This paper presents a knowledge representation approach to modelling and manipulating spatio-temporal data and to grounding a spatio-temporal geographic ontology upon the data. This approach has been developed in the form of a definition-based ontological framework, upon which GIS applications can be developed to perform analysis of geographic phenomena by querying the spatio-temporal database in a more conceptualised fashion. We draw special attention to the representation of geographic features which can change over time, since an appropriate modelling of these dynamic features can provide a natural way of defining other dynamic entities of geographic space, such as events and processes. In addition, the paper discusses some architectural aspects of a GIS which incorporates our semantic model and describes an example of event modelling to illustrate the application of the proposed approach.
