A Theoretical Framework for GIS-based Spatial Decision Support Systems: Utilization and Performance Evaluation

Suprasith Jarupathirun, Fatemeh Zahedi

Abstract

The spatial analytical capabilities of geographic information systems (GIS) make them good candidates to be used in spatial decision support systems (SDSS). There is little research on utilization and spatial decision performance of GIS-based SDSS. In this paper, we synthesize theories from IS management, organizational behavior, psychology and DSS in developing a conceptual model and subsequent propositions for examining the factors impacting the utilization and spatial-decision performance of GIS-based SDSS.
