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.

Functions to automate downloading geospatial data available from
several federated data sources (mainly sources maintained by the US Federal
