EllipsoidGeodesic Class

A minimum length path conforming to the surface of an ellipsoid and connecting two planetodetic surface points.

This class utilizes the direct and indirect formulations for defining geodesics on an ellipsoid as discussed in "Geodesics on an ellipsoid of revolution.", C. F. Karney, 7 February 2011. The algorithms have been adapted from GeographicLib version 1.44 to optimize performance for the .NET and Java frameworks.

Syntax
`public class EllipsoidGeodesic : EllipsoidSurfaceCurve`

The EllipsoidGeodesic type exposes the following members.

Constructors
NameDescription
EllipsoidGeodesic(Ellipsoid, Cartographic, Cartographic)
Initializes a geodesic on the ellipsoid connecting the two provided planetodetic points.
EllipsoidGeodesic(Ellipsoid, Cartographic, Double, Double)
Initializes a geodesic on the ellipsoid starting at the provided point and which has the indicated heading at that point and ends at a point located at the provided distance from the starting point.

Properties
NameDescription
Ellipsoid
Gets the ellipsoid on which the geodesic lies.
(Overrides EllipsoidSurfaceCurveEllipsoid.)

FinalPoint
Gets the final planetodetic point on the path.
(Overrides EllipsoidSurfaceCurveFinalPoint.)
Gets the heading at the initial point.
InitialPoint
Gets the initial planetodetic point on the path.
(Overrides EllipsoidSurfaceCurveInitialPoint.)
SurfaceDistance
Gets the total distance along the geodesic to the location of the final point.
(Overrides EllipsoidSurfaceCurveSurfaceDistance.)

Methods
NameDescription
ComputeCartographicExtent
Computes the cartographic bounding box which contains the surface curve. This includes looking for the minimum and maximum latitudes which may lie above or below the initial and final points due to oblateness in the Ellipsoid.
(Overrides EllipsoidSurfaceCurveComputeCartographicExtent.)
ComputeHashCode
Computes the hash code for this curve.
(Inherited from EllipsoidSurfaceCurve.)
ComputeIntersection
Computes the nearest intersection (if any) between two EllipsoidSurfaceCurves.
(Inherited from EllipsoidSurfaceCurve.)
Equals(Object)
Indicates whether another object is exactly equal to this instance.
(Inherited from EllipsoidSurfaceCurve.)
Equals(EllipsoidSurfaceCurve)
Indicates whether the current object is equal to another object of the same type.
(Inherited from EllipsoidSurfaceCurve.)
Finalize
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
(Inherited from Object.)
FindClosestPointOnCurve(Cartographic)
Finds the closest point on the curve from the input point.
(Inherited from EllipsoidSurfaceCurve.)
FindClosestPointOnCurve(Cartographic, Double)
Finds the closest point on the curve from the input point.
(Overrides EllipsoidSurfaceCurveFindClosestPointOnCurve(Cartographic, Double).)
GetDiscretePoints
Get a set of points which represent the curve discretely based on a given granularity.
(Inherited from EllipsoidSurfaceCurve.)
GetHashCode
Returns a hash code for this instance, which is suitable for use in hashing algorithms and data structures like a hash table.
(Inherited from EllipsoidSurfaceCurve.)
GetType
Gets the Type of the current instance.
(Inherited from Object.)
Provides the heading at a location on the geodesic.
Provides the heading and rate of change of heading at a location on the geodesic.
InterpolateUsingFraction
Provides the location of a point at the indicated portion along the geodesic.
(Overrides EllipsoidSurfaceCurveInterpolateUsingFraction(Double).)
InterpolateUsingSurfaceDistance
Provides the location of a point at the indicated distance along the geodesic.
(Overrides EllipsoidSurfaceCurveInterpolateUsingSurfaceDistance(Double).)
MemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
SurfaceMotion(Double)
Converts the motion given in terms of motion on the geodesic curve to motion of the surface point.
SurfaceMotion(Double, Double, Double)
Converts the motion given in terms of motion on the geodesic curve to motion of the surface point.
ToString
Returns a string that represents the current object.
(Inherited from Object.)
