1. A method for creating geometry for a driver assistance 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 3D B-splines from the link chains, the 2D splines, and height data; and
storing data representing the 2D B-splines and the 3D B-splines in a database, wherein at least one driver assistance application uses road geometry information generated from the stored 2D B-spline and the 3D B-spline data.

Abstract
A method and system for creating geometry for ADAS are described. Link chains, which are a sequence of segments, are created. The link chains are used to create 2D splines. The link chains, the 2D splines, and height data are used to create 3D splines. The 3D splines and possibly the 2D splines are converted to Bezier curves, which can be used to create a 2D polyline. ADAS applications can use the Bezier curves and the 2D polylines to provide ADAS functions.
