Cover title: Final report on computer processing of remote sensing data

This report describes the computer program development carried out by the Regional Computer Center of the Asian Institute of Technology for the classification of the information, recorded on the Computer Compatible Tapes, from the LANDSAT satellites as they pass over Thailand and the Lower Mekong Region. The RECOG computer program package was selected and modified for this development work. Three classification approached employed in the computer are Level Slicing, Euclidean Distance and Maximum Likelihood decision schemes. To demonstrate the capability of the program, which covered reservoir, estuary, deltaic area, mangrove area and road features were selected for the classification. Due to the difficult classification of the small subimages such as road and water way, an additional technique for image enlargement called the cubic convolution interpolation technique was added to the package.
