About the Collection
The UW Robinson Map Library partnered with the United States Geological Survey (USGS) in a pilot project aimed at digitizing the entire collection of Wisconsin's topographic maps. This scanning project resulted in a digital archive of over 2,000 map images and metadata for Wisconsin dating back to the early 1900's. Just one year later the scanning project became a nationally-focused effort when USGS committed resources to building a digital U.S. archive of every topographic map ever printed across the country.
The map scales included in the WI collection consist of the oldest 1:62,500 and 1:48,000 maps (or "15 minute" maps) created from the early 1900's until the 1950's, the more detailed 1:24,000 scale maps (or "7.5 minute" maps) that the agency began creating in the early to mid 1950's to present, and both the 1:100,000 and 1;250,000 scale less detailed, regional maps.
