There are two main parts to successful data collection for drone mapping: Planning and Flight. For this Quick Start guide we will do a very minimal walkthrough to show the process from start to finish.
The walkthrough assumes that you already have the device connected to the remote and everything powered up. Open the DJI Go app just to make sure that everything is in working order. Close it before opening Map Pilot.
If you are are not connected to the aircraft, you can simulate the current location of the aircraft by double tapping on the map to draw a purple dot that denotes the anticipated takeoff location.
NOTE: All of these planning steps can be done without the need for a connection to the aircraft (red triangle). Double Tap on the map to designate where the takeoff will occur. This will draw a purple dot.
If you are connected to the aircraft make sure that it has a clear view of the sky. The red triangle and Flight Control panel will not show until there is a solid GPS fix and a valid flight plan.
- Identify the Survey Area. Make sure the terrain of the area is known and all tall features or structures are taken into consideration.
- Open the Flight Plan Stats pullout menu to see the metrics for the flight.
- Open the Altitude Adjustment pullout menu to check the current altitude flight will be planned for.
- Open the Map Control pullout menu to change the units.
- Place Boundary Markers by tapping and holding the locations where you would like define as the corners of your survey area.Boundary Markers can be single tapped to be removed or tapped and held again to be moved.A line is drawn between the first and second points since a valid flight plan has not yet been defined.As Boundary Markers are draw, the flight path with start to be formed.
- Use the Altitude Adjustment slider to adjust the altitude of the flight which determines the level of detail. Fine adjustments can be made by tapping on either side of the slider.
- Adjust Flight Path's primary pass direction using a two finger rotate gesture. Try to minimize partial passes while making sure the flight path is safe (including the flight path from the Home Point to the starting point and from the ending point to the Home Point).
- Open of the Map Control pullout menu to save the mission.
- Press the Save button on the left to save the mission for offline use or to repeat it.
- Open the Flight Control pullout menu and push the Upload button. This will execute a pre-flight check to makes sure the system is ready to collect data.
- The mission will be automatically uploaded to the aircraft.
- Verify the programmed flight is correct by checking the light blue line. If everything looks OK, press the Start button to begin the flight. Be sure to check the first and last legs of the flight to verify that the home point was set properly.
- The aircraft will automatically ascend vertically to the cruising altitude and set the gimbal to nadir (straight down).
- The aircraft will automatically proceed to the beginning of the flight path.
- The aircraft will automatically navigate along the flight path taking images at appropriate intervals.
- Once the mission is complete, the aircraft will automatically proceed to the point above the Home Point.
- The aircraft will automatically descend and land at the Home Point.
- Mission is complete.
