Volume Calculations

The volume calculations give accurate results for the volume of an area. The area of cutting and filling is found out for each section with the Polygon method or Net area calculation method. The volume is determined by multiplying the average area with the distance between sections.

1. Like measuring the elevation profile and spot elevation, select the polygon tool from the toolbox and draw an area anywhere on the map to calculate the volume.

2. Click on the area and select 'Elevation Profile' from the toolbox. Select the method parameter as 'Base Height' and layer as 'DSM' in the dialog box.

3. Click on 'Calculate Volume'.
