Original maps were photographed using a Mamiya R267 camera on 120 film and scanned at 4,000 dpi as TIFF files on a Nikon Super Cool Scan 8000. The TIFF files were converted into the MrSID format at a compression ratio of 12 to 1 using LizardTech's Geospatial Encoder 1.4 software. These MrSid files were then uploaded into the CONTENTdm database at the Washington State University Libraries.
