1. Method of generating a geodetic reference database product, the method comprising:

  • acquiring mobile mapping data captured by means of digital cameras, range sensors and position determination means mounted to a vehicle driving across the earth surface, the mobile mapping data comprising simultaneously captured image data, range data and associated position data in a geographic coordinate system;

    determining linear stationary earth surface features from the mobile mapping data by processing the image data, range data and associated position data;

    generating 3D-models for the linear stationary earth surface features in the geographic coordinate system from the image data, range data and associated position data; and

    storing the 3D-models in a database to obtain the geodetic reference database product;

    the method further comprising;

    generating orthorectified images for the 3D-models by combining image data and range data,determining elevation information in the geographic coordinate system for pixels of the orthorectified images;

    linking the orthorectified images and the elevation information to obtain 3D-orthorectified images; and

    storing the 3D-orthorectified images and linking the images to respective 3D-models in the geodetic database product.
