Abstract
The Remote Sensing Section of the Physics and Engineering Laboratory has developed a general purpose image processing system. An overview of the system is given here. Its primary use is the production of special purpose map products from multispectral imagery. Its capabilities include enhancement, rectification, mosaicking, map digitization, automatic relief shading, filtering, restoration, classification and film production. The data base includes images from the LANDSAT and CZCS multispectral scanner satellites, images from an eleven-band aircraft multispectral scanner and a variety of digitized maps.
