#### Description

The Physiography dataset represents the spatial intersection of landforms
(available in EE as ERGo/1_0/US/landforms) and lithology (available in EE
as ERGo/1_0/US/lithology) data layers. It provides 247 unique combinations
out of a possible 270. The values for each type are formed by concatenating
the landform and lithology types (e.g., 1101 is "Peak/ridge" landform on
"carbonate" lithology). This data layer is sometimes referred to as
characterizing "land facets".

The landforms layer is based on the USGS's 10m NED DEM (available in EE
as USGS/NED). The lithology layer is not basen on any DEM.

This dataset is provided just for the US, because of the availability
of the lithology data layer, though these data are likely available for
other countries.
