Multi-Criteria Modeling in GIS For Optimal SitesAnalytic Hierarchy Process (AHP) For Optimal SitesRelated ArticlesMulti-criteria modeling in GIS has proven useful for locating optimal areas within Colorado. In this case, layers of data include wind potential, solar potential, distance to transmission lines, distance to cities, population density, distance to roads, type of land cover, and if the area is on federal lands (i.e., lack of desire to build energy resources in these lands). Using ArcGIS, the study scaled the layers and weighted their relative worth and then applied them in the multi-criteria model. Results show greater benefits of wind farms in the northeast part of the state relative to other regions, while solar farms are best placed east of Denver.Get price
