Here is my question: I am looking for a database that shows the relationship between USGS 24k Quads and their counties. For example, USGS 24k Princeton Quad is located in Mercer County, New Jersey. Angela Lee's answer: A index map showing the outlines of the 1:24k quads is included with ArcUSA. (also includes indices for 1:100k and 1:250k quads). Rich Green's answer: Try this site: http://www.gisdatadepot.com/Or, there is a free searchable catalog on CD for USGS products available from:http://www.usgsquads.com I used the ArcUSA CD--index map showing the outlines of the 1:24K quads and county outlines data--then I made the spatial join function called UNION and created a database which shows the relationship between USGS 24kQuad and their counties.
