Laser scanning is a fast and precise technique for resampling the earth into irregular pattern. The large number of laser points hitting planar facades in urban areas makes it possible to extract objects (buildings, vegetation, etc.) in the areas. This paper has presented a new approach to extract buildings through analyzing characteristic of contours generated from LIDAR point data, which has been proved to be a robust and reliable method.
