The discovery of a particular scanning defect called Bayer moiré, occured while creating image files at Stanford University Library's Map Scanning Lab and prompted a more focused study. The Bayer moiré defect affects the ability of software to lift features from maps digitally.
The Oversized Imaging Lab has recently imaged a 70 x 90 inch rolled Map of Santa Clara County from 1914.
It was shot in 108 tiles and stitched together to create a 600 ppi, 55554 x 42686 or 2.371 gigapixel, 7.11 GB digital surrogate. This is the largest object we have imaged in the Map Scanning Lab thus far - it is an exciting milestone!
