摘要：Today's car navigation systems have reached a high level of maturity, using huge map databases with a high coverage and up-to-dateness. However, as additional applications gain importance, such as advanced driver information and warning systems, more detailed and accurate information on the true road geometry has to be incorporated into those databases. Properties like height, longitudinal and transversal slope, curvature, and width which are currently not present, have to be acquired and integrated. This article shows how existing databases either from public authorities or from private map providers can be used in combination with aerial laser scan data to derive such properties. Apart from a general discussion of the problem and our approach, first results are presented and discussed
