Dear support,
I am using the multiSPEC 4c and I have one problematic dataset where the red reflectance map gives very strange values, resp. I can’t compute the NDVI. I am attaching a printscreent.
Thank you for your help!
Hi,
The values of the reflectance map will lie between 0-1 only when a radiometric target is used. Are you using a target? If yes, it also might be that the target is overexposed/underexposed and the values were not used for radiometric calibration.
