Drone mapping outputs

Before a job starts, you pick what it should produce. Six outputs are available, each shown as a card with a preview and its download format.

The six outputs

• Orthomosaic map GeoTIFF A georeferenced aerial map. Marked Recommended, and the one to pick if you are unsure.
• Digital Surface Model (DSM) GeoTIFF Surface height, including buildings and vegetation.
• Digital Terrain Model (DTM) GeoTIFF Bare ground height, with objects filtered out.
• 3D point cloud LAZ The site as millions of coloured 3D points.
• NDVI vegetation map GeoTIFF A vegetation health index map. Needs multispectral imagery and a Pro plan.
• Thermal map GeoTIFF A surface temperature map. Needs radiometric imagery and a Pro plan.

Cards you cannot select

If the quality check does not find a matching sensor in your images, the NDVI and thermal cards stay disabled and are labelled Camera not recognised. This is not a setting you can override: the data simply is not in the files. See image requirements.

Choosing

• Working with heights? DSM and DTM are separate outputs, so select both if you want to compare them.
• Need volumes? Volume measurement in the viewer is computed from the DSM, so select it.
• Mixed sets are fine. RGB and multispectral or thermal images can go into one project, and each sensor is processed into its own layer.
• More outputs means a longer job, since each is generated from the same reconstruction.

Tip

Select everything you might need in one go. A project can only be reprocessed once, and only while the raw images are still stored.

You also set a quality level, which controls the resolution of the result.

If the project has ground control points, choose under Position with whether this run uses the GCPs, the drone GPS, or both.

After processing, open the Outputs tab in the viewer to download results in the original or another coordinate system.
