Logical_Consistency_Report:
Data is based on other GIS Data developed and maintained by Allegheny County GIS Staff.
Completeness_Report:
There is parcel data for all of Allegheny County.

Process_Step:
Process_Description:
Digital Parcel Data was collected from a variety of sources including, but not limited to: Duquesne Light, municipalities, COG's, engineering firms, etc. and was edgematched and assembled into a county-wide dataset. The Controller's Office Mapping Section digitized parcels in AutoCAD and assigned MapLotBlock numbers for the following municipalities: Bradford Woods Borough; Collier Township; Findlay Township; Marshall Township; McDonald Borough; North Fayette Township; Oakdale Borough; Pine Township; South Fayette Township. Those files were then added to the master parcel file.
