HIFLD Open Data

The Public Environmental Data Partners are committed to preserving and providing public access to federal infrastructure and environmental data. When the original HIFLD Open portal went offline, the Data Rescue Project archived the repository; this catalog hosts that preserved collection and makes it available in modern formats for research, advocacy, policy, and mapping.

Data is available in GeoParquet, PMTiles, geodatabase, and other formats. Browse collections to explore and download.
