- Open an inspection project and select the 2D or 3D view. The 3d view is recommended in order to ensure to pick the correct starting and ending point.
- Add a distance measurement: click or add an item to the annotation layer by clicking when hovering it and select Measure a distance or elevation.
- Draw a (poly)line. Double-click to end it.
- At the right on the distance details panel, click Generate elevation profile.
The elevation is computed from the DSM for each pixel of the (poly)line. By default, the resolution is the ground sampling distance (GSD) of the project.
On the bottom panel, move the mouse along the curve to display the elevation and its location on the profile. Zoom in for more precision. The zoom level on the curve can be reset by clicking on Reset Zoom in the Elevation Profile panel.
The horizontal axis represents the length of the (poly)line whose origin (0 value) corresponds to the first clicked point.
The vertical axis corresponds to the elevation of the model.
In the Elevation Profile panel, click to export the elevation profile as a CSV file and save to desktop all the 3D points of the elevation profile.
The following columns are exported.
- X, Y: horizontal coordinates in the output coordinate system.
- Z: vertical coordinate in the vertical output coordinate system, in metric or imperial units depending on the account preferences.
- Distance: ground distance from the origin of the profile in meters or feet depending on the account preferences.
