Hifld Open GIS Portal Shuts Down

HIFLD Open, a key repository for accessing US GIS datasets on infrastructure, is shutting down on August 26, 2025. This is a revision from a previous announcement, which said that it would be live until at least Sept 30. The portal provided national layers for schools, power lines, flood plains, and more from one convenient location. DHS provides no sensible explanation for dismantling it, other than saying that hosting the site is no longer a priority for their mission (here’s a copy of an official announcement). In other words, “Public domain data for community preparedness, resiliency, research, and more” is no longer a DHS priority.

The 300 plus datasets in Open HIFLD are largely created and hosted by other agencies, and Open HIFLD was aggregating different feeds into one portal. So, much of the data will still be accessible from the original sources. It will just be harder to find.

DHS has published a crosswalk with links to alternative portals and the source feeds for each dataset, so you can access most of the data once Open HIFLD goes offline. I’ve saved a copy here, in case it also disappears. Most of these sources use ESRI REST APIs. Using ArcGIS Online or Pro, and even QGIS (for example), you can connect to these feeds, get a listing in your contents pane, and drag and drop layers into a project (many of the layers are also available via ArcGIS Online or the Living Atlas if you’re using Arc). Once you’ve added a layer to a project, you can export and save local copies.

Adding ArcGIS Rest Server for US Army Corps of Engineers Data in QGIS

If you want to download copies directly from Open HIFLD before it vanishes on Aug 26, I’ve created this spreadsheet with direct links to download pages, and to metadata records when available (some datasets don’t have metadata, and the links will bring you to an empty placeholder). Some datasets have multiple layers, and you’ll need to click on each one in a list to get to it’s download page. In some cases there won’t be a direct download link, and you’ll need to go to the source (a useful exercise, as you’ll need to remember where it is in the future). Alternatively, you can connect to the REST server (before Aug 26, 2025) in QGIS or ArcGIS, drag and drop the layers you want, and then export:

I’m coordinating with the Data Rescue Project, and we’re working on downloading copies of everything on Open HIFLD and hosting it elsewhere. I’ll provide an update once this work is complete. Even though most of these datasets will still be available from the original sources, better safe than sorry. There’s no telling what could disappear tomorrow.

The secure HIFLD site for registered users will remain available, but many of the open layers aren’t being migrated there (see the crosswalk for details). The secure site is available to DHS partners, and there are restrictions on who can get an account. It’s not exactly clear what they are, but it seems unlikely that most Open users will be eligible: “These instructions [for accessing a secure account] are for non-DHS users who support a homeland security or homeland defense mission AND whose role requires access to the Geospatial Information Infrastructure (GII) and/or any geospatial dashboards, data, or tools housed on the GII…“
