Elevation profile and cross-section on the cloud

How to create an elevation profile

 
Information: The elevation profile is only available under one of these conditions (alternative):
  • The project has been processed on the cloud and is georeferenced.
  • A DSM result was uploaded to the cloud and is georeferenced (GeoTIFF).
To create or visualize the profile in the 3D MODEL view, the point cloud or mesh should be generated or uploaded besides one of the conditions above. Note that the elevation profile is not transferred from one view to the other.


1. Go to Pix4D Cloud and log in with a valid Pix4D account.
2. Select a project.
3. On the left sidebar, select the view MAP or 3D MODEL.
4. On the right side of the view, click ic_line_black.png.
5. Draw a (poly)line. Double-click to end it.
6. On the right panel, click GENERATE ELEVATION PROFILE.

How to 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 horizontal axis corresponds to the length of the (poly)line, the origin (0 m) corresponding to the first clicked point. The vertical axis corresponds to the elevation of the model. For more information about the coordinate system: 360000252583 (see Default coordinates > Vertical). The elevation is computed from the DSM for each pixels of the (poly)line. By default, the resolution is the ground sampling distance (GSD) of the project.

There are two elevation profile features:

ic_export_black.png Export as CSV and save to desktop all the 3D points of the elevation profile.

 
Tip: The following columns are exported.
    • Horizontal coordinates (X, Y): Output coordinate system of the project or the one detected in the GeoTIFF DSM.
    • Vertical coordinate (Z): Output coordinate system of the project or the one detected in the GeoTIFF DSM in meters or feet depending on the account preferences.
    • Distance: Ground distance from the origin of the profile in meters or feet depending on the account preferences.
