Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Data is based on Allegheny County Base Data which was produced at a scale of 1"=200'. Vector data is reconciled against tabular data contained in the Integrated Assessment System (IAS), Maintained by the Office of Property Assessments (OPA).

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.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Data is based on County Base Data horizontal positional accuracy. Both vector (street centerlines) and raster (digital orthophotography) are used to align parcel outlines correctly.

Quantitative_Horizontal_Positional_Accuracy_Assessment:

Horizontal_Positional_Accuracy_Value:=/- 5 feet

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_Report:

Data is based on county base data vertical positional accuracy.

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.
