----------------------------Original message---------------------------- The Federal Geographic Data Committee's publication, "Manual of Federal Geographic Data Products," is a compilation of Federally produced maps and related spatial data. It was produced for the EPA to "provide a means of satisfying the EPA's internal need for a comprehensive, standardized description of Federal geographic data products." It is available through the U.S. Geological Survey (USGS): Federal Geographical Data Committee Secretariat USGS 590 National Center Reston, VA 22092 (703) 648-4533 fax: (703) 648-5755 The publication is not specific to GIS, but it is very interesting.
