API Reference > imodeljs-common > Geometry > GeodeticTransformProps GeodeticTransformProps Interface This interface represents a geodetic transformation that enables transforming longitude/latitude coordinates from one datum to another. Implemented by GeodeticTransform Properties Name Type Description geocentric undefined | GeocentricTransformProps When method is Geocentric this property contains the geocentric parameters gridFile undefined | GridFileTransformProps When method is GridFiles this property contains the grid files parameters method GeodeticTransformMethod The method used by the geodetic transform positionalVector undefined | PositionalVectorTransformProps When method is PositionalVector this property contains the positional vector parameters sourceEllipsoid undefined | GeodeticEllipsoidProps The complete definition of the source geodetic ellipsoid referred to by ellipsoidId. targetEllipsoid undefined | GeodeticEllipsoidProps The complete definition of the target geodetic ellipsoid referred to by ellipsoidId.
