STATISTICAL COMPARISON OF SPOT SPECTRAL MAPS WITH FIELD SOIL MAPS

The field soil map is not the only appropriate standard for evaluating spectral maps. This study was undertaken to evaluate both the field soil map and the spectral map independently, according to the degree to which they minimize within, and maximize among, unit variability of pertinent soil properties. Units on the field soil map are defined in terms of soil properties that affect use and management, whereas units on the SPOT spectral maps are based directly on spectral properties only. Characterization of SPOT mapping in terms of significant soil properties would be a necessary next step after generation of spectral maps. -from Authors
