U.S. National Grid
The U.S. National Grid (USNG) is a worldwide geospatial coordinate system which facilitates interoperability between GIS, GPS and the basic hand map.
Based on the Military Grid Reference System (MGRS) with subtle improvements, it creates a uniform, easy-to-use methodology for quickly locating points with a
high degree of accuracy. Its use during disasters has been endorsed by FEMA, the Federal Geographic Data Committee, and multiple other federal and state units
of government, as well as virtually all Search and Rescue (SAR) organizations. USNG has been a Minnesota state government geospatial standard since 2009.
