Some concepts and techniques for constructing and using a geographically-oriented urban data base

Abstract This paper describes two projects, established to develop and demonstrate improved computer-based techniques for creating and maintaining a geographically oriented urban data base, and retrieving, analyzing and graphically displaying meaningful information. Functional files of real property and socio-economic data, maintained separately by a variety of governmental departments were integrated, and adapted for use with city maps by coordinate indexing techniques. Methods have been developed to facilitate specifying geographic areas of interest and information desired, and retrieving the relevant records.
