Ontology specification is a core component of the Semantic Web, and facilitates interoperability among different systems that use distinct models. Developing a spatial ontology will allow many applications that have spatial objects to interact. In this paper, we formalize 2-D spatial concepts and operations into a spatial ontology. We show how these concepts can be realized in Protégé [30]. The Protégé spatial ontology provides spatial built-ins that can be used to provide a spatial dimension to other ontologies when needed. We give some examples of the use of our ontology, which is based on a standard Geometry class hierarchy [23], with a few modifications.
