Multi-Criteria Decision Analysis, or MCDA, is a useful methodology that can apply to many complex decisions.
Geographic Information Systems multi-criteria decision analysis GIS-MCDA consists of a method to convert and combine spatial data/geographical information and decision-makers criteria to attain evidence for a decision-making process. GIS capabilities are enhanced by MCDA procedures, techniques, and algorithms for structuring decision problems, to design, evaluate and prioritize alternatives.
Integration of GIS and MCDA provides a replicable model, improves communication between project participants or decision-makers, can offer a different perspective of problem and solution, helping to redefine initial specification and/or criteria.
