USGS Land Cover Institute: Set of links from the USGS for numerous land cover datasets. Although primarily US data, further down the list there is data for other continents. Atlas of the Biosphere: Mapping the Biosphere: Raster maps of environmental variables including soil pH, potential evapotranspiration, average snow depth, and more.
A hydrological code or hydrologic unit code is a sequence of numbers or letters (a geocode) that identify a hydrological unit or feature, such as a river, river reach, lake, or area like a drainage basin (also called watershed in North America) or catchment.
A water resource region is the first level of classification used by the United States Geological Survey to divide and sub-divide the United States into successively smaller hydrologic units as part of the U.S. hydrologic unit system. This first level of classification divides the United States into 21 major geographic areas, or regions.
