Description:

Abstract:: Represents the location the centerline of all roads segments within Wayne County. These segments represent the components of the street system as linear features. Each segment is located approximatley in the center of the roadway.
Purpose:: To locate all roads within the county boundaries to be used in planning and location endevors.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

The database validation routines verify the attribute definitions and valid attribute values for each feature and between features. These routines verify feature attributes and attributes in related database tables. Validation checks include:

a) Item definitions

b) Item values

c) Item uniqueness, if so specified

d) Feature consistency checks as described above

e) Relate cardinality (Verifies a 1:1, 1:M, or M:M relationship between related tables)

Logical_Consistency_Report: Arc Node topology exists.

Completeness_Report:

The WCRDB2 is the derived centerline coverage taken from the County's orthophotography that contains attribute data specific to address matching. The full geographic framework attribute datasets will be available in future releases. Beta 2 contains updated streets and municipality allocation for all the roads.

The WCRDB2 is a product of the conflation project that attributed the streetcl coverage with data from the Michigan Geographic Framework dataset. The coverage will be released in varying stages as components of it are completed. To allow for proper routing procedures, some linework was moved. This caused some segments not to overlay the roads on the photography.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

The creation of these files was based off the Wayne County Orthophotography Project criteria.

One of the following horizontal accuracy requirement industry standards was followed.

1. United States National Map Accuracy Standards, Office of Management and Budget (OMB).

2. American Society of Photogrammetry and Remote Sensing (ASPRS) Accuracy Standards for Large Scale Maps.

3. American Society of Photogrammetry (ASP) Specifications for Aerial Surveys and Mapping by Photogrammetry Methods for Highways.

4. U.S. Department of Transportation (DOT) Surveying and Mapping Manual Map Standards.

5. U.S. Army Corp of Engineers (USACE), Enginerring and Design, photogrammetric Mapping.

6. U.S. National Cartographic Standards for Spatial Accuracy.

The GPS points that were collected to provide additional control for high accuracy analytical aero-triangulation solutions from existing aerial photography. The internal accuracy of the network achieved first order class 1 standards in all station pairings, i.e., the relative horizontal position accuracy between stations in the network does not exceed 10 mm + 10 ppm of the station separation. The GPS network met the current Federal Geodetic Control Subcommittee (FGCS) accuracy standards. The GPS network, based on existing National Geodetic Reference System (NGRS) control, consists of 21 stations of which one is an existing HARN B-order horizontal control point, one is an existing HARN B-order horizontal/first order vertical control point, and one is an existing HARN A-order horizontal/second order vertical control point upon which the network is based.
