It's Stereographic, the AE map ice wall is bunk.

We live in a virtual realm, and the map (coordinate system) is stereographic. The plane of Earth is fixed & immovable. There is no curvature, no gravity, no dome, and no ice wall...

Earth has 4 corners and 2 polar rotations. All of the luminaries in the sky are being rendered locally to each individual observer's circle of sight (eyes, cameras, etc.)...
