How to Plan and Fly Corridor/Linear Projects with the P4RTK
The instructions below will walk you through the steps needed to fly a mission in the GS RTK app. If you want to use a file to plan your mission, instructions on importing KMLs into the GS RTK app can be found here: Importing KML Missions.
Plan the linear flight mission in the GS RTK app
- Select Linear Flight Mission in the mission plan page.
2. Draw a line on the map by tapping points or import a KML as a data resource.
3. Using the linear element as reference, expand the buffer in both left and right directions based on the mission specifics. The expansion distance for each side is a minimum of 10m and a maximum of 2000m (2km).
4. If the linear element is longer than two kilometers, it will be cut into several sub-missions, with a minimum length of 0.5km and a maximum of 2km.
5. Set the flight height, speed, camera parameters, and overlap rate as you would for 2D mission planning.
6. There are two flight modes for linear missions: Full Coverage and Efficiency. Full Coverage mode has one or two turns more than Efficiency mode. We typically recommend Full Coverage to assure that the area of interest you're looking to survey has the correct overlap for modeling/corrections.
7. Name the mission, and tap OK to save.
Flying the Corridor
As with other PPK workflows, we require the use of at least one AeroPoint during the drone's flight. For best results, place one AeroPoint (or other ground control point) at each end of the linear corridor, and at 0.75mi intervals. If you only have one AeroPoint, place it near the location you're flying from.
Once you've laid your AeroPoint(s) out and turned them on, select Invoke on your mission or go to Flight page. The missions list is on the left side of the page.
If your mission is broken into segments, you'll see each one has a number associated with it. You can select a sub-mission by tapping that number, and verify that the mission is selected by seeing that it's highlighted compared with the others.
Note: It's important that each mission be at least 10 minutes of flight time to gather the required amount of GPS information for processing.
I still can't do it!
