Geographic information systems (GIS) have developed in response to a range of needs, and provide highly structured environments for working with particular classes of information. The environment and structure of a GIS is defined by its data model; the paper reviews the basic data models of GIS. The needs of discrete transportation modeling have led to a number of extensions of the basic data models. Further necessary extensions are identified. The paper ends with a discussion of appropriate strategies and future directions.
