<p>I think the accuracy cannot explained in few words. There are too many factors influencing it like type of drone, type of camera (resolution, lens), height of flight, terrain to name a few.</p> <p>Depending on some of these factors one can determine the area one pixel on the camera chip represents. The accuracy can get as good as to 2-times the area horizontally and 3-times vertically.</p> <p>That was a very shortend excerpt from this website: <a href="http://geoawesomeness.com/accurate-drone-survey-everything-need-know/">http://geoawesomeness.com/accurate-drone-survey-everything-need-know/</a></p> <p>Regards, Volker</p>
