I am trying to get a NDVI image from an RGB + NIR image captured by a modified Cannon S110 camera bought from Event38 along with a 3DR Iris+ drone link
I have previously experimented with python and rasterio and successfully calculated an NDVI image from 2 images (one RGB and one NIR).
Researching around the internet I have found this to be achievable from one image. However I haven't found any image manipulation library to be helpful.
Can someone with more experience in this offer any guidance? Any programming language is welcome.
