Components of the NSDI
Since its inception, FGDC has worked to implement the six basic building blocks, or common elements, of the NSDI: metadata, clearinghouse, standards, framework,
geospatial data, and partnerships. Each of these components serves as a
cornerstone in establishing consistency and structure when it comes to
documenting spatial data for everyday applications, as well as in
building a distributed network of producers and users that facilitate
data sharing.
