We currently fly the DJI M600 Pro with the Zenmuse X5R 20 Mp camera. We generally fly between 200 and 300’ AGL to assure overlap and coverage and we get decent Surveying level Horizontal and Vertical accuracies (0.02’ - 0.4’ Horizontally and 0.20’ Vertically respectively). We Survey-in our GCP’s minimum four usually 6-8, and mark them on ALL photos they’re visible. Our GSD is usually right around 0.7 to 1 inch or so (+/-).
So I’ve seen a few Surveyors talking about using a 100 Mp camera, i.e. Hasselblad for example, and began wondering. If I upgrade, will this increase my H and V accuracies and precisions? Perhaps marking the GCP’s on images being a little easier??
