This map was scanned in 25 8.5"x11" sections at 600 dpi using an HP 4600 scanner that was carefully placed on top of the map. Each section was overlapped at least an inch to aid in stitching. The sections were stitched together using Panaview Image Assembler. Color correction and cleanup was done using Adobe Photoshop. Scanning took aproximately 2 hours. Processing took aproximately 18 hours because of the high resolution. The 600 dpi stitched map file is over a gigabyte in compressed form!
