17.1 INTRODUCTION
17.1.1
Map Comparison
Map comparisons are fundamental in remote sensing and geospatial data analysis for a wide
range of applications, including accuracy assessment, change detection, and simulation modeling.
Common applications include the comparison of a reference map to one derived from a satellite
image or a map of a real landscape to simulation model outputs. In either case, the map that is
