Metadata Summary
Originator  Minnesota Department of Transportation (MnDOT) 
Abstract  State, which represents the state boundary, is a layer of the State of Minnesota BaseMap which consists of a number of individual data layers or themes digitized from USGS 7.5-minute quadrangles. These data layers fall into the following broad categories: transportation system, civil and political boundaries, and surface water. A description of the State layer is included in Section 5 of this document - Entity and Attribute Overview.

Time Period of Content Date  01/01/2003 
Currentness Reference  The original digitization was done during the 1990-1995 time period. For any given area, MnDOT used the most recent USGS 7.5-minute quadrangle available at that time. For BaseMap, the following data layer was updated as recently as January 2003 using the most up-to-date available information:

Title  MnDOT BaseMap - State 
Abstract  State, which represents the state boundary, is a layer of the State of Minnesota BaseMap which consists of a number of individual data layers or themes digitized from USGS 7.5-minute quadrangles. These data layers fall into the following broad categories: transportation system, civil and political boundaries, and surface water. A description of the State layer is included in Section 5 of this document - Entity and Attribute Overview. 
Purpose  BaseMap was developed to fill a need at MnDOT for a continuous, statewide GIS base map of the transportation system. 
Time Period of Content Date  01/01/2003
Currentness Reference  The original digitization was done during the 1990-1995 time period. For any given area, MnDOT used the most recent USGS 7.5-minute quadrangle available at that time. For BaseMap, the following data layer was updated as recently as January 2003 using the most up-to-date available information:

State 

Horizontal Positional Accuracy  Locational accuracy for features derived from USGS 7.5-minute quadrangles cannot be assumed to exceed National Map Accuracy Standards for 1:24,000 scale maps (+/- 40 feet or 12 meters) 
Vertical Positional Accuracy  Not applicable 
Lineage  Data Source: 
1:24,000-scale USGS 7.5-minute quadrangles 

Processing Steps:
During the time period 1990-1995, the BaseMap data layers were digitized from USGS 7.5-minute quadrangles using MicroStation CADD. A total of 1745 quadrangles were digitized. For any given area, MnDOT used the most recent quadrangle available at that time. The digital MicroStation CADD files were converted from State Plane Coordinates to UTM and then converted into ARC/INFO coverages. The ARC/INFO files were merged into statewide, seamless coverages and then attributes were added.
