Embodiments of the present invention provide a method of generating a shaped line in a geographic data information system, comprising selecting a first shaped line (100) in the geographic data information system, determining (205) a clothoid spline (300) representation of the shaped line, determining (210) a location of a first shape point corresponding to the clothoid spline (300) and determining (235) a location of a second shape point corresponding to the clothoid spline (300), wherein the location of the second shape point is determined (510) to be a maximum chord length from the first shape point within a predetermined tolerance. |
