Supposing you have, in your library, digital data, or digitized maps, broken down into numerous tiles, files, or directories in some electronic format (disk, CDROM, tape, etc.). Would you give serious consideration to processing an Inter-Library-Loan (ILL) type of request from another academic institution, for that data, in whole, or, in part? Would you consider generating a request for digitized data, in whole, or in part, from another academic institution, on behalf of your library clients? As a cartographer and thus a generator and user of digital map data sets, this brings up a number of interesting questions. It has been presumed, up until now, that anyone seeking to create or use a digital map must start the project from scratch (by digitizing/scanning etc original paper map data) in order to create the necessary data set. One does not usually consider a map library as a potential resource for ready-made digital data sets. I should differentiate here between digital data sets and ready made, or "canned" maps. A ready made map is anything available, usually on CD ROM, to illustrate statistical, atlas, physiographic, whatever maps of various countries or states. These maps are finished products, with all the design already incorporated into the presentation, and digitally speaking, are usually locked within their native format, be it a file type that cannot be readily translated, or only available for printing without significant changes, etc. Digital data sets, on the other hand, is map information in a non-cartographic format. It may be edited and processed for clean linework, topology, free of errors etc., but may have had little or no cartographic touches: lettering, line weights and colours, area fills and patterns, symbology, marginalia, and so on. A good example may be a topographic map with only centreline vectors for roads, and an attached feature table describing the different linecodes or layers. For someone seeking to create a map free of the unnecessary data found in a "canned" map, with maximum flexibility over their own design, feature selection and generalization, the digital data set is ideal. Here's the problem: what if there is a desire to copyright that data set? How do you loan out a data set which is perfectly mutable into something else with the assurances that that won't happen? If it is indeed edited and changed enough, is it now considered an original work, and therefore free of copyright? Do you loan it out at all? What good is it if you can't loan it out? I don't have the answers to these questions, but I'd sure like to see some discussion on it. As a cartographer, I'd both love access to free data (saves me a lot of time and effort) and yet I'd hate to realize that something I sweated over creating is now being used freely and profitably without a penny in royalties for my efforts. I do know that the people at Bentley, creators of Microstation, have created a software device which is aimed at preventing unlicensed use of their software: whenever a design file is sent to a plotter, a message is automatically included in the plotfile, and resulting plot, that clearly states the user is not licensed. It can cause considerable embarrassment at conventions, I'm told! Perhaps there are other software solutions out there waiting to be applied. Sean D.
