What This Source Covers
Woodland polygons with nature code, acreage, and shape-area fields from the county wooded-areas source.
This source gives the system a direct wooded-area layer that can be used independently of broader land-use coding.
Why Someone Would Open This Page
This source appears on 217 of the 219 mapped place pages in the Allegheny County section, including 129 borough and township pages and 88 Pittsburgh neighborhood pages. That gives a quick sense of how broadly the layer is used across the county.
