What This Source Covers
County street centerline geometry with street names, range fields, ZIP edge fields, and left/right municipality references.
This source gives the explorer street context and supports joins from address points back to their street segments.
Why Someone Would Open This Page
This source appears on 219 of the 219 mapped place pages in the Allegheny County section, including 129 borough and township pages and 90 Pittsburgh neighborhood pages. That gives a quick sense of how broadly the layer is used across the county.
The example below is here to make the source concrete. Instead of talking about the layer in the abstract, the page shows what it actually looks like on the map.
Example Map
This page uses 002 – Street Centerlines in Richland Twp. as the example area. Dense sources use a reasonable slice; lighter sources use the full sample area.
