US DEM 1-5m Resolution

Ed_ — Tue, 19 Nov 2024 17:32:57 GMT

Does anyone know from where I can download a DEM (1-5m resolution) for the US, Illinois in particular?

I did find one on the USGS website which has DEMs available @1m resolution, but i can't seem to find from where exactly to download it from their website.

1 meter Digital Elevation Models (DEMs) - USGS National Map 3DEP Downloadable Data Collection

Any help on this will be highly appreciated, cheers 🙂

Normally all USGS stuff would be downloaded through the EarthExplorer website but in this case, there's a different web app for that (link here). Look under the Elevation Producst (3DEP).

Yup that does it, thank you 🙂

There are some slivers of IL that are not covered though but it's still pretty good coverage

Sure, no problem. Not my area but it does seem like at least *some* of the gaps may be covered by the Illinois Lidar holdings? That gap along the eastern state border and the southern tip seems available according to this Lidar Status Map from 2024.
