Abstract:
1. A method of generating, by a computer implemented system comprising one or more processors, a geodetic reference database product, the method comprising: acquiring, by the one or more processors, 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, by the one or more processors, linear stationary earth surface features from the mobile mapping data by processing the image data, range data and associated position data; generating, by the one or more processors, 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, by the one or more processors, the 3D-models in a database to obtain the geodetic reference database product; the method further comprising: generating, by the one or more processors, orthorectified images for the 3D-models by combining image data and range data, determining, by the one or more processors, elevation information in the geographic coordinate system for pixels of the orthorectified images; linking, by the one or more processors, the orthorectified images and the elevation information to obtain 3D-orthorectified images; and storing, by the one or more processors, the 3D-orthorectified images and linking the images to respective 3D-models in the geodetic database product.
