What is Multi Criteria Evaluation?
Multi-criteria assessment (MCA) is a decision-making tool used to evaluate problems when one is faced with a number of different alternatives and expectations and wants to find the best solutions with regard to different and often conflicting objectives.
What is Analytical Hierarchy Process in Arcgis?
Analytic hierarchy process (AHP) is a classical land suitability analysis procedure, which gives a systematic approach in making proper decisions for site selection. It also suggests the integration of the GIS-based land suitability model for site selection (Mendoza 1997).
How do you do a multi criteria analysis in GIS?
GIS-MCDA steps
- Define you problem, goal or objective.
- Determine the criteria and the constraints.
- Transform the values onto a relative scale.
- Weight the importance of each criteria in regards to the objective, and in respect to each other.

What is spatial multi criteria decision analysis?
Multi-criteria analysis (MCA) is a technique used to consider many different criteria when making a decision.

It allows the alternative solutions being considered to be ranked in order of suitability.

What is spatial multi-criteria decision analysis?
How do GIS help decision making?
A GIS aids the decision-making process by integrating and displaying data in an understandable form. Furthermore, a GIS is used to analyze relationships among different kinds of data (e.g., environmental and health data). Hence, using a spatial decision-support system is not simply a descriptive exercise.
