Geographic Data Processing

This survey attempts to provide a umfied framework for the constituent elements-originating In numerous and diverse disciplines--of geographical data processing systems. External aspects of such systems, as perceived by potential users, are discussed with regard to extent, coordinate system and base map, range of applications, input/output mechanisms, computer configuration, command and interaction, documentation, and administration.The internal aspects, which would concern the system designer,

To provide concrete examples, ten representative geographic data processing systems, ranging from automated cartography to interactive decision support, are described. In conclusmn, some comparisons are drawn between geographmal data processing systems and their conventional business-oriented counterparts. Range and township scheme of geocoding.
