Functions to automate downloading 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 (1 and 1/3 arc-second; USGS); The National Hydrography Dataset
(USGS); The Soil Survey Geographic (SSURGO) database from the National
Cooperative Soil Survey (NCSS), which is led by the Natural Resources
Conservation Service (NRCS) under the USDA; the Global Historical
Climatology Network (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 (DAAC); the
International Tree Ring Data Bank; the National Land Cover
Database (NLCD); the Cropland Data Layer from the National Agricultural
Statistics Service; and the PAD-US dataset of protected area boundaries
from the USGS.
