In this paper we propose an automatic updating system for urban vector maps that is able to detect changes between the old dataset (consisting of both vector and raster maps) and the present time situation represented in a raster map. In order to automatically detect as much changes as possible and to extract vector data for new buildings we present a system composed of three main parts: the first part detects changes between the input vector map and the new raster map (based on edge matching), the second part locates new objects (based on color segmentation), and the third part extracts new objects boundaries to be used for updating the vector map (based on edge detection, color segmentation and adaptive edge linking). Experiments on real datasets illustrate the approach.
