The topographic map was specially designed to allow you to quickly navigate off-road.
It includes altitude lines with text labels with the different altitudes.
All dirt-roads are graded by ground condition using up to 4 different levels with easy identifiable colours.
The offline map source includes OSM data and SRTM1/Lidar contour lines that can go as low as 10m.
