Preparing Files
The DSM les of the measurement area can be obtained through the following two methods:
A. Collect the 2D data of the mapping area and perform a 2D reconstruction through DJI Terra by
selecting Fruit Tree mode. A .tif le will be generated and can be imported to the microSD card of
the remote controller.
B. Download the terrain mapping data from a geobrowser and import to the microSD card of the
remote controller.
Make sure that the DSM file is a geographic coordinate system file, and not a projected
coordinate system le. Otherwise, the imported le may not be recognized. It is recommended
that the resolution of the imported le should be no more than 10 meters.
