Soil resource data base generation using soil landscape models

The application of geographic information system technology to resource management enables simultaneous evaluation of several types of geographic data using overlay techniques. The soil landscape modeling technique involves the following steps: 1) collection of soil and landscape information from a representative training area, 2) calibration and verification of soil-landscape relationships using multivariate statistical techniques, 3) application of the models to a digital geographic data base to produce soil property maps. This technique has been used in central Pennsylvania, U.S.A. to produce soil property maps with comparable accuracy to existing soil survey maps. -from Authors
