How to calculate multiple volumes

You can calculate volumes for multiple zones at once. The polygon or polygons represent the outline of the area to be measured. Volumes can be calculated within one or more polygonal boundaries. A boundary polygon helps to determine the exact volume for a specific zone of the terrain model.

STEPS

Draw the necessary polygons around the areas for which you want to calculate the volume.
In the Comment field (Edit object: Polygon), you can enter a name or identifier that will be displayed in the report.
Select the boundary polygons (Shift + select) for which you want to calculate the volume.
Go to DTM > Volumes... to open the Volume Calculation window.

Under Method, choose what you want to calculate:

Multiple volumes with profiles: Volume calculation based on cross-sections.

Multiple volumes with prisms: Volume calculation based on triangular prisms.

Total volume with prisms: Volume calculation for the total of the selected polygons.

Click the Calculate button.

RESULT

After the calculation, the Volume Calculation Report window opens.
In the Tabular tab, you get an overview of the different boundaries (polygons) with the calculated data.

The text settings of the Volume Calculation Report can be edited as usual and exported to the drawing or an external file.

You can also directly calculate the total volume of both areas by choosing 'Total volume using prisms':
