----------------------------Original message---------------------------- I have heard about some software, which I believe is called EDRISI. Does anyone use this to display DOQ's or other digital data from the U.S.G.S.? We are a small, undergraduate departmental library and also are a U.S.G.S. depository. Faculty members are interested in obtaining software that will allow them to access the digital data we receive, and work on a very basic level. Does EDRISI sound like something we would find useful?? Do those of you with partial GIS systems recommend something else? Thanks, in advance, for your comments!
