This is a very simplified map viewer for a portion of Allegehny County's GIS data. It is designed for the public to view key county datasets, inlcluding parcels, address points, streets, voting boundaries, contour lines and map index tiles. The only features that can be clicked for more information are the parcels and address points.
The Search box does not search the County's authoritative address database for address searching but is intended to get the user close to their area of interest and uses a commercially available search engine. The authoritative address information can be found by clcking the structure addess dots. A small portion of the parcel information is provided when the parcels are clicked
