Webchange vector. A. 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.
