资源简介：
These datasets each consist of a folder containing a
personal geodatabase of the NHD, and shapefiles used in the HydroDEM process. These files are provided
as a means to document exactly which lines were used to develop the HydroDEMs. Each folder contains a
line shapefile named for the 8-digit HUC code, containing the NHD flowlines that comprise the coastline
for that island. The “hydrolines.shp” shapefile contains the lines that were burned into the DEM. These
lines were selected from the NHD flowlines, with some minor editing in places. The “wbpolys.shp” shapefile
contains the water-body polygons that were selected from the NHD and used in the bathymetric gradient
process. The folders for HUCs 20010000 (Hawaii) and 20020000 (Maui) also contain a “walls.shp” shapefile,
which contains the lines that were superimposed on the surface as “walls.”
