----------------------------Original message---------------------------- The 3 arc sec. data is available thru the contact location you received in a message from Allen Brenner. That data base is still available for an ftp lift out. Currently it is not supported by the Nat. Digital Carto. Data Base Office an office within the Nat. Mapping Div. that handles the sales data base. This will change in the near future and there will be an official, supported data base available. The Division is working on policy papers as to the release of such data. John Shanton ESIC-Reston US Geol. Survey
