Spatial decision support is the computational or informational assistance for making better informed decisions about problems with a geographic or spatial component. This support assists with the development, evaluation and selection of proper policies, plans, scenarios, projects, interventions, or solution strategies.
Spatial decision making faces various decision complexities such as
- Spatial nature and temporal development of phenomena and processes;
- Complex multi-dimensional and heterogeneous data describing decision situations;
- Large or extremely large data sets that include data in numerical, map, image, text, and other forms;
- Large number of available alternatives or a need to generate decision alternatives "on the fly" according to the changing situation;
- Multiple participants with different and often conflicting interests;
- Multiple categories of knowledge involved, including expert knowledge and layman knowledge.
