United States National Grid (USNG) in Florida Richard Butgereit

2 Florida Adopts the USNG USNG was officially adopted by the Florida Fire Chiefs Association FDEM to adopt the USNG in the States CEMP Updates of GIS/Maps in the 11 Regional Evacuation Studies include USNG grids Florida Fire College, Florida Fire Chiefs Association, FL National Guard have develop curriculum and instructor manuals Fire College has incorporated an intro module in the Firefighter II curriculum

3 What’s wrong with current systems? We already have… – Latitude/Longitude –Township/Range/Section – Street Address and Zip – UTM

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

5 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

6 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

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

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

9 What do you do when the SIGNS are gone?

10 What do you do when the ROADS are gone?

11 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

12 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

13 16R GU R17R Truncate for locality 100,000 meter zone designation may be dropped when working locally

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

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

16 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

17 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

18 Support for USNG FDEM’s Incident Mapper –simple Google Maps mashup w/ USNG tools Support in GIS Applications “Geo”PDF’s –new PDF formats have GIS capabilities, including USNG support USGS Image Maps

21 USNG in ArcGIS 9.1 USNG National Grid Tools Repackaging of… –Military Analyst –Product line tool set (PLTS) USNG Locational Toolbar Available from ArcScripts –Less complicated, easier to use

22 USNG in ArcGIS 9.2/9.3 Integrated… – Identify Problematic in 9.2 (too much precision), fixed in 9.3 – Go to X,Y Tool – Graticules

23 Military Analyst in ArcGIS 9.2/9.3 USNG coordinates may easily be added to a feature class. NAR-C is proper NAD 83 choice - “North American Reference CONUS”

24 Military Analyst in ArcGIS 9.2/9.3 USNG coordinates added to a feature class.

25 Map Books in ArcGIS 9.2/9.3 Sample county map book easily create in ArcMap

26 Map Books in ArcGIS 9.2/9.3 DS Map Book (free extension to ArcMap) Produce 5,000 m x 4, ” x 11” 1:24,000 scale maps Style guide, templates and video from Delta State University linked from our website

27 USNG in Other Applications Delorme’s XMAP GeoPDF Dolph Maps New USGS Quad Maps The National Map
