However I think any holders of original vector data will be loathe to send out their maps because they are essentially giving up their copyright to a valuable product. Someone, or many someones, worked hard and long to create, edit and clean a vector map database, which will ultimately be used in GIS uses, or output to produce hard copy paper maps for retail sale. Those people have to make a living and they are going to want money for their work. Now copyright laws in Canada are somewhat vague on maps and electronic media, but one standard seems to be true: if you do enough editing or design work of your own, so that the new product is substantially different from the old one, you now have copyright over this product. Considering how easy it is to take a set of vectors and push a few around, assign new colours and lineweights, add some new type and marginalia, this "new product" can be arrived at quite quickly and inexpensively. And meanwhile, those people who went to considerable expense collecting data, purchasing aerial photographs, satellite images, government base maps, statistical studies, field surveys, etc., have had their work hijacked by someone else who just puts a different face on it. I think the true legal nature of this is yet to be resolved, but the danger exists...send out your map data, and you've lost your potential market return to someone else. This is also why some of the currently available maps (Magellan maps on Compuserve, or Digital Chart of the World) tend to be simple, relatively small scale maps that are already quite well diffused throughout society in paper form. It also explains why government sources, when they are offering to sell digital maps, charge steep fees for them. Hope this puts some perspective into your query! Yours, Sean D.
