Poster presented at the LCDP Luminary Class, June 2012. In 2009, Stanford began an effort to scan its maps. Scanning large format items such as maps create a multitude of challenges. One of these challenges is to capture the map with specifications that meet all known repurposing needs. A prominent repurposing need is to ensure that the map can be consumed in a Geographic Information System (GIS). A team of Stanford University Library staff consisting of Patricia Carbajales, G. Salim Mohammed, Matt Pearson and Renzo Sanchez-Silva (noted here in alpha order) along with student assistants, conducted a detailed study of a Russian Topographic scanned map where details were visually inspected and checked for scanning errors.
