Building Landscape in UE5 Based On Real World Height Map

Hi all,

I am working on a project where I need to model a real-life location but set it in the context of almost 100 years ago. To do this I have been able to load in the geographic data using Cesium and Google Maps. This is able to give me an accurate reference of the roads and buildings that existed in the past since I can reference the current Google Maps data with historical maps. The problem is that there is no topographical / height map information included in the Google Map data. The area which I am re-creating is also relatively flat despite a few rivers and dikes (yes the location is located in the Netherlands). I have been able to locate and download four detailed height map (.tiff) files and have found the following tutorial which is supposed to help get these tiles into Unreal Engine: https://www.youtube.com/watch?v=9v_7OmgNzIA

However, I am stuck at the point where I need to scale the 10000 x 12500 pixel height map to a dimension that Unreal Engine is capable of handeling (apparently 4033 x 4033).

Is anyone able to assist me in getting the height maps translated into an Unreal Engine landscape? Either via Houdini or another method?

Your help is greatly appreciated.

this is amazing, i was trying to do the same and realized the export resolution is kinda everything here?
even though i can see the relevance of what i imported (from gmaps) its like minecraft quality lol
im sure we’ll figure it out. ill post back if i find out the correct res/ratio/pixel depth?

seen this?

GitHub - iwer/GeotiffLandscape: Unreal Engine Plugin to support geotiff as landscape file format.

i think it only supports up to 5.1

but then theres this i found also

BlenderGIS
GitHub - domlysz/BlenderGIS: Blender addons to make the bridge between Blender and geographic data

The best way to work with DTMs is to use programs meant to work with DTMs, such as GrassGIS or really any GIS program.
Gis being Geographic Information System…

Either eay the OP’s post was from a year ago.
