Guys, I’m testing the Mavic 3M and I got an average GSD of 0.79 cm…  According to the RMS processing error, when measuring the height of a  plant, can I say that I would be making an error of approximately 0.5  cm? Or in another way, I must use the rule of 2 to 3 times the GSD of 0.79  cm, that is, the error in measuring the height of the plant would be  2.37 cm and not 0.5 cm. Which is right?
Anyone can help me ?
