1. Method of producing road information for a map database comprising:
- acquiring one or more source images from an image sequence obtained by use of a terrestrial based camera mounted on a moving vehicle;
determining a road color sample from pixels associated with an area in the acquired one or more source images representative of a road surface in front of or behind the moving vehicle, including the track line of the moving vehicle;
generating a road surface image from the acquired one or more source images in dependence of the determined road color sample; and
,producing road information in dependence of the generated road surface image and position and orientation data associated with the acquired one or more source images.
