geodesic polar coordinates

[¦jē·ə¦des·ik ¦pōl·ər kō′ȯrd·ə·nəts]
(mathematics)
Coordinates u and v of a surface such that the curves obtained by setting u equal to various constants are geodesic circles with a common center P and geodesic radius u, and the curves obtained by setting v equal to various constants are geodesics passing through P such that v0 is the angle between the tangents at P to the lines v = 0 and v = v0.
