The objective is to study the suitability of laser data to generate a DSM for road planning and design in the Netherlands. The conclusion is that high-density laser measurements allow the reconstruction of the terrain relief with the required accuracy. Nonetheless, they do not allow the extraction of all the information required, particulary semantic information. Thus, the combination of laser data with existing geographic information is a prerequisite. This process of combining laser data with existing geographic information is not trivial. The rate of success depends much on the quality of the individual data sets and the method used to combine them. This problem appears in a much broader context, that of spatial data fusion, and should be object of future research.
