Abstract

Geographical databases require rich data models to represent geographical entities, relationships between these entities and geometric data. Furthermore, interactive spatial query languages should allow users to pose ad hoc queries in languages close to standards with high level graphical interfaces. This paper shows that a system mixing object-oriented and relational modelling capabilities with an extended SQL to query classes and relations is appropriate for modelling geographical data and interacting between a user and a GIS. Following these lines, a system is currently being implemented on top of an object server as an outcome of the IMPRESS ESPRIT project.
