Will DroneDeploy support the new DJI M30?
My guess is no.
From DJI’s FAQ:
Does the M30 series support accurate mapping?
Not supported. TheM30 series is not designed for aerial surveying. Users can plan a flight path and capture photos in the aerial FPV mode of DJI Pilot 2.0 App, but the model’s accuracy is not guaranteed.
You can use DJI Pilot 2 to get a flight route, then upload the photos to DD. I have mapped using Mavic 2 and M30 and uploaded both, the maps look identical.
