    • Reference elevation: allows to define a reference elevation. Click Details to measure a GNSS point and assign to it a reference elevation. The elevations will be calculated referred to a plane passing by this point.

    • Geoid: allows to calculate the elevation over the sea level using a geoid. In order to get geoids from your country you must download the corresponding country package.
