The 3D BAG is an up-to-date data set containing 3D building models of the Netherlands. The 3D BAG is open data. It contains 3D models at multiple levels of detail, which are generated by combining two open data sets: the building data from the BAG and the height data from the AHN. The 3D BAG is updated regularly, keeping it up-to-date with the latest openly available building stock and elevation information.
This is the first open 3D building data set that is generated fully automatically and covers a whole country on this level of detail.
For those who missed the description on the webpage, the data that is visualized is called "3D BAG", which we get by combining the "BAG" (buildings) and the "AHN" (point cloud) data sets. The 3D BAG (http://3dbag.bk.tudelft.nl/) is created by the us at the 3D geoinformation group (https://3d.bk.tudelft.nl/).
