The Waag Society, together with designer and software engineer Bert Spaan, have put the Netherlands back on the map - the data map. After several months of coding and design, the partnership has managed to account for all 9,866,539 buildings in the country, visualized in varying colors to identify old and new buildings. After a user clicks on a specific block, additional building and city information displays square footages, addresses, populations and programs, among other stats. Users can navigate from Amsterdam to the Hague experiencing hundreds of years of urban development along the way, from the pre-1800s to post-2005 buildings, indicated by the red to blue gradient.
