U.S. National Grid Location Marker Proposal

The information on this page represents development efforts through September 2010. Subsequent efforts have been managed by the Minnesota nonprofit SharedGeo. Please visit their USNG Emergency Location Markers project page for the latest updates.

To complement the United States National Grid (USNG) method for defining location, a standardized system for marking locations with USNG coordinates is being considered -- it would be used when and where appropriate and desired.

The proposal was developed by the Emergency Preparedness Committee after discussion with experts within and outside of the state.
