–sort of like a Google Earth for your phone. If nothing else, it’s kind of pretty to play with. read more
