Hello everyone. I have used the sentinel 2 toolbox for calculating vegetation indices with sentinel-2 dataset. However, for my project now, i have taken some images with a drone (both RGB and infrared images). Now i have a 5-band raster with the blue, green, red, red-edge (680 - 800) and NIR (800 - 900) spectral bands. These images are just have raw digital numbers (DNs) and no calibration panes were taken in the field for calibrating and converting DNs to reflectance values which are required for calculating vegetation indices.
I was wondering what information does the sentinel toolbox used to calculate vegetation indices. Are the spectral bands sufficient for calculation? i.e. i can just choose the input bands and results are reliable?
Thanks! any advice on this is very useful!
