An archived copy of most of Homeland Infrastructure Foundation-Level Data (HIFLD) from the decommissioned https://hifld-geoplatform.hub.arcgis.com/ page. The USG removed public access to this data portal on 8/25/2025.
Homeland Infrastructure Foundation-Level Data (HIFLD) Archive
The Homeland Infrastructure Foundation-Level Data (HIFLD) program was a trusted resource for infrastructure data across the U.S. It supported policy, emergency management, and research before being discontinued in August 2025. This archive preserves that resource.
The datasets were processed using SeerAI Boson, Databricks, and Apache Sedona and saved in the Parquet format for ease of access directly on cloud object storage. If a dataset included geometry, it was spatially sorted using geohash level 8, which was then removed from the dataset.
Dataset Directory Structure
Many of the original datasets contained multiple collections, and each collection was archived as its own parquet file. To preserve some of the original structure, there is a nested folder hierarchy for datasets and files. Please see below for the structure.
