What are people using to plan and process drone surveying? My workflow is a bit convoluted, and I'd like to find out how others plan, execute, and compile their datasets.

Here's how mine works:

• create a quick kmz in Google Earth
• import that to DJI Flightplanner software (I paid $100US a couple of years ago for a permanent license, I hate subscription based fees)
• plan the actual flight path using Flightplanner; it's a bit finnicky, but I've got it pretty much dialed now
• export that path to csv for use with Litchi
• park myself as close to the grid or centre of it as I can to minimize time wastage
• use the Litchi software on my device to execute the flight path(s)
• bring the dataset back into my desktop
• process using WebODM

Note this is from memory; I haven't actually flown a survey since 2023!

I have found that with my relatively fast and RAM-rich computer (32GB, was top of the line 2.5y ago), I can create photogrammetric 3d surfaces and very good orthophotos for up to ~600 drone photos this way. Beyond that, my computer can't hold enough of the images in memory for analysis (there may be other ways to compensate for this, I'd say I'm an intermediate amateur WebODM user, but I haven't been able to thread that needle). There is a possibility through WebODM to access "Lightning" a super-computer processing network for larger datasets, but it is a paid service and requires an account that I've never bothered to create.
