Geographic data base image processing at Mississippi State

A geographic image as stored in a computer is simply data that can be processed to array form which, when displayed, represents a twoor three-dimensional image. Generally, several images, related by a common geographic location, are needed to provide end users, that is, persons involved in cartographic, land management, and other geographic applications, with adequate information. The reasons for maintaining related geographic images in a common data bank are much the same as those for storing any related data in such a form. The need to access several images at one time dictates the need for centralized storage. Also, an image data base allows independence of image processing functions from image data while at the same time reducing the overhead associated with maintaining multiple files.
