Progress in Spatial Decision Making Using Geographic Information Systems
ByTimothy Nyerges
Pages 14

Where are we with progress in spatial decision making using geographic information systems (GIS)? If you agree with David Cowen who wrote "I conclude that a GIS is best defined as a decision support system involving the integration of spatially referenced data in a problem solving environment" (Cowen, 1988, p. 1554), then perhaps we have amassed a wealth of experience using GIS in a spatial decision making context. If you agree more with Paul Densham who later wrote "current GIS fall short of providing GIA [geographic information analysis] capabilities [for decision making support]" (Densham, 1991, p. 405), then perhaps you believe that GIS has not evolved enough to truly support decision making.
