Summary
| Description |
English:
Ellipsoidal coordinates as used in geodesy. For a point P not on the reference ellipsoid (semi-axes OA and OB) construct an auxiliary ellipsoid which is confocal (same foci F, F') with the reference ellipsoid: the necessary condition is that the product
ae
of semi-major axis and eccentricity is the same for both ellipsoids. Let
u
be the semi-minor (OD) of the auxiliary ellipsoid. Further let β be the reduced latitude of P on the auxiliary ellipsoid. The set(
u
,β,λ) define the ellipsoid coordinates.
