Geographic map model

Hello everyone, I’m a student from Asia working on a project related to building renovation in a mountainous area. However, my Edu account isn’t allowing me to download a realistic mountain model from Sketchup. I’ve tried other sources, but they don’t seem to work. I’ve also posted on local forums, but most people use the Edu version, not the Pro version. I would be very grateful if someone could help me download a realistic mountain model; I’m willing to pay for it.

You know you can create a terrain using the Sandbox extension, right?

Or generate it directly from a heightmap using an extension - Bitmap to mesh?
