What This Source Covers
Elevation contour lines with feature codes and elevation values from the county contour layer.
This source supplies terrain-reading context for steep or irregular municipalities where parcel and road views are not enough.
Why Someone Would Open This Page
This source appears on 120 of the 219 mapped place pages in the Allegheny County section, including 92 borough and township pages and 28 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 016 – Contours in Findlay Twp. as the example area. Dense sources use a reasonable slice; lighter sources use the full sample area.

Publish-time contour slice built directly from the live source table because the full contour route is unusually heavy on the current stack.
