Spatial Decision Support Systems: a conning of age

Decision Support Systems (DDS) have developed to exploit Information Technology (IT) to assist decision-makers in a wide variety of fields. The need to use spatial data in many of these diverse fields has led to increasing interest in the development, of Spatial Decision Support. Systems (SDSS) based around the Geographic Information System (GIS) technology. Tlie paper examines the relationship between SDSS and GIS and suggests that SDSS is poised for further development owing to improvement, in technology and the greater availability of spatial data.
