I am interested in mapping vegetation stress utilizing the blue shift to the red edge phenomenon in remote sensing. The figure below shows the expected change in reflectance of green leaves under stress. I would ideally like to produce a raster-based change map utilizing commonly available multispectral imagery (e.g. 4-band NAIP, Landsat, etc). Are there any well developed methods to put this phenomenon into practice within a GIS or digital image processing software? Any step-wise advice to accomplish this would be of great help.
