Who can use this feature

Editors of a project within a Professional or Pro + workspace.

The terrain profile tool on GeoNadir allows you to visualize and analyze elevation changes across a landscape. It creates a cross-sectional view of your terrain and also shows the differences between your DSM and DTM. You can use this difference to estimate vegetation and building heights.

  1. Select a dataset

  2. Select a line

  3. Click the terrain profile tool from the top menu bar (or use the keyboard shortcut 'Shift + T')

Note that the elevation values as shown on the y-axis of the terrain profile will not be correct unless you have uploaded GCPs with your data. While the horizontal positional accuracy of drone data is usually within a couple of meters of reality, the vertical positioning can be several meters off.
