Homeland Infrastructure Foundation Level Data Open Data Portal

“This site provides National foundation-level geospatial data within the open public domain that can be useful to support community preparedness, resiliency, research, and more. HIFLD Open represents the initial evolutionary first step to provide online access to HIFLD Data. HIFLD Open provides publicly available datasets previously contained in HSIP 2015. These 270+ public domain datasets consist of both re-hosted public domain data AND when possible, live pointers to dynamic web services direct from the source. Data is available for download in a variety of formats to include: CSV, KML, Shapefiles, as well as access to APIs  – such as GeoJSON, and GeoService.”
