APPLICATION OF THE SEMIVARIOGRAM TEXTURAL CLASSIFIER (STC) FOR VEGETATION DISCRIMINATION USING SIR-B DATA OF BORNEO

Classification of Shuttle Imaging Radar-B (SIR-B) data from a rainforest-covered portion of Borneo is performed using image texture. The algorithm used is the semivariogram textural classifier (STC). This is a deterministic, supervised parallelepiped type classifier which provides the option of combining textural and radiometric information. Textural information is expressed by the semivariogram function. Radiometric information is conveyed by the mean digital number (DN) value. Results of the classification emulate a previously published map obtained by visual interpretation of the same SIR-B data set.
