ABSTRACT
In Chapter 1, we introduced the importance of spatial decision-making processes and explained various terms related to spatial decision support systems (SDSS). The purpose of this chapter is to discuss how SDSS have evolved or progressed from the decision science and geographic information science disciplines. This chapter is organized in three sections. The first section explains some of the major drivers in the evolution of decision support systems (DSS), Geographic Information Systems (GIS), and SDSS. The second section provides background and perspectives on the evolution of SDSS from DSS and GIS. The final section explains the progression of SDSS from simple, stand-alone desktop SDSS to advanced service-based SDSS.
