Decision Support Mapping
Definition
Decision Support Mapping is the use of GIS to assist decision-makers in understanding spatial data and identifying optimal solutions based on various criteria. These maps combine data visualization, analysis, and multi-criteria evaluation tools to help guide planning, investment, policy, and emergency response. They are tailored to highlight areas of opportunity, risk, or need based on user-defined goals or scenarios.
Application
In urban planning, decision support maps help choose development sites based on zoning, transportation access, and land cost. In conservation, they identify high-biodiversity areas under threat. In disaster response, they show evacuation routes and shelters. GIS platforms integrate analytical models, overlays, and dashboards to create interactive maps that support stakeholder discussion and resource allocation. These maps often use scoring, weighting, and suitability models to present ranked options or recommended paths forward.
