Yes, scale and recenter everything to the origin (0, 0, 0) then, depending on your software, make sure you reset/apply those transformations (in 3ds max it is/was “Reset Xform” and in Blender it’s “Apply > All Transforms”).
But it depends on your use case. If you need the user to get really close, like walking around on the surface, then you will need some kind of level of detail, terrain tiling system.
