Metadata Summary

Originator	Metropolitan Council
Abstract	This dataset contains both line and polygon shape files for both 100 meter and 1000 meter US National Grid cells. The US National Grid is an FGDC map presentation standard (FGDC-STD-011-2001). These datasets were created to match the location reference system used by that standard. The reference system is based on NAD 83 UTM Coordinates and the Military Grid Reference System. For more information on the USNG visit these helpful resources: http://www.fgdc.gov/usng - FGDC USNG Site includes links to an executive summary, the standard itself, and other useful references. http://mississippi.deltastate.edu/ - Delta State University USNG page includes links to statewide USNG downloads, learning materials, and ways to get involved in USNG promotion. http://www.esri.com/software/arcgis/extensions/usng/index.html - ESRI provides a free extension to ArcMap that facilitates the use of the National Grid.

Section 2	Data Quality Information	Top of full metadata	Top of page
Attribute Accuracy	This is a calculated dataset. Attributes supplement the spatial information for labeling and identification purposes. Attribute accuracy has not been measured, but is presumed correct.
Logical Consistency	The dataset is topologically 'clean'.
Completeness	Entire seven county geographic area is covered.
Horizontal Positional Accuracy	This dataset was calculated mathematically to represent the US National Grid at 100 meter and 1000 meter grid cell sizes. Gridlines are accurate to less than one tenth of a meter.
Lineage	Polygon layer attribute schema was taken from a National Grid dataset at 1000 meters covering the state of Minnesota downloaded from Delta State University. Polygons were constructed with ArcMap. Lines were derived from polygons.
