get_wbd

<code>get_wbd</code> returns an <code><a href="https://r-spatial.github.io/sf/reference/sf.html">Simple Feature</a></code> collection of the HUC 12 regions within
the specified <code>template</code>.

Download geospatial data available
from several federated data sources (mainly sources maintained by the
US Federal government). Currently, the package enables extraction from
nine datasets: The National Elevation Dataset digital elevation
models (<https://www.usgs.gov/3d-elevation-program> 1 and 1/3 arc-second;
USGS); The National Hydrography Dataset
(<https://www.usgs.gov/national-hydrography/national-hydrography-dataset>;
USGS); The Soil Survey Geographic (SSURGO) database from the National
Cooperative Soil Survey (<https://websoilsurvey.sc.egov.usda.gov/>; NCSS),
which is led by the Natural Resources
Conservation Service (NRCS) under the USDA;
the Global Historical Climatology Network (<https://www.ncei.noaa.gov/products/land-based-station/global-historical-climatology-network-daily>; GHCN), coordinated by National Climatic Data
Center at NOAA; the Daymet gridded estimates of daily weather
parameters for North America, version 4, available from the Oak Ridge
National Laboratory's Distributed Active Archive Center
(<https://daymet.ornl.gov/>; DAAC); the
International Tree Ring Data Bank; the National Land Cover
Database (<https://www.mrlc.gov/>; NLCD); the Cropland Data Layer from the National Agricultural
Statistics Service (<https://www.nass.usda.gov/Research_and_Science/Cropland/SARS1a.php>; NASS);
and the PAD-US dataset of protected area boundaries (<https://www.usgs.gov/programs/gap-analysis-project/science/pad-us-data-overview>; USGS).
