Trulia, a real estate search, aggregation, and information site asked Stamen to help demonstrate the extent of their huge catalog of U.S. residential properties. Trulia Hindsight is an animated view onto their database, with an eye towards exposing patterns of expansion and development through home construction dates.

Housing built on an artificial lake: Discovery Bay

Hindsight features several notable locations around the U.S., from the suburban fields of Plano, Texas to the oceanfront apartments of Miami. The Trulia Hindsight blog features these and other spots, and welcomes input from readers with interesting patterns to share. Development on the project was punctuated by real estate exploration trips, as we zoomed around the country exploring construction histories of cities, towns, suburbs, and neighborhoods.

Vast records of urban development are a joy to get lost in.

The project features some of our most information-dense work to-date, and helps to make it most useful and shareable for visitors by supporting continuous permanent links to map views. Hindsight is built atop the ActionScript map tiling engine Modest Maps, co-developed by Stamen. We were privileged to have worked with designer Geraldine Sarmiento on this project.
