Introduction to the USNG  Why do we need to use the US National Grid?

US National Grid Lessons learned have taught us that standardized grids are needed for positional reporting. As far back as Hurricane Andrew, problems were recognized for emergency managers...

Florida Adopts the USNG

FFCA adopts through 2010 Statewide Emergency Response Plan FDEM adopts through 2010 CEMP Modules incorporated into Firefighter II curriculum

10

Florida CEMP “The State of Florida has adopted the use of the U.S. National Grid (USNG) during response and recovery efforts which allows for both point and area referencing. The SERT utilizes the Grid for designating ground-based areas of operation and dividing the state into scalable grid squares (100,000, 10,000, and 1,000 meters).”

FEMA Adopts the USNG Spring near term priority approved by FEMA Administrator Establish a standard for FEMA operational maps using the National Grid

National Standards National Search and Rescue Committee – specifies US National Grid as primary system Federal Geographic Data Committee – US National Grid Standard since

Introduction to the USNG  How is it similar/differ from other systems?

What’s wrong with current systems? We already have… – Latitude/Longitude – Township/Range/Section – Street Address and Zip – “Bingo” Grids

Latitude/Longitude Multiple formats are confusing DD , DM , DMS 85 59’24.545”W, 30 16’20.063”N All the same location!!!

How far is a second anyway? What is the distance from… ’24.545”W, 30 16’20.063”N To here… ’26.292”W, 30 16’14.546”N

Township/Range/Section Township/Range/Section grid from the Public Lands Survey System is an important and good system… – basis of land ownership records – been in use for over 180 years

Township/Range/Section But a perfect section really doesn’t exist irregular in coastal areas too large to meet needs of ground crews

Street Address and Zip Problematic due to… – rural routes – post office boxes – House numbers missing or obscured

What do you do when the SIGNS are gone?

What do you do when the ROADS are gone?

Developed by the United States Army Corps of Engineers in the 1940s A position on the Earth is referenced in the UTM system by the UTM zone, and the easting and northing coordinate pair. Abbreviated as “UTM” 16R Universal Transverse Mercator

is the geocoordinate standard used by North Atlantic Treaty Organization (NATO) for locating points on the earth. is derived from the UTM grid system, but uses a different labeling convention. Abbreviated as “MGRS” 16R GU Military Grid Reference System

Practically identical to MGRS. Difference is the datum – MGRS uses WGS84, which USNG uses NAD 83 Coordinates reported identical. Abbreviated as “USNG” 16R GU United States National Grid

Introduction to the USNG  How to read USNG coordinates

16R GU How to read USNG 100,000 Meter Grid – identification for regional areas Grid Coordinates – Easting and Northing position Grid Zone Designation – for a world- wide unique address, identifies the longitude zone number and the latitude band letter

16R GU R17R Truncate for locality just like you don’t have to dial an area code to make a local call… all Florida locations will be 16R or 17R

16R GU R17R Truncate for locality 100,000 meter zone designation may be dropped when working locally

Truncate for less precision… Locates within 1000 meters Locates within 10 meters Locates within 100 meters Locates within 1 meter 16R GU

USNG Easily scaleable Pin-point and cell based locational reporting “Grid within a Grid”

Tools for Responders GPS GeoPDF Mapping applications and websites

Global Positioning Systems I have GPS……..why do I need to care about any of this? – USNG can be used with GPS – GPS supplements USNG – USNG will work when your GPS won’t

USNG and GPS Most GPS units explicitly support USNG as an option for units If you choose USNG, you must also choose NAD 83 as your datum (or technically, you haven’t chosen USNG) You may also choose MGRS with NAD 83 to be the functional equivalent of USNG
