What is USNG?

The United States National Grid (USNG) is a map grid and a corresponding method of identifying cells in that grid. USNG codes can reference grid cells of different sizes depending on the accuracy needed. For example, 33U UU 91899 18914 addresses a 1m x 1m square, and 33U UU 918 189 addresses a 100m x 100m square at the same location. This makes this system perfect for communication locations over radio or phone. While USNG is mostly used by US public safety professionals today it is a worldwide system and not limited to the United States.

 
Tip: The following video What is USNG? from Fire Engineering can give you more insights into this feature.
