Blender Hoogtedata Addon (Dutch Height Data in Blender)

I’ve been experimenting with a way to automatically get high quality 3D information of the Netherlands into Blender.

You can choose from 3 different types of data:
A raw heightmap (with buildings and vegetation), a heightmap of just the terrain, and 3D buildings.
(AHN3 DSM, AHN3 DTM, and 3D BAG)

This plugin depends in BlenderGIS


DOWNLOAD FROM GITLAB

This is the first public release of the plugin, so please let me know if and when it breaks.

How to use:

A basic walk-through, as well as more detailed instructions, can be found here:
https://gitlab.com/thomaskole/blender-hoogtedata-addon/-/wikis/home

In short:

Use Blender GIS to get a basemap:

Use this addon to get a heightmap:

Get 3D buildings:

Project your original basemap:

All of these things can be done with just a few clicks.

Have fun!

I’ve changed the way temporary images are stored. The previous way was causing issues for Windows users, this should fix it.

looks great, is blender 3.x supported?

Yep, it should work

Thank you for this interesting add-on! To my regret I get the following message:

As you see in the background there is basemap, or I am doing something wrong. Please can you have a look at it.

This is a bit impractical, but you have to exit the basemap fetch mode with [escape] rather than [e]. This creates an Empty with an image, rather than a geometry plane. Sorry of the confusion!

Thank you for this great add-on. It works beautiful now!

Small addition to the add-on:

You can now get general coordinate info under Hoogtedata > Utils > Get Coordinate Info

This way you can easily copy and paste into different applications.

Wow, fantastic!

BYW, Is it available only in the Dutch area?

Yep, this is using a public Dutch dataset, which only covers the Netherlands

Hi, with a fresh Blender 3.3 I can’t enable the add-on:

Hey, looking awesome!
Unfortunately It does not show me the AHN heights, any ideas? (also for me only the ‘‘blenderGIS-master’’ zip worked, the rest same as above

Weird, I can install it no problem.
Did you first try to install Blender GIS, and then the Hoogtedata addon?
What blender version are you running?
And are they enabled like so?

Ophalen van de BAG 3d gebouwen werkt van de een op de andere dag niet meer? Is er iets vanuit de API veranderd waardoor de addon niet meer werkt?

Ik krijg sinds kort een HTTP404 error wanneer ik AHN data (0.5 en 5.0m) wil ophalen. Heeft iemand hetzelfde probleem of is hier een fix voor bekend?

Het lijkt er op dat de URL verandert is. Ik fix dit a.s.a.p.

It should work again, the URL did indeed change.

Just download it again from gitlab and replace.
