Years ago I bought an interactive map & guide to Anhk-Morpork, very impressive, with both a map and an aerial view up to the last detail. The app never updated and soon become incompatible, big loss. I dismantled it and recovered the 23766 tiles of 256x256 pixels each that composed the two images. I've been slowly rebuilding the aerial one into a giant 24064 x 16896 px image. Already 3/4 done. I intend to print a great poster for my studio. Detail is insane.
