Remote sensing techniques in the analysis of change detection

Abstract
A review of remote sensing techniques in change detection studies is presented. Due to the nature of imagery examined, most change detection studies have involved the use of Advanced Very High Resolution Radiometer (AVHRR), Landsat Thematic Mapper (TM) and Multispectral Scanner (MSS), SPOT data, and aerial photography. Change detection techniques have included transparency compositing, image differencing, classification, band ratioing, and principal components analysis. This paper will focus on a review of the utility of these methods for various resource applications.
