Title
Valley Bottom Polygons 2019 [Pennsylvania] {2025}
Description
This dataset contains polygon shapefiles of valley bottoms derived from the dataset “Pennsylvania Geomorphon LandformMaps 2019”. Valley bottoms are defined by geomorphon types Flat (FL-1), Footslope (FS-8), Valley (VL-9), and Pit (PT-10) within a buffer of 300 m on either side of the stream network in the dataset “Pennsylvania Stream Polygons 2019”. Final polygon boundaries were cleaned using iterative boundary expanding and shrinking, and regions smaller than 10,000 square meters were eliminated. This project was funded by the Pennsylvania Department of Environmental Protection (PADEP) through its Water Program. April 2025.
