EllipsoidGrazingAltitudeLocation Method (Cartesian, UnitCartesian)
Provides the point on the line segment from the provided position and along
the indicated direction which is nearest to the ellipsoid.
The line segment is considered to be infinite in length but starting at
the provided position.
This means that possibly closer points in the opposite direction are not reported.

- Type: AGI.Foundation.CoordinatesCartesian
The position exterior to the ellipsoid.
- Type: AGI.Foundation.CoordinatesUnitCartesian
The reference direction.
The nearest planetodetic point on the line segment.
If the line segment passes through the ellipsoid then the height of the returned Cartographic
a negative value representing the maximum depth required to reach the surface.
