Node of the National Geospatial Data Clearinghouse The USGS
node of the National Geospatial Data Clearinghouse is a component
of the National Spatial Data Infrastructure (NSDI). It provides
a pathway to find information about geospatial or spatially referenced
data available from USGS. It encompasses a distributed set of sites
organized on the basis of the USGS's four principal data themes.
The first, Geography, offers the familiar USGS topographic maps
and other geographic products that have long been associated with
USGS. These products typically are of general use across many disciplines
for basemaps and other purposes. As Geographic Information Systems
have come to play an increasingly important role in science, however,
the biology, geology, and water disciplines also have produced important
geographic data sets related to their themes. These thematic products
are best found by discipline.
