Architectural History Viewer

University of Wisconsin-Madison's Garrett Dash Nelson has developed a wonderful architectural history timeline/map interface. He created the map by using some 62,400 Madison property records that he geolocated in 2013. Structural identifications include stylistic categories and building typologies.

Access the map here.
