geodesic parameters

[¦jē·ə¦des·ik pə′ram·əd·ərz] (mathematics) Coordinates u and v of a surface such that the curves obtained by setting u equal to various constants form a family of geodesic parallels, while the curves obtained by setting v equal to various constants form the corresponding orthogonal family, of length u2-u1 between the points (u1, v) and (u2, v).
