effect of accuracy on GDS in sparse and dense cloud
« on: October 22, 2021, 06:13:09 PM »
Hi all, I need an information (very basic probably). I know that if I process my images in low accuracy I downscale of a factor of 1:8 (i.e., if my GSD=10 cm than I will have GSD= 80 cm) My question is: if I process images in low accuracy both in the sparse and dense cloud step do I apply this factor two times? example: my GSD is 10 cm, I calculate sparse cloud in low accuracy than I have a GSD of 80 cm. If I further process the dense cloud in low accuracy, my GSD will be then  640cm? or the factor still apply to the original resolution (i.e. my final GSD=160cm )?


Many Thanks
