CONCEPT The underlying concept of the Change Vector Analysis procedure is simple. Given multi-date pairs of spectral measurements, one computes spectral change vectors and compares their magnitudes to a specified threshold criterion. The decision that a change has occurred is made if that thres hold is exceeded.

WebThere are many different change detection methods (see Jensen’s textbook). We will use the spectral change vector analysis method (CVA - see p.484) to process the 80s and 90s NALC data. Most change detection methods are sensitive to spectral differences between images that are not necessarily a result of land-cover change.
