ABSTRACT
The progress of Geographic Information Systems (GIS) has continued at a rapid pace since its inception in the early 1960s (Longley et al. 2001). However, the synergistic interaction of dynamic new geographic technologies such as real-time GPS/GIS (Richardson 2001), and progress in the development of new models of geographic data representation (Fonseca et al. 2002, Mark et al. 2003) are providing the information fusion capabilities needed to make an intelligent geographical information infrastructure a reality. They already are providing the catalyst for an explosion of loosely linked Geographic Management Systems (GMS), which are relevant to a broad range of stakeholders and applications.
