Geographic information systems.

Abstract

Geographic information systems are emerging as an effective technology for dealing with complex resource management problems. An examination of the geographic information system environment reveals the major subsystems of data capture, data-base operations, and analysis. Methods of data organization are reviewed with respect to the types of data handled. Different types of systems are discussed as to their relative strengths. Alternative methods of data capture are examined and typical applications presented. Emerging trends in the field are presented and critical issues for the continued development of effective applications are discussed.-Author
