EllipsoidGrazingAltitudeLocation Method (Cartographic, UnitCartesian)

Provides the point on the line segment from the provided location 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 location. This means that possibly closer points in the opposite direction are not reported.

Syntax
public Cartographic GrazingAltitudeLocation(
	Cartographic location,
	UnitCartesian direction
)

Parameters

location
Type: AGI.Foundation.CoordinatesCartographic
The planetodetic position exterior to the ellipsoid.
direction
Type: AGI.Foundation.CoordinatesUnitCartesian
The reference direction.

Return Value

Type: Cartographic
The nearest planetodetic point on the line segment.
Remarks
If the line segment passes through the ellipsoid then the height of the returned Cartographic will be a negative value representing the maximum depth required to reach the surface.
