2) Set Ortho GSD, which specifies the GSD used by the RGB camera to collect images.
3) Point Cloud Density specifies the average number of LiDAR points (non-ground points) per
square meter in principle.

4) Set ASL/ALT to Relative to Takeoff Point (ALT), ASL (EGM96), or AGL. We recommend that
you select AGL to enable Terrain Follow.

5) Select DSM files. Matrice 350 RTK supports two methods of obtaining terrain data: Import
Local File and Download from Internet. In this example, select Download from Internet. The
app downloads terrain elevation data of the mapping area and generates a route with altitude
changes to ensure accurate terrain follow with the aircraft flying at obtained heights with strict
accuracy.

6) We recommend that you set Terrain Follow Altitude to 150 m. You can also set a lower altitude,
such as 100 m, if you need stronger laser penetrability to obtain more ground point information.
If the mapping area is sparsely vegetated, you can set a higher altitude, such as 200 m, to
improve operating efficiency.
