7.9 Area & DTM Volume
7.9.1 Overview
Description Area & DTM Volume is a program used to compute online areas to a maximum of 50
points connected by straights. The target points have to be measured, selected from
memory, or entered via the keypad in a clockwise direction. The calculated area is
projected onto the horizontal plane (2D) or projected onto the sloped reference plane
defined by three points (3D). Furthermore a volume can be computed by automatically
creating a digital terrain model (DTM). Area division is also possible for 2D areas.
Access
Map contents The graphic on the Polar page shows the area projected onto the reference plane. The
points used for defining the reference plane are indicated by:
• for measured points.
• for manually entered points.
• for stations.
• for points defining the reference plane.
The graphic on the Plot page shows additionally the area projected onto the reference
plane, the horizontal distance between the points the perimeter and the area.
