I currently have a 3D model of the moon. You are able to pick a point on the moon and it takes longitude and latitude coordinates of that point and generates a mesh based on the heightmap. So if you select the inside of a crater, it will create a mesh of that crater and put you in it.
My issue, and focus of the question is that the visual of the north/south poles look correct on the globe, but the data being taken from the heightmap is that of the pre-wrapped image in which the poles are distorted (Shown below).
The look of the north pole on the sphere.
If I chose any of those craters on the surface to generate, I end up with a mesh with stretched out craters, similar to the heightmap. I understand either a calculation must be done, or I need to alter the heightmap in some way I just don't know how.
see below the distorted craters.
