Found this recently: Online Flight Planner: Aerial Imaging, Mapping & Survey – SkyIMD – Aerial Imaging, Mapping & Data
For my Mini 2, I’d been looking for something that would easily create grid waypoint missions for Litchi, but allow you control of various photogrammetry parameters (like Drone Deploy), but so far I’ve had to do calculations and create the grids manually.
This online tool ticks all my boxes.
Workflow:
In Litchi mission hub:
Define the area you want to map using waypoints around the perimeter.
Download the waypoints as kml
In skyIMD planner:
Upload the kml file to the skyIMD planner page
Adjust the photogrammetry options how you want (e.g. Mini 2 cameras (physical) focal length is 4.5mm, and it has the same sensor size as a Mavic Air)
If you want to use the ‘interval’ option in Litchi, just download the flight paths as kml
If you want to have a waypoint at each point a photo is to be taken, download the ‘paths with trigger points’ as kml
In Litchi mission hub:
Upload the kml file generated by skyIMD planner as a new mission.
Adjust the collective flight parameters for the waypoints to match those in skyIMD (e.g. altitude, interval or photo action, cruising speed, heading mode (Auto TNW), path mode (straight lines), gimbal pitch (disabled)
