A method and system for determining a geographical location and orientation of a vehicle travelling through a road network is disclosed. The method comprises obtaining, from one or more cameras associated with the vehicle travelling through the road network, a sequence of images reflecting the environment of the road network on which the vehicle is travelling, wherein each of the images has an associated camera location at which the image was recorded. A local map representation representing an area of the road network on which the vehicle is travelling is then generated using at least some ofthe obtained images and the associated camera locations. The generated local map representation is compared with a section of a reference map, the reference map section covering the area of the roadnetwork on which the vehicle is travelling, and the geographical location and orientation of the vehicle within the road network is determined based on the comparison.
