----------------------------Original message---------------------------- There's a new proiduct available from the U.S. Geological Survey using the NAPP 40,000 1/4 quad centered photogarphy. This is the series of AP called the Digital Orthophoto Quads. There currently are only 37 CD's available at this time. Each CD covers a complete county within a State. The series is very random across the country now. The intent is to cover the whole US. If you will give to me your fax # I'll get to you the current list of available counties.
