Formal models for incremental ontologies are needed in geographic information systems. While there are methods to describe ontologies for a certain purpose, it is still an open question, how to link different geographic ontologies. Observing children in a sandbox can motivate a new way of designing dynamic spatio-temporal ontologies. Contemporary developmental psychology provides evidence that knowledge about the world is acquired in piecemeal fashion. Infants form theory like concepts of the world that are revised in the light of new evidence [12]. We take these findings to build multi tiered ontologies grounded in children's spatial experience. Questions of how to structure and connect the ontologies will be addressed. The formalization of spatial concepts are investigated in an agent based approach using an algebraic framework.
