Terrain Settings

Quickly adding the contour interval to any map is the basic idea of FarigMaps.
In the main screen, make the Contour lines button on, you can get a contour line map in 1s. If you wish to clear the contour lines layer over the map, make the Contour lines button off.

Otherwise, you can set the terrain rendering, contour interval, elevation range in 'MUEN' - 'Terrain settings'.
