Clik here to view.

All 9,866,539 buildings in the Netherlands were mapped and shaded according to their year of construction in the map above. The map was created by Bert Spaan using TileMill, similar to the Portland and NYC building maps, and completely done with open data (an alternative, easier place to download the data). Give TileMill a try and let us know what you make!
