I'm using AgiSoft photoscan to create a photo mosaic from aerial images. The images are being captured using a camera modified for NIR and RGB data capture.
I want to be able to perform spectral mixture analysis on the image using a package like ENVI but am unsure where to start or if this is even possible.
I assume that I would need to first create a mutli band raster from the single exported ortho GeoTIFF from Agisoft Photoscan. But even this I'm not sure about. Can anyone point me in the right direction please?
