What This Source Covers
Building polygon outlines with classification and change-related fields from the county PASDA layer.
This layer shows the built envelope of structures and is useful when the parcel view is too coarse for close-in map reading.
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 004 – Building Footprints in Live source window as the example area. Dense sources use a reasonable slice; lighter sources use the full sample area.
Live Example Map
Building Footprints
Live source window / Infrastructure / polygon sample
Publish-time live source slice from the building-footprint layer. The full municipal footprint pages are unusually dense, so this docs example uses a light source window instead of a whole-place render.
