summary This paper describes the development of a prototype information system aimed at supporting representation and manipulation of models of urban areas. As a first step, we used aerial imagery to produce accurate digital models of various features of urban areas. The models comprise natural features like terrain data, water and vegetation systems, and man-made features like transportation network, land parcels, and built-up volumes. These data are represented in three dimensions, and they can be further linked with nongraphic attributes stored in an external database schemata. In this paper, we describe the architecture of the prototype system with a particular emphasis on the database aspects, various multimedia data types supported in the system, and operations to query and retrieve the represented data.
