Public Methods

Method

Description

CCGridDirect

Given a reference point and a CCG string, this method calculates the location of the point described by the CCG string

CCGridInverse

Given a reference point and a contact point, this method calculates the CCG string that describes the location of the contact point relative to the reference point

ComputeDirect

Given a point, an azimuth, and a distance, this method computes a Great Circle that passes through the specified point at the specified azimuth and returns the point on the Great Circle that is the specified distance from the input point

ComputeInverse

Given two points, this method computes a Great Circle that passes through both points and returns the azimuth at which the Great Circle intersects each point as well as the distance between the points on the Great Circle

ComputeOrthometricScaleAtLatitude

Computes the height scale at a specific latitude and ellipsoid height

ComputeRadiusAtLatitude

Produces the radius of the IEllipsoid3 at the specified latitude

DeepCopy

Produces a deep-copy of an IEllipsoid3 instance

HasIdentifiersIn

Indicates if this object has an identifier that is also present in the specified object

PolygonArea

Calculates the area of a polygon on this IEllipsoid3

RhumbDirect

Given a point, an azimuth, and a distance, this method computes a Rhumb Line and finds the point that is the specified distance away from the input point

RhumbInverse

Given two points, this method computes a Rhumb Line between the points and returns the distance between the points on the line and the azimuth of the line.

ValueEquals

Compares the value of two instances of IEllipsoid3
