Generate an Elevation profile

1. Open a Project.
2. Select the 2D or 3D view. The 3D view is recommended in order to ensure the correct starting and ending points are picked.
3. 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.
4. Draw a (poly)line. Double-click to end it.
5. On the right, on the details panel, click Generate elevation profile.

The elevation is computed from the Elevation map for each pixel of the (poly)line. By default, the resolution is the ground sampling distance (GSD) of the project. 

Measure on an Elevation profile

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. 

Export an Elevation profile

In the Elevation Profile panel, click  to export the Elevation profile as a CSV file and save to desktop all its 3D points.

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.
