1. A method for creating geometry for an advanced driver assistance system application, comprising:

  • creating link chains from a plurality of segments that represent a portion of a road network;

    creating 2D B-splines from the link chains;

    creating, by a processor, 3D B-splines from the link chains, the 2D B-splines, and height data; and

    storing data representing the 2D B-splines and the 3D B-splines in a database, wherein at least one advanced driver assistance system application uses road geometry information generated from the stored 2D B-spline and the 3D B-spline data to control vehicle operation.
