How to use free BLM maps offline on your iPhone
For US public lands — national monuments, recreation areas, OHV networks, dispersed-camping country — the best maps are often the government's own, and the BLM gives them away: thousands of georeferenced PDFs at blm.gov/maps/georeferenced-PDFs. Here's how to turn them into live offline maps on your iPhone.
Get NomadTracks free — iOS & Android
Find your map on the BLM site
Browse or search the BLM's georeferenced PDF page by state and area. The files are organized by field office and map series — surface management maps show land ownership, which matters for camping legally.
Download on the iPhone
Tap the map link in Safari and use the download arrow; the PDF lands in Files. (On a computer, AirDrop works just as well.)
Import into NomadTracks
Share the file to NomadTracks or import it from the Maps tab. BLM PDFs carry embedded georeferencing, so they align automatically — no setup.
Navigate offline
Enable the overlay and head out: your live position moves across the official land-management map with zero signal. Record your track on it, drop POIs for camps and water.
