Area scan


Area scan is similar to a Photogrammetry tool, except for Area scan there is no need to set the Ground resolution (GSD) and camera settings. This is a simpler way to plan flights over an area. Parameters to specify height, side distance, and perimeter.
Additionally to all common options, these features are available for the Area scan tool:

Move / Rotate segment select + hold the blue circle in the center to drag and drop the Area scan segment to another location. Select + hold the circle’s rim to rotate the whole segment.

Flight height altitude of flight along the area.

Altitude type AMSL or AGL to set Flight height.

Side distancesize in meters between lengthwise route lanes.

Direction angle is used to change the direction of the main scanning progress. By default, the algorithm calculates a route scan in a bounded polygon so that the main course of the scan is performed in the direction of "South-North".

Overshoot (m) adds an extra segment to both ends of each survey line to enable extra space for turns.

Overshoot speed (m/s) option to decrease/increase vehicle speed for overshoot segment while passing turns.

Allow partial calculationoption to allow route calculation in these cases:
a. The part of the route exceeds the maximum AMSL of route
b. Relief height is unavailable at some point(s) of route
c. The part of the route exceeds the maximum fence radius
d. The part of the route in the No-fly zone (NFZ)
Calculation error may appear if trajectory fixed height is lower than safe height over terrain at some route point.

AGL Tolerance (m) – allows flying straight trajectories over the slightly waved landscape, by specifying how precisely the UAV should follow the required altitude above ground. To maintain specified height additional waypoints will be added if the difference in height is larger than AGL tolerance. The smaller the AGL tolerance value, the more amount of waypoints will be generated. If AGL tolerance is set to 0 (zero) UAV’s altitude will be constant throughout the route, but many additional waypoints will be added.

No action at the last point removes action for the last waypoint.

The double grid if enabled, adds a second grid to the survey are in a 90-degree angle according to the first grid.
