Nonroad developed land in the United States Pacific Northwest for 2001 summarized for NHDPlus v2 catchments

This spatial data set was created by the U.S. Geological Survey (USGS) to represent the area of non-road developed land within each incremental watershed delineated in the NHDPlus v2 dataset in the Pacific Northwest region of the United States (Hydro Region 17; Major River Basin 7 (MRB7)) in 2001.

本空间数据集由美国地质调查局（U.S. Geological Survey, USGS）编制，旨在表征2001年美国太平洋西北地区（水文区域17；主要流域7，MRB7）的NHDPlus v2数据集中每一处增量划定汇水区的非道路开发用地面积。
