Hi TripleThree, thanks for your comments on the maps in Trams in Adelaide.

• Scanned in various street maps and google earth satellite images.
• Combined them into a master back image. Note that this image is used just to get the scale and distances correct, and to locate major roads.
• Used adobe illustrator selectively draw a map, using the scanned image as a backdrop.
  • Information on the maps comes from different sources to the scanned ones, in the case of Image:Adelaide trammap 1950s.png from a wall chart map at a tram museum.
• Delete the master image and save map as an SVG only with no copyright information included.

I'm told that the free software Inkscape is capable of being used in place of Illustrator for this. My thinking on the copyright is that the creator of a map (or satellite image) has clear copyright on their work, but that information can be derived from this work without infringing. - Peripitus (Talk) 03:59, 5 May 2008 (UTC)
