Navigation using GPS is a common strategy which cannot provide the desired accuracy in forests. In the forestry of North Rhine- Westphalia (Germany) algorithms are developed to delineate single trees from remote sensing data. These generated tree maps can be used to create a virtual testbed. Different kinds of sensor data can be merged to form a "visual GPS" system which improves accuracy for the navigation of autonomous vehicles in the forest. Algorithms were developed, which provide localization results accurate enough to allow navigation to a single tree.
