Which geocoded or geospatial data sets are available to me through the GIA Core?
Census data and boundary files for various geographic levels are the most commonly used data. However, this is only the tip of the iceberg. The GIA Core maintains a website containing a more detailed listing of available resources. Additional data sets are also available from PRI, although not all of their data sets have a geographic component. PRI maintains a page that lists available data sets by geography, although it is limited to the state and county levels only.
