Abstract
 Representation of Change in GIS Track: New Technology and System Integration Author(s): Tony Turner Current GIS has limited capabilities in modeling and visualizing time-varying phenomena such as moving objects and changing boundaries. These limits are partly conceptual, partly methodological and partly technical. Conceptually, they derive from the ontological view of change in the attributes of attributes or locations, and the epistemological view of representations as static and passive reflections of a given reality. Methodologically, they are an effect of the cartographical view of change as the difference between snapshots rather than the accrual of change from state to state. Technically, they have to do with the technical origins and transitions of GIS that apply changes to relations rather than scenes or situations. This presentation explores and demonstrates prototype workarounds that enhance GIS capabilities by drawing upon ideas and techniques from agent-based modeling and visualization software and proposes shifts at the conceptual, methodological and technical levels.
