Top and bottom sections of the map were scanned at the Cleveland Digital Public Library using the I2S SupraScan Quartz A0

Middle section scanned using the HP 4600 scanner
I2S SupraScan HP 4600

The map is aproximately 100" x 70". The maximum width that can be scanned at one time on the I2S is 34". The top and bottom 34 x 100 inches were each scanned in 3 sections and stitched together. The middle 2+ inches of the map could not be scanned, and were initially photographed in multiple sections using a hand held camera. Aligning these middle sections from photographs proved difficult. The middle was then scanned in 11 overlapping sections (8.5 x 11" @) using a discontinued HP 4600 scanner that sits on top of the map. Because the map top and bottom sections were not completely flat when scanned, there were some minor alignment issues between the 3 scan paths (top, middle and bottom). These scan paths were aligned using Photoshop's Puppet Warp and Layer Masking features. The color differences between the two scanners were not adjusted so it is clear where they were joined.
