  • Page 2: Information

    This document supports high resolution printing. Information There are two kinds of altitudes displayed in the DJI GS RTK app, absolute altitude and relative altitude. Absolute altitude: The geographical attribute, in relation to longitude and latitude. Relative altitude: The altitude data of the operation tasks relative to the Home Point. In the same operation, the absolute altitude for the same point during the operation will vary when taking off from locations with dif- ferent elevations.
