Hello, I'm about to start working with Photoscan, NIR aerial images and a UAV to calculate NDVI for Agricultre. But I have so many doubts.
When I generate a Orthophoto with NIR Images, instead of a RGB I'm getting a NIRGB, where NIR replaces Red.
But the formula for calculating NDVI is NIR-R/NIR+R. So how do I get NIR and R in separate bands to make the calculation?
I've noticed that Photoscan generates a 4 band Orthophoto, is the NIR placed in Band 4? Or it's left empty. I have noticed on regular RGB mosaics that the band 4 is empty, so I thought maybe Photoscan extracts the NIR and place it on Band 4. That would solve my problem.
Thanks in advance, looking forward for an answer.
