Where is North – Compass needed

For displaying a compass overlay on the map you have to enable the displaying of UI Elements from the settings menu:

Toogle GUI elementsx

To “normalize” the map (that is: heading north on top of the map) simply invoke the “Heading North” command from the secondary menu like shown below

Normalize Map in EarthView

and the current map will rotate in order to have heading north on top of the map.
