Title | Mn/DOT BaseMap 2001 - Roads |
Abstract | Roads, which represents road centerlines within the state, is a layer of the State of Minnesota BaseMap 2001 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 Roads layer is included in Section 5 of this document - Entity and Attribute Overview. |
Purpose | The BaseMap was developed to fill a need at Mn/DOT for a continuous, statewide GIS base map of the transportation system. |
Time Period of Content Date | 01/01/2001 |
Currentness Reference | The original digitization was done
during the 1990-1995 time period. For any given area, Mn/DOT used the most
recent USGS 7.5-minute quadrangle available at that time. For BaseMap 2001,
the following data layer was updated as recently as January 2001 using
the most up-to-date available information:
