on Remote ID compliance - what module are you using?
Heads up: if you're flying under a Part 107 waiver, Remote ID requirements may have additional conditions. Check your waiver language. Some legacy waivers need to be updated.
on M4E vs M3E - worth the upgrade?
Appreciate the real-world input. Sounds like I'll keep the M3E running until it dies or DJI releases something more significant. Maybe put the upgrade budget toward training or software instead.
on What overlap settings are you using for construction sites?
Don't forget speed. High overlap doesn't help if you're flying too fast and getting motion blur. At 250ft with 75/75 on an M3E, you should be around 25-30 mph max. Some people crank up the speed to finish faster and wonder why their results are mushy.
on Coordinate system headaches - NAD83 vs WGS84 vs local
The real answer is to push back on clients when they give you weird requirements. If they want State Plane, they should provide control in State Plane. Don't let coordinate gymnastics become your problem.
on Anyone tried the Autel Evo Max 4T for mapping work?
Tested one for about 3 weeks. The hardware is solid but the mission planning software is years behind DJI. No terrain following worth trusting. Had to use third-party apps for anything complex. Image quality is good though, and Pix4D processes the photos fine.
on RTK vs PPK - when do you use which?
Good summary Pete. I'll add: **Use RTK when:** - Good cell coverage or close to your base - You need to verify position quality during flight - Quick turnaround matters and you don't want post-processing **Use PPK when:** - Remote sites, poor cell coverage - Very long flights where connection might drop - Maximum reliability matters more than real-time feedback - You want to process with CORS data instead of your own base Many of us use RTK during flight then ALSO run PPK after as a backup. DroneDeploy calls this Auto-PPK. Best of both worlds.
on How many GCPs do I actually need with RTK?
Anna's right about checkpoints. The thing people miss is that RTK reduces how many GCPs you need, it doesn't eliminate the need to verify. For internal use or progress monitoring? RTK only is fine. For deliverables going to a client or engineer? Use checkpoints at minimum. For legal/boundary work? Full GCP network, period.
