API Reference > imodeljs-common > Geometry > Cartographic Cartographic Class A position on the earth defined by longitude, latitude, and height above the WGS84 ellipsoid. Implements LatLongAndHeight Methods Name Description constructor(longitude: number = 0, latitude: number = 0, height: number = 0): Cartographic clone(result?: Cartographic): Cartographic Duplicates a Cartographic. equals(right: LatLongAndHeight): boolean Return true if this Cartographic is the same as right equalsEpsilon(right: LatLongAndHeight, 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(): LatLongAndHeight toString(): string Create a string representing this cartographic in the format '(longitude, latitude, height)'. fromAngles(longitude: Angle, latitude: Angle, height: number, result?: Cartographic): Cartographic Static Create a new Cartographic from longitude and latitude in Angles. fromDegrees(longitude: number, latitude: number, height: 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(longitude: number, latitude: number, height: number = 0, 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 Properties Name Type Description height number latitude number latitudeDegrees Accessor ReadOnly number latitude, in degrees longitude number longitudeDegrees Accessor ReadOnly number longitude, in degrees Defined in core/common/src/geometry/Cartographic.ts Line 23 Last Updated: 29 November, 2022
