What is GDF

The development of road database requires the management of continuously growing road databases. Mobile mapping systems can acquire this information, while offering an unbeatable productivity with the combination of navigation and videogrammetry tools. However, the complexity of data georeferencing and the fusion of the results with video sequences require numerous hours of repetitive labor. We propose to introduce the concept of “real time” in the field of mobile mapping. The deterministic exploitation of the data captured during a kinematic survey aims at restricting human intervention in the sophisticated georeferencing process, while authorizing the dissemination of this technique outside well-informed communities. What are the tools and algorithms robust enough to ensure the quality control of the georeferencing of the road objects? We intend to provide these concerns a pertinent answer, while demonstrating the validity of the concept via the automatic acquisition and interpretation of the road geometry.
