New York State Geographic Information Systems (GIS) Clearinghouse
The Clearinghouse, operated by the New York State Office of Cyber Security & Critical Infrastructure Coordination, was established to disseminate information about New York's Statewide GIS Coordination Program and to provide access to the New York State GIS Data and Metadata Repository.

Originally developed as part of the Center for Technology in Government's GIS Cooperative Project, the Metadata Repository was created to provide one central location where State agencies and local governments can list the GIS data sets that they have. GIS users can browse the list, or search for specific keywords, to find out what data is available, who holds it, and how it can be obtained. In some cases, users will be able to go one step further, and download the actual data set.

Cornell University Geospatial Information Repository (CUGIR)
CUGIR is an active online repository in the National Spatial Data Clearinghouse program. CUGIR provides geospatial data and metadata for New York State, with special emphasis on those natural features relevant to agriculture, ecology, natural resources, and human-environment interactions.

Geography Network

The Geography Network is a global network of geographic information users and providers. It provides the infrastructure needed to support the sharing of geographic information among data providers, service providers, and users around the world.

Federal Government Geographic Data


A frequent question is how to find administrative boundaries for foreign countries in order to do thematic mapping. Here's a very useful site.


National Historical GIS

The National Historical Geographic Information System (NHGIS) provides, free of charge, aggregate census data and GIS-compatible boundary files for the United States between 1790 and 2010.


Not online (on CD's at Olin Reference), but a very accessible source for 1970 and 1980 boundary files.
