Methods

Name Description
constructor(props: EcefLocationProps): EcefLocation Construct a new EcefLocation.  
getTransform(): Transform Get the transform from iModel Spatial coordinates to ECEF from this EcefLocation  
isAlmostEqual(other: EcefLocation): boolean Return true if this location is equivalent to another location within a small tolerance.  
toJSON(): EcefLocationProps    
createFromCartographicOrigin(origin: Cartographic, point?: Point3d, angle?: Angle): EcefLocation Static Construct ECEF Location from cartographic origin with optional known point and angle.  
createFromTransform(transform: Transform): EcefLocation Static Construct ECEF Location from transform with optional position on the earth used to establish the ECEF origin and orientation.  

Properties

Name Type Description
cartographicOrigin Readonly undefined | Cartographic Optional position on the earth used to establish the ECEF origin and orientation.  
earthCenter Accessor ReadOnly Point3d Get the location center of the earth in the iModel coordinate system.  
orientation Readonly YawPitchRollAngles The orientation of the ECEF transform  
origin Readonly Point3d The origin of the ECEF transform.  
xVector Readonly undefined | Vector3d Optional X column vector used with EcefLocation.yVector to calculate potentially non-rigid transform if a projection is present.  
yVector Readonly undefined | Vector3d Optional Y column vector used with EcefLocation.xVector to calculate potentially non-rigid transform if a projection is present.
