Methods

Name Description
clone(result?: Cartographic): Cartographic Duplicates a Cartographic.  
equals(right: CartographicProps): boolean Return true if this Cartographic is the same as right  
equalsEpsilon(right: CartographicProps, epsilon: number): boolean Compares this Cartographic component-wise and returns true if they are within the provided epsilon,  
freeze(): Readonly<Cartographic> Freeze this Cartographic  
toEcef(result?: Point3d): Point3d Return an ECEF point from a Cartographic point  
toJSON(): CartographicProps Create a JSON representation of a Cartographic object.  
toString(): string Create a string representing this cartographic in the format '(longitude, latitude, height)'.  
createZero(): Cartographic Static Create a Cartographic object with longitude, latitude, and height of zero.  
fromAngles(args: { height?: number, latitude: Angle, longitude: Angle }, result?: Cartographic): Cartographic Static Create a new Cartographic from longitude and latitude in Angles.  
fromDegrees(args: { height?: number, latitude: number, longitude: number }, result?: Cartographic): Cartographic Static Create a new Cartographic from longitude and latitude specified in degrees.  
fromEcef(cartesian: Point3d, result?: Cartographic): undefined | Cartographic Static Creates a new Cartographic from an ECEF position.  
fromRadians(args: { height?: number, latitude: number, longitude: number }, result?: Cartographic): Cartographic Static Create a new Cartographic from longitude and latitude specified in radians.  
geocentricLatitudeFromGeodeticLatitude(geodeticLatitude: number): number Static return the geocentric latitude angle for the input geodetic latitude angle (both in radians).  
parametricLatitudeFromGeodeticLatitude(geodeticLatitude: number): number Static return the parametric latitude angle for the input geodetic latitude angle (both in radians).  
scalePointToGeodeticSurface(point: Point3d, result?: Point3d): undefined | Point3d Static Scale point to geodetic surface
