AHN3 Height Model Released on PDOK
The latest AHN3 height model is released via the PDOK portal of the Dutch government. This is the third generation AHN height model of the Netherlands that can be downloaded for free from their website, and be used for the reproduction of data.
The AHN3 data can be downloaded as GeoTIFF tiles, the entire country is not covered yet, but it soon will be. The GeoTIFF files can be opened in Fledermaus to build 3D models. PDOK offers the data as raw 0.5 to 5 meter grids, these contain buildings, trees, other objects, etc, and ground level 0.5 to 5 meter grids that do not contain buildings, trees etc. It is also possible to download LAZ point clouds.

Besides the AHN3 model there is a vast database of all kinds of other GIS products that can be downloaded and used in the QPS range of products, such as topographic raster charts of different scales and infrastructure information as vector data.
It is very useful to add the AHN3 data to Qimera and combine it with multibeam data that needs to be processed. The AHN3 model can then be used as reference, this gives a good overview of the surrounding area, and can clarify certain features on the seabed.
Luckily our QPS office location in Zeist can be downloaded from PDOK, and we are happy to inform you that we are more than 8 meters above sea level, not below sea level like most of the country.
The Dutch office is situated in the town of Zeist, close to the city of Utrecht, right next to the A28 motorway exit surrounded with nice forest. Attractions in the area include a beautiful old castle from the 17th century and a pyramid with a height of 36 meters, built by Napoleon's soldiers to celebrate the victory in Egypt.
Both landmarks are very well visible in the AHN3 height model data.
