----------------------------Original message---------------------------- I was asked to be a little more specific about what we're looking for. Every year students are given an assignment wherein they have an aerial map (7.5 minute series) and have to identify the location based on a close analysis of the terrain, infrastructural elements, etc. Typically, they struggle mightily. So, it occurred to us as a Reference Dept. that there might be a CD-ROM product that would simplify the identification of a given map. That's as far as we've gotten. Of course, the CD would change the nature of the assignment completely, and we haven't consulted with the professor(s) in question to determine whether making such a resource available to the students would further the course's instructional objectives .... At any rate, that's where we're at. Cheers! CAB VINTON Frostburg State Univ. [log in to unmask]
