| Abstract | This data set contains centerlines of Federal, State, County and Municipal roads. In 1986, the road centerlines [CENTLINE] were digitized from hand drawn 1:2400 half and 1:1200 quarter section maps. In 1995, the parcel data layer was converted to ArcINFO format and held in the ArcStorm data base. Centerlines were converted in 2005 to an ESRI ArcGIS GeoDatabase. The vector data is updated utilizing positions calculated from plats using coordinate geometry programs. Plated, Public road centerlines are captured within this database. Private roads may not be shown. All graphical lines contain a character based layer name that identifies the different mapping features. The centerlines usually represent the center of the road right of way. Exceptions to this are freeways and large divided highways, which are represented by double lines. The center of physical roadway pavement may or may not represent the center of the road right of way. Road right of ways may taper or change width. There has been no attempt to alter the road centerline to conform to right of way that is not parallel or alters in width. |

| Section 2 | Data Quality Information | Top of full metadata | Top of page | |
| Attribute Accuracy | Attributes held within the GIS graphical database are manually entered by GIS personnel. There are check plots produced to verify information. Line symbology is periodically checked by automated programs to verify consistency. | |||
| Logical Consistency | Graphical elements are not topologically clean. Over shoots and undershoots may be common in this data set. Linework depicted here was not originally intended to create closed boundaries or polygons. However, as the information is updated, the new data sets produced are topologically clean (overshoots or undershoots are not permitted; except in the case of cul-de-sacs). | |||
| Completeness | Entire Ramsey County coverage | |||
| Horizontal Positional Accuracy | Digitized information is generally ± 7 feet; some areas have been found to be ± 30 feet. COGO (coordinate geometry) accuracy generally is ± 1.0 foot. | |||
| Lineage | PROCEDURE: This layer contains a combination of digitized parcel information and parcel data rectified utilizing positions calculated with COGO programs. MAP SOURCE: Digitized from 1 inch = 200 feet 1/2 section maps. ACCURACY: Digitized information is generally ± 7 feet; some areas have been found to be ± 30 feet. COGO (coordinate geometry) accuracy generally is ± 1.0 foot. PROJECTION: Ramsey County Coordinate System |
