Homeland Infrastructure Foundation-Level Data (HIFLD)
Homeland Infrastructure Foundation-Level Data (HIFLD) is a U.S. Department of Homeland Security program that provides national geospatial datasets describing the location and attributes of critical infrastructure across the United States. Datasets cover sectors such as hospitals and public health facilities, emergency medical and fire services, law enforcement, energy and utilities, transportation, and communications. The data are distributed as an ArcGIS Hub open-data catalog with downloads in formats including CSV, GeoJSON, KML, and shapefile, and via GeoServices/WMS/WFS APIs. HIFLD is an upstream source of the KnowWhereGraph.
