Functions to automate downloading geospatial data available from
several federated data sources (mainly sources maintained by the US Federal
government). Currently, the package allows for retrieval of five 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 3, available from the Oak Ridge National Laboratory's
Distributed Active Archive Center (DAAC); and the International Tree Ring Data Bank.
Additional data sources are in the works, global soils (HWSD),
MODIS satellite data products, the National Atlas (US), Natural Earth, and WorldClim.
