The data comes from the official BAG register (<em>Basisregistratie Adressen en Gebouwen<\/em>), maintained by the Dutch Cadastre.<\/p>\n\n\n\n<p>The map perfectly illustrates the history of urbanization in the country: dense historic city centers, post-war housing estates, modern suburbs, and the dynamic development of recent years. Colors correspond to the year of construction \u2014 from the oldest (dark shades) to the newest (vibrant colors, including buildings constructed after 2015). We especially recommend zooming in on Amsterdam, Rotterdam, or Utrecht \u2014 the contrast between old and new architecture is striking.<\/p>\n\n\n\n<p>Spaan\u2019s project is not just a beautiful visualization \u2014 it is a powerful tool for spatial analysis, urban planning, and understanding how the Netherlands has changed over the centuries. \u201cPeople loved that map back in 2013. Ever since then, I\u2019ve wanted to make a better version,\u201d the author admits.<\/p>\n\n\n\n<p>Link: <a href=\"https:\/\/bertspaan.nl\/buildings\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">https:\/\/bertspaan.nl\/buildings\/<\/a><\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Dutch programmer and data visualization expert Bert Spaan has just released an impressive update to his iconic project from 12.5 years ago.
