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

Florida Adopts the USNG• FFCA adopts through 2010

Statewide Emergency Response Plan

• FDEM adopts through 2010 CEMP

• Modules incorporated into Firefighter II curriculum



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 2009 - 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 2001



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 -85.990151, 30.272240

DM -85 59.409089, 30.16.334386

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….

85 59’24.545”W, 30 16’20.063”N

To here….

85 59’26.292”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 766000 3364820

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 66000 64820

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 66000 64820

United States National Grid



Introduction to the USNG How to read USNG

coordinates



16R GU 66000 64820How 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 66000 64820

16R 17R

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 66000 64820

16R 17R

Truncate for locality

• 100,000 meter zone designation may be dropped when working locally



Truncate for less precision…

Locates within 1000 meters66 64

6600 6482 Locates within 10 meters660 648 Locates within 100 meters

66000 64820 Locates within 1 meter

16R GU 66000 64820



USNG

• Easily scaleable

• Pin-point and cell

based locational reporting

• “Grid within a Grid”



Training

• Online videos• EM Academy• CERT Academy• Fire College



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



Support for USNG• http://www.floridadisaster.org/gis/usng

– tools and instructions for GIS staff

• FDEM’s GATOR– new mapping website with USNG tools

• FDEP’s Incident Mapper– simple Google Maps mashup with USNG tools

• GeoPDF’s– new PDF formats have GIS capabilities, including

USNG support
