I have a problem with NDVI Calculating. I use LibTiff.Net and I'd like calculate NDVI from two Tiff images.
I read many documents (for example: http://en.wikipedia.org/wiki/Normalized_Difference_Vegetation_Index ).
I need spectral reflectance measurement property for NDVI. Unfortunately I can't get these property from Tiff Tag's.. Which is the spectral reflectance measurement Tag?
How can I calculate NDVI with BitMiracle Libtiff?
