3_Catchment_area

Catchment Spatial Analysis DataThis dataset contains service catchment areas for cooling center facilities across multiple U.S. states. Each GeoPackage file includes geospatial polygon boundaries representing the geographic coverage area accessible from each cooling center facility. The catchment polygons are defined based on walkable distance thresholds, with attributes including facility names, catchment types, and minimum travel time. The data enable spatial analysis of cooling center service coverage, identification of gaps in accessibility, and assessment of population reach within walkable distances. Files are provided in GeoPackage format with one file per state.
