  • ENTITY-RELATIONSHIP MODELING of SPATIAL DATA for GEOGRAPHIC INFORMATION SYSTEMS Hugh W
    ENTITY-RELATIONSHIP MODELING OF SPATIAL DATA FOR GEOGRAPHIC INFORMATION SYSTEMS Hugh W. Calkins Department of Geography and National Center for Geographic Information and Analysis, State University of New York at Buffalo Amherst, NY 14261-0023 Abstract This article presents an extension to the basic Entity-Relationship (E-R) database modeling approach for use in designing geographic databases. This extension handles the standard spatial objects found in geographic information systems, multiple representations of the spatial objects, temporal representations, and the traditional coordinate and topological attributes associated with spatial objects and relationships. Spatial operations are also included in this extended E-R modeling approach to represent the instances where relationships between spatial data objects are only implicit in the database but are made explicit through spatial operations. The extended E-R modeling methodology maps directly into a detailed database design and a set of GIS function. 1. Introduction GIS design (planning, design and implementing a geographic information system) consists of several activities: feasibility analysis, requirements determination, conceptual and detailed database design, and hardware and software selection. Over the past several years, GIS analysts have been interested in, and have used, system design techniques adopted from software engineering, including the software life-cycle model which defines the above mentioned system design tasks (Boehm, 1981, 36). Specific GIS life-cycle models have been developed for GIS by Calkins (1982) and Tomlinson (1994). Figure 1 is an example of a typical life-cycle model. GIS design models, which describe the implementation procedures for the life-cycle model, outline the basic steps of the design process at a fairly abstract level (Calkins, 1972; Calkins, 1982).
