2US 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
3Introduction 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
4US 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...
5Florida 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
6FEMA Adopts the USNG
- Near term priority approved by Administrator
Fugate - Establish a standard for FEMA operational maps
using the National Grid
7Introduction 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
8Whats wrong with current systems?
- We already have
- Latitude/Longitude
- Township/Range/Section
- Street Address and Zip
- Bingo Grids
9Latitude/Longitude
- Multiple formats are confusing
- DD -85.990151, 30.272240
- DM -85 59.409089, 30.16.334386
- DMS 85 5924.545W, 30 1620.063N
- All the same location!!!
10 How far is a second anyway?
- What is the distance from.
- 85 5924.545W, 30 1620.063N
- To here.
- 85 5926.292W, 30 1614.546N
11Township/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
12Township/Range/Section
- But a perfect section really doesnt exist
- irregular in coastal areas
- too large to meet needs of ground crews
13Street Address and Zip
- Problematic due to
- rural routes
- post office boxes
- House numbers missing or obscured
14- What do you do when the SIGNS are gone?
15- What do you do when the ROADS are gone?

19Introduction 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
20Universal 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
21Military 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
22United 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
23USNG
- 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.

25Introduction 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
26How 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
27Truncate for locality
16R
17R
16R GU 66000 64820
- just like you dont have to dial an area code to
make a local call - all Florida locations will be 16R or 17R
28Truncate for locality
16R
17R
16R GU 66000 64820
- 100,000 meter zone designation may be dropped
when working locally
29Truncate for less precision
16R GU 66000 64820
Locates within 1 meter
66000 64820
Locates within 10 meters
6600 6482
660 648
Locates within 100 meters
Locates within 1000 meters

30USNG
- Easily scaleable
- Pin-point and cell
- based locational reporting
- Grid within a Grid
31Tools for Responders
- GPS
- GeoPDF
- Mapping applications and websites
32Support for USNG
- http//www.floridadisaster.org/gis/usng
- tools and instructions for GIS staff
- FDEMs GATOR
- new mapping website with USNG tools
- FDEPs Incident Mapper
- simple Google Maps mashup with USNG tools
- GeoPDFs
- new PDF formats have GIS capabilities, including
USNG support
33Global 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 wont
34USNG 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 havent chosen
USNG) - You may also choose MGRS with NAD 83 to be the
functional equivalent of USNG
