Information retrieval with large-scale geographic data bases

Published: 11 November 1971 Publication History

Abstract

There has been growing interest in dealing with large-seale geographic data bases because of the growing capacities of computer systems and because of the increasing interest in environmental and social systems. This paper outlines the problems associated with these data bases from data acquisition to simulators and information retrieval. It outlines an overall approach to the problem using polygons, point data, and common coordinate systems. It explains a method of grid independent data observation. It also deals with a variety of specific problems of file management and information handling which arise in large-scale information systems dependent on data of a two-dimensional structure, as opposed to data of a linear or hierarchical structure.
