Using Spectral Angle Mapper Technique (SAM) on Hyperspectral Images to Determine the Area and Location of Some Objects

This research depends on the relationship between the spectral reflectance and the nature of target in order to track it and draw boundaries and area of its spread, and even the proportion of its presence with other objects in the area to be measured. The greater the number of spectral channels used the greater the amount of extracted information from the studied target. The use of hyperspectral images requires complex processing techniques which differ in the means and methodology from those using multispectral images.
