Im struggling with a problem

im struggling with putting a high resolution image on a terrain mesh i downloaded from my towns geo data website. i explained my problem in more detail in a reddit post. would highly appreciate if youd look at it! Thank you!

any reason you cant just put that image on the mesh you have (project from view) and then adjust the UVs to line the image up with the mesh?

The terrain as is would not be suitable for a game mesh…and making a heightmap from the image ( is iffy ) … But you could try Materialize to make the Normal and heightmaps… personally, I would take a flat plane subdivided and with a subdivision modifier and shrinkwrap it to the mesh you have already that would give you a better mesh to work with…you could then bake a Normal map from the Higher-res to this new one, and get going from there…

You might want to look at this, and see if this would be a better option for you…
