User Manual
For Oblique missions, “Forward Overlap Ratio” refers to the overlap ratio for the nadir view ight
path, and “Forward Overlap Ratio (Oblique)” refers to the overlap ratio for the oblique flight
paths.
3. Course Angle
The angle of the main path. North is 0°, with a positive value when it is clockwise. The range can
be set from 1° to 360°.
4. Margin
Expand (positive value) or narrow (negative value) the area margin for control over the area of
ight. The range can be set from -30 to +30m.
5. Mission Relative Height
The relative height between the takeoff point and the area being mapped.
NOTE: Make sure to set the correct relative height. Otherwise, the overlap ratios will be affected
which may have a negative effect on the mapping results.
Users can adjust the overlap ratios, altitude, and gimbal pitch angle (for Oblique mission
only) according to actual situations. Reduce overlap ratio accordingly for areas with less
terrain uctuations. Increase overlap ratio accordingly for areas with more terrain uctuations.
However, it is recommended to set a side overlap ratio of no less than 60% and a forward
overlap ratio of no less than 65%. For objects that require highly detailed results, create
multiple missions to cover more perspectives of the desired area or object.
