and at the poles. It's latitude that gets compressed at the poles.

Going north means changing latitude to approach 90 degrees north latitude at the pole. Those degrees of latitude are evenly spaced in distance (s=rtheta, if theta is angle north of the equator).

Going east means changing longitude, rising from -180 degrees to 180 and then resetting. Those degrees of longitude correspond to less and less distance at the poles (s=rcos(theta)*phi, if theta is angle north of the equator and phi is angle around the axis).
