Details

The raw data were subsetted to the geopackage file msep_hucs.gpkg using the script subset_NHD.R. The subset was further processed into this final form, using the tigris package for state and cartographic boundary delineations, in make_boundaries.R. Both scripts and the subsetted geopackage file are available in the data-raw directory of the package repository at: https://github.com/CMEP-MS/msepBoundaries.
