The method applies the iteratively re-weighted multivariate alteration detection (IR-MAD) algorithm to signal significant changes, recording the results in a highly compressed, georeferenced binary image. A prototype change extraction and archival system, implemented as an extension to the {ENVI}/{IDL} remote sensing data processing user interface, is illustrated using time series of {LANDSAT} {TM} and {ASTER} multispectral imagery over the Nevada Nuclear Test Site in the {USA}." }
