17.6 Record and calculate volume
Positions of a terrain are determined in order to record volumes. When recording, choose positions that
represent the terrain well.
When calculating in the field, the volume can be determined in relation to a reference height (input) or in
relation to a (measured) reference surface. In addition, a polyline (area) enclosing the terrain is always
required for the calculation.
The terrain within the ring can consist of single points, breaklines or areas.
