US National Grid
• Introduction to the US National Grid
– Why do we need to use the US National
Grid?
– How is it similar/differ from other systems?
– How to read USNG coordinates
• Tools for Responders
• Tools for GIS Support Staff

Introduction to the USNG
 Why do we need to use the
US National Grid?
 How is it similar/differ from
other systems?
 How to read USNG
coordinates
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
• USNG was adopted by the FFCA
• FDEM adopted the USNG in the States
CEMP
• Florida Fire College, Florida Fire Chiefs
Association, FL National Guard developed
curriculum and instructor manuals
• Modules incorporated into Firefighter II
curriculum
5
FEMA Adopts the USNG
• Near term priority approved by
Administrator Fugate
• Establish a standard for FEMA
operational maps using the
National Grid

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
11
Township/Range/Section
• But a perfect section
really doesn’t exist
• irregular in coastal
areas
• too large to meet
needs of ground
crews
12
Street Address and Zip
• Problematic due to…
– rural routes
– post office boxes
– House numbers missing or
obscured
13
• What do you do when the
SIGNS are gone?
14
• What do you do when the
ROADS are gone?

coordinates
Universal Transverse Mercator
• 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
20
Military Grid Reference System
• 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
21
United States National Grid
• 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
22
USNG
• it has the advantage of being easily
plotted on USGS topographic maps by
using a simple "right and then up" method
instead of having to plot from right to left
when using latitude and longitude in the
Western Hemisphere. The coordinates
are also easily translated to distance since
they are in meters. Thus the distance
between two coordinates can quickly be
determined in the field.

How to read USNG
16R GU 66000 64820
Grid Zone Designation – for a
world-wide unique address,
identifies the longitude zone
number and the latitude band
letter
100,000 Meter Grid –
identification for regional
areas
Grid Coordinates –
Easting and Northing position

16R
17R
Truncate for locality
16R GU 66000 64820
• just like you don’t have to dial an area
code to make a local call…
• all Florida locations will be 16R or 17R
27
16R
17R
Truncate for locality
16R GU 66000 64820
• 100,000 meter zone designation may be dropped
when working locally
28
Truncate for less precision…
16R GU 66000 64820
66000 64820 Locates within 1 meter
6600 6482 Locates within 10 meters
660 648
Locates within 100 meters
66 64
29
Locates within 1000 meters
USNG
• Easily scaleable
• Pin-point and cell
based locational
reporting
• “Grid within a Grid”

Tools for Responders
• GPS
• GeoPDF
• Mapping applications and websites
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
32
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
33
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
