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.
