Linkage Mapper

Linkage Mapper uses GIS maps of core habitat areas and resistances to identify and map linkages between core areas. The tool identifies adjacent (neighboring) core areas and creates maps of least-cost corridors between them. It then mosaics the individual corridors to create a single composite corridor map.
