The United States National Grid or USNG is a standardized "language of location" tool for Emergency Responders, GIS professionals,  other government agencies and the general public to communicate accurate location information quickly either by maps, GPS receivers or smartphones.

The USNG can be used for dispatching to incidents, natural disaster operations, search and rescue, missing persons, law enforcement forensic marking of evidence and trail markings.
