Terrain Follow
When collecting data in areas with large elevation differences, such as mountainous areas,
Terrain Follow allows the aircraft to adjust the flight altitude following the changes in the
terrain. Terrain Follow ensures that the relative height of the aircraft and the ground below
remains unchanged so that the Ground Sampling Distance (GSD) of the photos collected in
each area is consistent, improving the accuracy of mapping data while ensuring flight safety.
Real-Time Follow
Real-Time Follow does not require DSM files. The aircraft vision system detects the terrain
fluctuations 200 m ahead in real time during the flight. It is recommended to use this
function in areas where the terrain slope is less than 75° and the lighting condition and
environment are suitable for the vision system.
