Hi,
I only use ENVI pretty rarely, and was wondering if you could help me with this one:
I've a RGB image and a NIR image of the same valley, and need to extract the "red" pixel values from the RGB and the NIR values from the NIR image.
Firstly, is there anyway I can make a composite, so I can calculate NDVI directly via Band Math?
If not, how do I extract the R pixel values from the RGB and the NIR values from the NIR image?
Any ideas/help/solutions would be highly appreciated.
Best regards,
Jannik - a bit of a ENVI novice...
