U.S. National Grid
Resources
The U.S. National Grid Standard has been approved as a Minnesota state standard. USNG Maps are available statewide. See a USNG overview brochure.
USNG Location Marker Proposal, v2.3 draft -- public review complete for this version.
The USNG is an effort to interlock GIS, GPS and the basic hand map in a way that creates a uniform, easy-to-use methodology for quickly geo-locating points with a high degree of accuracy. It has been endorsed by FEMA, the Federal Geographic Data Committee, and several other major organizations with an interest in geospatial awareness during disasters.
The items below were compiled by the Emergency Preparedness Committee (EPC) to promote interest and understanding of the U.S. National Grid.
