The Map View contains:

 

Items

The Map View displays the following items:

 Displays the device's GPS position.

Shows the home point, i.e. the point at which the drone takes off. When doing a grid mission the drone lands automatically at the home point when the mission is finished.

Shows the position and orientation of the drone. The green arms are in the back of the drone and the red arms in the front. The green line shows the path the drone has flown.

Shows the locations where the pictures were recorded.

 Displays the grid size and estimated flight time for the Grid Mission.

 Shows the last waypoint of the mission. When the drone reaches this point, it comes back to the home point and lands for the Grid Mission.

 

Buttons

The Map View contains the following buttons:

Centers the map on the device's GPS position.

Displays a map background.

Displays a satellite background.

For a Grid Mission the following buttons are displayed:

 Moves the grid to the center of the screen.

 Starts the grid mission. It will guide the user through security checks before the drone takes off.

 During a mission, aborts the Grid Mission and the drone comes back to the home point for landing. The images that have already been taken are synchronized with the device.

For a Free Flight Mission the following buttons are displayed:

 Starts a free flight mission. It will guide the user through security checks before the drone can take off.

 During the mission, pauses the image acquisition.

 During a mission, resumes the image acquisition.

 During a mission, stops the image acquisition. The .p4d project file is created and the images are synchronized with the device.
