USGS 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.
