Description:

Abstract:

This layer represents a 1,000 by 1,000 meter United States National Grid (USNG) for those portions of Florida falling within the NAD83 UTM 16 N zone. The USNG is an alpha-numeric reference system based on the UTM coordinate system and is similar to the Military Grid Reference System. Use of the USNG ensures a uniform grid mapping and positional reporting system for search and rescue, emergency planning, response, and recovery.

Purpose:

The grid serves as a common means for providing locational information in relation to USNG coordinates.

How to Read a United States National Grid (USNG) Spatial Address <http://www.fgdc.gov/usng/how-to-read-usng/index_html> ---------------------------------------------------------------
The USNG is an alpha-numeric reference system that overlays the UTM coordinate system. A USNG spatial address is broken down into three parts, the; - Grid Zone Designation; for a world-wide unique address. - 100,000-meter Square Identification; for regional areas. - Grid Coordinates; for local areas.
4 digits - 2306 - locates a point with a precision of 1,000-meters (a neighborhood size area). 6 digits - 234064 - locates a point with a precision of 100-meters (a soccer field size area). 8 digits - 23480647 - locates a point with a precision of 10-meters (the size of a modest home). 10 digits - 2348306479 - locates a point with a precision of 1-meter (within a parking spot).
To review, we can see a complete US National Grid spatial address contains three parts as we drill down to a unique location, 18S UJ 23480647 - Grid Zone Designation (i.e. 18S). - 100,000-meter Square Identification (i.e. UJ ). - Grid coordinates of some even number of digits ranging from 2 to 10 (i.e. 23480647 In this case, eight digits identify a place of about the size of a modest home.). You always read right, then up when plotting coordinates.
A spatial address is customarily written as a single string of values. Note how the horizontal datum (NAD 83) has been included: USNG: 18SUJ23480647 (NAD 83)

Floridadisaster.org --------------------------------------------------------------- In an effort to standardize maps in Florida for both emergency and other operations, the State Fire Marshal, as the coordinating agency for search and rescue under the State Comprehensive Emergency Management Plan, and the Division of Emergency Management are embarking on a program to adopt the US National Grid (USNG) as the standard in Florida. This project will ensure a uniform grid mapping system across cities and counties in Florida, and will match the system used by the National Guard, the US Coast Guard and the US military when they are deployed into our state.
Florida’s unique geography of miles of coastlines, multiple river corridors, and large watersheds make the use of the common Township/Range/Section grid (PLSS) all but impossible except for a handful of inland counties. As the grid approaches wetlands, river corridors and the coast line, sections become irregular in shape and can be significantly larger than the typical square mile, which is too large to accommodate the needs of ground crews.
Adoption of a national grid system has been identified as ‘critical’ in a number of after action reports, investigations and studies dating as far back as Hurricane Andrew. FEMA, DHS, the National GeoSpatial Intelligence Agency, and the Federal Geographic Data Committee all promote the adoption of the USNG.
Grid cell values are unique and sequentially numbered.

Process_Description:

The University of Florida GeoPlan Center produced this grid in an ArcMap data viewer with the coordinate system set to NAD_83_UTM_Zone_16N. A 1,000-meter by 1,000 grid was generated, using the XTools Fishnet function and covering the area of Florida contained within the UTM 16 N zone. Overlap was included for use in neighboring areas.
Next the XTools Add XY function was used to produce X and Y coordinates for each polygon.
Added fields: X_LWRLFT, Y_LWRLFT, GRID100K, GRID10K, GRID1000M, LABEL, DESCRIPT, FGDLAQDATE, and AUTOID.
Calculated the AUTOID field as follows; [FID] + 250,001
Created Centroids for the 1000M Grid and spatially joined it to the existing usng_fl_10k_utm16.shp Grid.
Joined the Centroids with the 10K Grid information back to the 1000M Grid, via a table join based on AUTOID.
Calculated the GRID100K field based on the joined GRID100K field from the Centroids.
Calculated the GRID10K field based on the joined GRID10K field from the Centroids.
Calculate X_LWRLFT and Y_LWRLFT values as follows; Round ( [XCOORD] - 500, 0 ) Round ( [YCOORD] - 500, 0 ) After these calculations, the XCOORD and YCOORD fields may be deleted.
Calculate GRID1000M as follows; Mid ( [X_LWRLFT] , 2, 2 ) + " " + Mid ( [Y_LWRLFT] , 3 ,2 )
Calculate LABEL as follows; [GRID100K] + " " + Mid ( [X_LWRLFT] , 2, 2 ) + Mid ( [Y_LWRLFT] , 3 ,2 )
Calculated DESCRIPT based on LABEL.
After field calculations were completed the join was removed.

Process_Description:

The University of Florida GeoPlan Center updated the dataset on May 5th, 2009.
Features falling completely outside the UTM Zone 16R were removed and a clip function was used where features fell withing both the UTM ZONE 16R and 17R to remove overlaping features between the two zones.
The DESCRIPT field was updated by adding the UTM Zone designation to the front of the feature description. I.E. - "16R" & [LABEL]

GIS data available in FGDL is collected from various state, federal, and other agencies (data sources) who are data stewards, producers, or publishers. The data available in FGDL may not be the most current version of the data offered by the data source. University of Florida GeoPlan Center makes no guarantees about the currentness of the data and suggests that data users check with the data source to see if more recent versions of the data exist.
Furthermore, the GIS data available in the FGDL are provided 'as is'.

A note about data scale:
Scale is an important factor in data usage. Certain scale datasets are not suitable for some project, analysis, or modeling purposes. Please be sure you are using the best available data.
1:24000 scale datasets are recommended for projects that are at the county level. 1:24000 data should NOT be used for high accuracy base mapping such as property parcel boundaries. 1:100000 scale datasets are recommended for projects that are at the multi-county or regional level. 1:125000 scale datasets are recommended for projects that are at the regional or state level or larger.
Vector datasets with no defined scale or accuracy should be considered suspect. Make sure you are familiar with your data before using it for projects or analysis. Every effort has been made to supply the user with data documentation. For additional information, see the References section and the Data Source Contact section of this documentation.
