----------------------------Original message---------------------------- Before I dip into my meager pool of dissertation research dollars I thought I might hazard a query to the list. I meed to obtain 1:20,000 USGS DLG's and DEM's for the following 7 1/2" quads in Puerto Rico: Aguas Buenas, Caguas, Comerio, El Junque, Gurabo, Humacao, Juncos, Patillas, and Yabucoa. All the above quads have corresponding DLG's and some have DEM's. I checked spectrum.xerox.com and found a DLG (hypsography) for El Junque, but no others. Might anybody have these files and be willing to make them available? Thank you. Robert Swett Department of Geography University of Florida Gainesville, FL. 32611 [log in to unmask] PH: 904-392-6233
