Description:

Abstract:

This dataset contains street centerlines for vehicular and foot traffic in Allegheny County. Street Centerlines are classified as Primary Road, Secondary Road, Unpaved Road, Limited Access Road, Connecting Road, Jeep Trail, Walkway, Stairway, Alleyway and Unknown. Modified by GDR for the Allegheny County CAD project, October 2008. Data is updated by County staff as changes and corrections are found, on a continuous basis. Updates are sent to PASDA monthly.

Purpose:

Data was developed as part of the effort to establish large scale base data to support a Geographic Information System in Allegheny County

Supplemental_Information:

Data users are welcome to e-mail corrections to this dataset.

Attribute_Accuracy:

Attribute_Accuracy_Report:

Modified by GDR for the Allegheny County CAD project, October 2008.
Data was subject to visual check by County GIS Staff for attribute accuracy.

NOTE: This data is considered to be spatially accurate, but lacking attributes such as address ranges, street names and zip codes, making it inappropriate for geocoding applications.

Logical_Consistency_Report:

Modified by GDR for the Allegheny County CAD project, October 2008.

Completeness_Report:

Modified by GDR for the Allegheny County CAD project, October 2008.
As part of the 2004 update project, mapping was provided covering an area extending 1500 feet beyond the county boundary line. All planimetric, contour and DTM features were delivered in ESRI geodatabase format as County-wide seamless Feature Classes.
