ABSTRACT: Spatial decision support systems (SDSSs) have emerged from the co-evolution of
research in decision support systems (DSSs) and geospatial information systems (GISs).
Because of issues of interoperability and scale, these systems face new challenges and
opportunities in an Internet-connected world. We present a conventional and semantic agent-
assisted view of SDSS capability and discuss current trends in GIS technology relevant to
spatial decision support. We introduce and discuss technologies and methodologies being
developed for the web-based exchange of data and services using semantic agents. A
semantic-web enabled spatial navigation problem is presented and its advantages for
decision-time generation of alternatives are discussed. Finally, we discuss extensions and
