About this person
It is housed at the university's Green Library in the David Rumsey Map Center, which opened in 2016. He began making his collection publicly available in 1997, and is recognized for his contributions to cartographic research and web information systems as an innovator in digitization, archiving, public engagement and data visualization. In 2002, Wired magazine commented, "Rumsey's online map collection introduced a revolutionary, accessible way for people to experience old maps by comparing them to modern geospatial data." Since then his work has integrated map-exploration tools including 2-D and 3-D overlays and virtual and augmented reality equipment.
