Abstract

One of the most important problems of agriculture soil science and natural resources in Iran is the lack of information of ecosystems so that the degradation of water, soil and vegetation potential leads to desertification. The main purpose of this study was to investigate the possibility of using satellite data to determine SOIL TEXTURE by using REGRESSION-MODELING approach. The images were geometrically corrected and used to determine the best band combination to make the false-color composite images. This combination was used to applying unsupervised classifications. Field data gathering was conducted with a stratified random sampling. Points were located by using GPS and 80 surface soil samples were taken. The percentage of sand, silt, clay, and soil SATURATION HUMIDITY of each sample was determined. Some analysis such as PCA and making the various soil indices were done on the images. Multivariate, linear regression was applied to produce some models to develop the results of sample analysis to the entire surface of the study area. Produced maps were re-grouped in the classes considered for the soil parameters. By combination of three maps of sand, silt and clay, SOIL TEXTURE map was developed in four major classes with the logic of Boolean algebra. The accuracy table was prepared in accordance of the produced maps with the ground realities. High KAPPA COEFFICIENT indicates a high potential of satellite data to produce maps of soil science with a high precision. This method can be fast and useful, in studies of desertification, combat desertification and controlling methods.
