SECTION 1: Identification Information
Originator: | Minnesota Department of Transportation, Survey and Mapping | |
Title: | DOT Basemap Roads - All Types | |
Unique Identifier: | 30000005 | |
Abstract: | This data set contains roadway centerlines for roads found on the USGS 1:24,000 mapping series. Those roadways that are Interstate, Trunk Highway, or CSAH (county state/aid Highway) are current through the 2000 construction season. Other roads, if not updated, are depicted as shown on the published quadrangle. | |
Purpose: | Basemap preparation, cartographic products, registration, control | |
Usage Tips: | This coverage is intended to be a single source of data for roadways in Minnesota. It contains road information for a variety of road classes (which also exist as separate datasets). | |
Time Period of Content: | 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. This data layer was updated as recently as January 2001 using the most up-to-date available information. | |
Progress: | Complete | |
Maintenance Frequency: | Yearly | |
Spatial Extent of Data: | Statewide | |
Bounding Coordinates: | E = -89 W = -97.5 N = 49.5 S = 43 |

SECTION 2: Data Quality Information
Attribute Accuracy: | dotrdln3.aat: Unknown. | ||
Logical Consistency: | Data have been topologically structured and verified. | ||
Completeness: | Data are complete statewide, and include all road classes from residential streets to interstate highways. | ||
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 | ||
Distance Resolution: | No information Available | ||
Lineage: | Attribute Lineage: dotrdln3.aat: Attributes were derived from data present on MNDOT's web data distribution site located at http://rocky.dot.state.mn.us/BaseMap/. The files were downloaded by MNDNR on 8/24/2001. The data as downloaded from MNDOT were found to have inconsistencies in the attributes associated with the road features between tiles. There is a group of attributes that are documented by MNDOT which existed within each tile. However, many tiles included extraneous, undefined fields, or duplicated fields within the same table. Changes made by MNDNR include: a) Redefined original field CODE from a 2 place character field to ROAD_CLASS as a 2 character integer field. This change was made to maintain consistency with the current road data in the DNR Core Library. b) Dropped COUNTYNAME Field. This information can be derived by joining with base table of names using the COUN field. c) Redefined COUNTY_NUM field to correspond to existing department guidelines as COUN field with a 2 place integer field. d) Redefined MUNI_MCD field from a 4 place character field to a 5 place integer field and renamed to MCD_CODE in anticipation of the new municipal and township coding scheme. e) TIS_CODE - This field was dropped. It was determined to be of low value to DNR Staff and could be regenerated from the CODE,COUN,MCD_CODE, and Road_Num fields. f) GIS_ROUTE - Dropped field. g) RDWY_NAME - Dropped field.
