Abstract. The use of object-orientation for both spatial data and spatial process models facilitates their integration, which can allow exploration and explanation of spatial-temporal phenomena. In order to better understand how tight coupling might proceed and to evaluate the possible functional and efficiency gains from such a tight coupling, we identify four key relationships affecting how geographic data (fields and objects) and agent-based process models can interact: identity, causal, temporal and topological. We discuss approaches to implementing tight integration, focusing on a middleware approach that links existing GIS and ABM development platforms, and illustrate the need and approaches with example agent-based models.Key words: Object-orientation, Agent-based models, Spatial-temporal modeling, Topology
IntroductionThis paper addresses the representation of both form and process, as spatial data models and spatial process models, respectively, and how relationships between these representations might be structured to better facilitate scientific inquiry and application. Raper and Livingstone (1995)
