Traditional spatial information systems hold only a single state of
the 'real world'. However, geographic phenomena have not only static
but dynamic characteristics. The work described in this paper
contributes to the general research effort toward a generic ontology
of dynamic geographic-scale phenomena and its application to the
provision of modeling, analysis, and retrieval of data in a
spatio-temporal GIS. These issues are addressed in this paper with
reference to dynamic geo-networks, that is, networks embedded
in a (2-dimensional) geographic space. After an introductory and
motivational section, the basic ontological categories of events and
states are discussed. The paper develops these ideas in the context of
flows in dynamic geo-networks, and goes on to discuss the possible
kinds of causal relations. The paper concludes with an overview of the
results and pointers to further research directions.
