AbstractWeed infestation in commercial crops in Canada is a major problem to producers. To help the reduction of the amount of herbicides used for the control of weeds, the potential of high spatial resolution airborne hyperspectral data was exploited for the detection of weeds in a crop of canola. Both manual and automatic endmember selection approaches were used to extract the weed endmember spectrum from the image cube. Results obtained from constrained linear spectral unmixing using this endmember are discussed.
