How to perform volume calculations?

Volume calculations provide accurate measurements for the space in a given area. The cutting and filling area for each section is found using the polygon or net area calculation method, and the volume is determined by multiplying the average area by the distance between sections.

1. To begin calculating an area's volume, select the polygon tool from the toolbox and draw the area on the map.

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 dialogue box.

3. Click on 'Calculate Volume' and view the result.

How to perform elevation calculations?

Measuring Elevation Profile

An elevation profile is the description of a two-dimensional, cross-sectional landscape view. It provides a side view of a terrain elevation along a line drawn between locations on the map.

2. Click on the line drawn and select 'Elevation Profile' from the toolbox.

3. In the elevation profile dialogue box, set the parameters. Choose the method as 'Line' and the interval as '1m' or lower. Set the layer as 'DSM' and click on 'Calculate Elevation'.

Measuring Spot Elevation

Spot elevation, or a point on a map or chart, indicates points higher than their surroundings. Spot elevation displays the actual elevation of a selected point and the top and/or bottom elevation of elements with a thickness.

1. To check spot elevation, select the marker tool from the toolbox and place it on the desired point on the map. Then select 'Elevation Profile' from the toolbox.

2. In the Elevation Profile dialogue box, select the method parameter as 'Point' and layer as 'DSM'.

3. Click 'Calculate Elevation' to get the spot elevation results.
