SOIL PROPERTY RELATIONSHIPS WITH SPOT SATELLITE DIGITAL DATA IN EAST CENTRAL ILLINOIS

The second-generation remote sensing satellites with improved spatial and spectral resolution offer additional possibilities for conducting soil surveys. This study was undertaken to determine the relationships that exist among high-resolution satellite digital data and soil properties useful in map-unit delineation and classification. A second objective was to develop models (linear equations) based on soil properties to predict satellite spectral response. The results showed that most surface soil properties and some subsurface properties pertinent to soil classification and map-unit separation can be used to predict satellite data and vice versa. -from Authors
