Azavea Commons

Through our research projects, pro bono work and other activities, we sometimes create something we feel has potential value for others, such as a new dataset, map, tool or even complete software.  We are pleased to make these available to the wider community here, in Azavea Commons.

Sesquicentennial Map

sesqui_map.png
Held in Philadelphia in 1926, the Sesquicentennial International Exposition celebrated the 150th anniversary of the signing of the Declaration of Independence. A collection of Sesquicentennial photos is now available on PhillyHistory.org. Since the location of the Exposition has changed a bit since 1926, we combined a current street map with a map of the Sesquicentennial grounds to create this two-layer map that makes it easy to see exactly where the festivities occurred.
