USNG Marker Sign on Trail

Welcome to the USNG Store!

This store offers products which support implementation of the U.S. National Grid (USNG). 

Products offered include Emergency Location Markers (ELMs), ELM Repair Stickers, USNG Romer Cards, and more.  We even have a USNG T-Shirt so you can show your USNG Pride!

Emergency Location Markers (ELMs), as shown at right, have been in development for over four years. Throughout that process, efforts were guided by input from first response and geospatial experts who participated in national, state and local focus groups.

USNG ELMs offer a way for communities to mark locations such trail intersections, camp sites, buildings, boat landings, and other response locations with a marker that works with GPS, is location specific, unique across jurisdictions, and is nationally consistent. 

Please do not hesitate to contact us if you have questions, would like help with the ordering process, or just want to talk USNG. You can also learn more about the USNG in general at our U.S. National Grid Information Center
