Tabletop map landscape level

Hi there,
Can someone help with directions to resources that can help me achieve something like this? Ares VR with Virtual Sand Table using Seattle Terrain - YouTube
I can work with GIS data, import it in Unreal, create environments based on real world data and know my way around blueprints. But I do not have any idea how can I do that. I think is something related to scale but probably I am totally wrong.
I want to create an environment and put it onto a table and be able to walk around it.
Thank you very much!

please excuse my bad English : :smiley:

When creating the landscape, scale the xyz down (from its base 100) to something small. that way the landscape tri count will stay the same but scale will be adjusted. then 3d model a table and place the landscape on it :wink:

Thank you! But this way I will lose the lat long coordinates right? I want to scale it but not lose the coordinates.
