Is the DJI PHANTOM 2 VISION + camera accurate enough for professional topography? - NO GCP's

Is the DJI PHANTOM 2 VISION + (phantomvisionfc200_5.0_4608x3456 (RGB)) horz & vert accuracy ok in 5m & 10m sufficient for accurate professional topography?

I have enough (140) overlapping photos and up to 6 Manual Tie Points matched in 10+ photos avg.


I already watched the webinar about GCP’s and answered this question thankyou.

Hi Ben,
With the Phantom 2 Vision+ you can already achieve a very good relative accuracy. The GSD that you typically obtain flying at 50 meters is between 1.7 to 2.7 cm/px.

However, if you are interested in absolute accuracy especially for the accurate professional topography we would definitely recommend to use GCPs. Especially knowing that the calibration of the altimeter of the Phantom 2 Vision+ is more or less 10 meters. This means that without GCPs your model could be shifted more or less 10 meters from its real position.
