Towards a generic foundation for spatial ontology

In this paper we describe the results of our current efforts to establish a foundation for combining spatial ontologies. We draw on the state of the art in computational ontological engineering, ontologies for geographic information systems and qualitative reasoning in order to build a framework within which these, and other, approaches may be placed. The skeleton of the framework is provided by the DOLCE ontology augmented by several important components of Smith’s BFO. We point out the particular importance of including notions of variable granularity, layers and sites in order to do justice to the requirements of practical ontological application. The target applications for our own work are spatial reasoning for robotic systems and natural language interaction.
