1. Description

Contour Lines are defined as lines joining all points of the same elevation on a map. Aether calculates and displays these lines using a Digital Surface Model (DSM). These lines can notably be used to assess how the terrain is profiled.

2. Generating Contour Lines

Contour lines can be obtained once a Photogrammetry process‍ has been completed with an orthomap and a DSM available as layers, or after having imported these inputs processed from third-party software.

Step 1 - Open a Project and select a Survey.

Step 2 - Press the Analytics button from the left panel and select the Contour Line analytics.

Step 3 - Select the Elevation Model you wish to use as an input to generate the contour line.

Step 4 - Enter the following parameters:

• Output format : dxf, shapefile or json
• The other parameters are descibed here

Step 5 - Click on "LAUNCH LOCAL CRS CONTOUR LINE EXTRACTION FROM DSM".
