The National Parks dataset September 30, 2019 is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics's (BTS's) National Transportation Atlas Database (NTAD). These are the National Park Service unit boundaries. These park boundaries signify legislative boundary definitions and local park names have been consolidated according to the legislation. The Cape Krusenstern National Monument was subsetted from the all NPS boundaries by importing with the rgdal package as a SpatialPolygonDataFrame object from package sp, and then simplified to a SpatialPolygons object. The R code that creates the data file from raw data can be found at system.file("raw data/polyMaps/create_CAKRboundary.R",package = "ZVHdata"). It was subsequently converted to sf using st_as_sf function.
