I’ve used this for years to navigate the mountains and canyons of the Western US. It is the most reliable, complete OFFLINE map I’ve found. It’s imaging and shading are very useful for getting a sense of the terrain, vegetation, and even where sunlight is hitting.
The limitations are that the dirt road and trail accuracy is decent, but not great. Eg here in Idaho there are old roads that traverse private property or are defunct, still shown here. However, this isn’t alone in that problem, most other maps have the same issue.
The good news is that this also includes some roads and trails that the other major maps are missing.
The user interface is a bit unusual at first, but once used to it, it is powerful.
I always keep a copy of this on my devices, you never know when the zombie apocalypse will knock out the internet (or maybe you just go out of cell range).
