USNG - PIX4Dreact

What is USNG?

The United States National Grid (USNG) is an internationally consistent language of location in a user friendly format. It is a grided reference system that can pinpoint any location on earth at flexible scales using a simple alphanumeric label. For example, 33U UU 91899 18914 identifies a 1m x 1m square, whereas 33U UU 918 189 identifies a 100m x 100m lower resolution square at the same location. While USNG is mostly used by US public safety professionals today it is a worldwide system and not limited to the United States.
