The USNG is an alpha-numeric reference system that overlays the UTM coordinate system. This is a polygon feature data layer of United States National Grid (1000m x 1000m polygons ) constructed by the Center for Interdisciplinary Geospatial Information Technologies at Delta State University with support from the US Geological Survey under the Cooperative Agreement 07ERAG0083. For correct display, please set the base coordinate system and projection such that it matches the UTM zone for which these data were constructed using the NAD 83 datum. Further information about the US National Grid is available from www.fgdc.gov/usng and a viewing of these layers as applied to local geography may be seen at the National Map, www.nationalmap.gov.Fields to be considered:GZD: Grid Zone Designation -identifies the longitude zone number and the latitude band letter; SQID: 100,000 Meter Square ID -indicated the 100,000-meter square that is specific to the GZD.resources.arcgis.com/en/help/localgovernment/10.2.... edited 08/2014
