The chapter is on the geospatial decision support systems. Challenges arise when simple GIS is used to support complex problems encountered at higher level, strategic decision-making, and long-term development planning. In this case, SDI can be more valuable. The chapter presents the perspective of information systems for decision support taking into account the following: the levels of decisions and the process of decision making. Trends on the tools and framework for interactive decision support systems are discussed focusing on geospatial decision support systems based on GIS and SDI.
TopBackground
SDIs were initially conceived as a mechanism to facilitate access and sharing of spatial data for use within a GIS environment. Their role has changed in order to support more effective cross-jurisdictional and interagency decision making in priority areas (International Development Research Centre, 2000, Keenan, P., B., Jankowski, P., 2019).
Decision Support Systems
In spatial planning, territorial planning is of fundamental importance. It allows the development of a coherent intervention framework to implement a common ambition by projecting itself into the future. This task must engage the vital forces of the community. However, this operation is very complex: decision support and geographic information systems can facilitate understanding of issues and decision-making.
Thousands of decisions are made each. Each of them is at different hierarchical levels. More or less sophisticated decision support tools exist (linear programming, sales forecasting methods, dashboard, etc. ...), but we will not forget that all the management variables can not be put in equation to the extent that the decision-making process largely obeys very subjective considerations.
