Hi all,
I’m finding some troubles with the values of various indexes that come out of drone mapping. For the image collection I’m using a Mavic 3M.
At the moment I’m using NDVI and NDRE but I get values with really low difference between max and min. For example 0.1 or 0.2. In addition NDVI saturates quite early in the season.
So I was wondering, is there any way, during the image collection or during the image processing, to increase the difference between max and min of the indexes and avoid that NDVI saturates early?
Thank you very much for the help.
Hi Filippo,
Using a reflectance target could help in these cases. May I ask if you are already using one?

Hi Jose,
No I don’t use one. I tought that the sun sensor on the drone was enough.
Thanks a lot for your help
