MISSION SETTINGS button opens dialog where you define mission parameters.
Mission parameters are applied to newly added waypoints.
In order to update settings of the waypoints drawn on the map please use below described methods:
oWaypoints added with WAY PTS drawing mode can be updated through the respective waypoint dialog.
oWaypoints added with AREA PTS and STREET PTS drawing modes can be updated as group. You should first select area/street area and then open Mission Settings dialog to change settings for the selected area.
Parameters
Mission settings define behavior of UAV during the flight (like UAV speed and altitude) as well as photographs quality and camera triggering interval. When drawing a flight plan waypoint altitude and speed values are calculated according to these settings.

WARNING: Terrain elevation should be checked on topographic maps. In some cases DEM does not have correct values or any values (when flying outside of the covered area) which can lead to an unsafe situation. If this is the case you should adjust altitudes of waypoints in Mission Settings/Waypoints dialogs according to the information from topographic map.
Parameter |
Definition |
Value |
|---|---|---|
Height |
UAV's height above ground level (AGL) in each waypoint. |
Min: Equals Minimum Height Above Ground setting. Max: 3000 m |
Speed |
UAV's speed in each waypoint. |
Min: Value depends on the selected airframe. Max: 22 m/s |
Overlap |
Photographs overlap percentage. NOTE: If overlap factor of selected area is changed during the flight a new overlap will be applied automatically. ppX UAS: Select Show Photos and Check Photos to visualize the photo coverage during the flight. |
Min: 0% Max: 90% |
Sidelap |
Sidelap percentage. Select Show Photos and Check Photos to visualize the photo coverage during the flight. NOTE: Changing of sidelap factor of selected area changes number of flight lines. To apply the change upload of the waypoints is needed. |
Min: 0% Max: 90% |
GSD |
The quality of a digital image depends on number of pixels used to create the image. The Ground Sampling Distance (GSD) is the distance between two consecutive pixel centers measured on the ground. The bigger the value of the image GSD, the lower the spatial resolution of the image and the less visible details. EXAMPLE: GSD of 5 cm means that one pixel in the image represents linearly 5 cm on the ground (5*5 = 25 square centimeters). |
GSD value range depends on selected camera and lens. Flight altitude and GSD are exclusive choices. The higher the altitude of the flight, the bigger the GSD value. |
Overshoot |
Overshoot factor is used to set the distance of overshoot from the marked area (outside of the blue area line). Overshoot factor should provide the UAV with enough time to turn around a waypoint and position above destination flight line when entering area or street area.  Overshoot example. |
Min: 100 m Max: 1000 m |
Camera (ppX UAS) |
Select the camera installed in your UAV. Just click on the displayed camera name under Selected Camera field to browse through the possible options. Press on right side of the button to increase move up on the camera list and press on left side to move down on the list.

Waypoint altitude can be relative to the ground or absolute to Home position. RELATIVE ALTITUDE MODE Selecting this waypoint altitude type makes the altitude relative to the ground. When calculating the altitude of each flight line in the grid, the higher Mean Sea Level (MSL) altitude of the two waypoints is used. In this way we insure that the UAV flies in straight line above the terrain (beginning and ending waypoints of a flight line will have the same MSL value), climbing/descending only when changing direction (turning). This is important in order to have photographs with the constant resolution. You can check your flight plan in 3D View (Google Earth) for the best understanding of relative altitude mode. EXAMPLE: In Mission Settings dialog set AGL value to 200 m. Select relative altitude mode. This means that the altitude of the position where the orange flight line intersects the blue area line will be 200 m above ground level or more. Draw area points. Now check waypoints' AGL and MSL values in Flight plan table. Notice that the two consecutive waypoints always have the same MSL (MSL of the higher waypoint). ABSOLUTE ALTITUDE MODE Absolute waypoint altitude type will make the altitude absolute with regards to Home Mean Sea Level (MSL) altitude. EXAMPLE: In Mission Settings dialog set AGL altitude to 200 m. Select absolute altitude mode. The UAV will fly 200 m above Home MSL altitude. If Home MSL is 100 m then the waypoints will have MSL altitude of 300 m (check waypoints' values in Flight plan table). |
