MGRS Military Grid Reference System (MGRS) Coordinate of the Facility. The MGRS is the geocoordinate standard used by NATO militaries for locating points on the earth. The MGRS provides a means to represent any location on the surface of the Earth using an alphanumeric string. Hierarchical references are based on the Universal Transverse Mercator (UTM) coordinate system. The MGRS is used for the entire earth. http://mgrs-data.org/

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. For more information regarding
scale and accuracy, see our webpage at:

DATA LINEAGE SUMMARY:
In 2012 the FCC stopped releasing tower and antenna locations as spatial 
data. Data layers are available as databases with associated .dat files. 

GeoPlan downloaded the Antenna Structure Registrations from 
http://wireless.fcc.gov/antenna/index.htm?job=uls_transaction&page=weekly in 
August 2019. During the QA/QC process GeoPlan performed the following steps:

- Opened and formatted the CO.dat file in Excel.  Added field names 
  using the FCC Database Field Definitions File: http://wireless.fcc.gov/uls/documentation/patower-2.xls.  
  Saved coordinate fields as LATD, LATM, LATS, LAT_DIR, LOND, LONM, 
  LONS, and LON_DIR
- Saved the CO.dat file to a CSV and Exported to .dbf using ArcMap.
- Filtered .dbf to contain only records located in Florida. (Using field Structure_State
  Code from RA.dat
- Added LATDD and LONDD fields as type = double
- Used field calculator to convert coordinate fields from DMS to DD. The 
  equation for latitude was:
	( [LATS] /3600) + ( [LATM] /60) + [LATD]
  The equation for longitude was:
	( [LONS] /3600) + ( [LONM] /60) + [LOND]
- Generated XY data using the LATDD and LONDD fields.  The projection
  was defined as WGS 1984.
- Exported XY events to shapefile.
- Fields  LATD, LATM, LATS, LAT_DIR, LOND, LONM, LONS, and LON_DIR
  were deleted.
- Projected the new shapefile to NAD83 HARN using the
  WGS_1984_(ITRF00)_To_NAD_1983 + NAD_1983_To_HARN_Florida transformation

- Opened and formatted EN.dat and RA.dat files in Excel. Added field
  names using the FCC Database Field Definitions File and previous fgdl versions of antreg. Deleted
  fields not present in previous versions.
- Saved the EN and RA dat files as CVS files and exported to .dbf files using ArcMap.
- EN and RA .dbf files brought into ArcMap and joined with the antreg
  feature class using REGNUM field. 
- Edited the feature class attribute table to match previous fgdl versions.
- Added field MGRS by using the Convert Coordinate Notation tool and choosing
  output coordinate format as MGRS.
- Added field GOOGLEMAP by concatenating:
  https://www.google.com/maps/place/ and the MGRS ID
- Added descript field based on Entity from EN.dat file.
- Added FGDLAQDATE based on the date GeoPlan acquired the data.
- Restructured table and uppercased all fields.
- 5 records did not have spatial information and were removed. These records were
  REGNUM = 1020589, 1035349, 1035350, 1035351, 1049473

Field Changes

- Previous fields LAT_DMS and LON_DMS have been renamed to LAT and LON.
- Previous fields DD_TEMP and DD_TEMP0 have been renamed to LATDD and
  LONDD.
- Removed fields LAT_DIR and LON_DIR

Notes:
When the FCC generated this data set spatially in the past they limited the 
lat/long fields to 4 decimals. Now that we are generating the spatial locations 
the decimals have been left to the default value of the field type of double. 
The result is a visible shift of 1-3 meters.
