API Reference > imodeljs-common > Geometry > PositionalVectorTransformProps PositionalVectorTransformProps Interface This interface represents a positional vector (seven parameters) geodetic transformation corresponding to EPSG operation 9606. Beware that the convention relative to rotation direction is different from the Coordinate Frame operation (epsg 9607). Implemented by PositionalVectorTransform Properties Name Type Description delta Readonly<WritableXYAndZ> The frame translation components in meters rotation XyzRotationProps The frame rotation components in arc seconds. scalePPM number Scale in parts per million.
