LOW-COST COMPUTERIZED LAND-USE CLASSIFICATION

A LOW-COST COMPUTERIZED ANALYSIS APPROACH IS INVESTIGATED TO IDENTIFY GENERAL LAND-USE CLASSIFICATIONS FROM A NUMBER OF MULTIFORMAT, NON-REGISTERED, MULTISPECTRAL IMAGES. THIS IMAGERY WAS COMPINED IN THE FOLLOWING MANNER: (1) DAY AND NIGHT THERMAL-INFRARED (TIR); (2) DAY AND NIGHT TIR WITH COLOR-INFRARED FILM; (3) DAY AND NIGHT TIR WITH THOSE CHANNELS OF THE MULTISPECTRAL SYSTEM THAT COVERED THE SAME PORTION OF THE SPECTRUM THAT IS COVERED BY COLOR FILM; (4) DAY AND NIGHT TIR WITH THOSE CHANNELS OF THE MULTISPECTRAL SYSTEM THAT COVERED THE SAME PORTION OF THE SPECTRUM THAT IS COVERED ON COLOR-INFRARED FILM; (5) DAY AND NIGHT TIR WITH ALL EIGHT CHANNELS OF THE MULTISPECTRAL SYSTEM. THE IMAGE DENSITIES FOR SELECTED KNOWN LAND-USE CLASSES WERE PROCESSED THROUGH A FORTRAN PROGRAM AND USED AS A MODEL FOR IDENTIFYING SAMPLE TARGETS OF KNOWN LAND-USE CLASSES. THE EVALUATION WAS PERFORMED TWICE: ONCE WITH THREE BROAD LAND-USE CATEGORIES, AND A SECOND TIME WITH EACH BROAD, CATEGORY SUBDIVIDED BY LANDFORM FOR A TOTAL OF 12 POSSIBLE CATEGORIES. THIS MADE IT POSSIBLE TO DISCRIMINATE AMONG SOIL, VEGETATION AND WATER BASED ONLY ON IMAGE DENSITIES. THE TEST AREA WAS LOCATED IN A SELECTED AREA OF CAMERON PARISH IN SOUTHWESTERN LOUISIANA.
