Buildings in urban areas take large percentage in city structures, of which 3-dimensional information is needed for variety of applications such as facility management system, road design, building land development or town planning. Recently, many studies on the 3-dimensional modeling of buildings have been done, which are by the help of not only the development of analysis algorithm but also the spread of aerial imagery, high-resolution satellite imagery, LiDAR data and digital photogrammetry system. Among the data, LiDAR data is being regarded as one of the most useful data because it allows acquisition of the precise DSM. However, using only the LiDAR data to acquire 3-dimensional modeling of buildings has some problems because it needs manual linearization and subjective reconstruction. Thus, in this paper, digital maps of 1:5,000 scale and LiDAR data are used together to extract the 3-dimensional model. The 3-dimensional modeling of buildings are very well done and the user's manual works are needed not so much. From the accuracy test results using aerial imagery and digitizing, the 3-dimensional modeling of buildings in urban areas and renewal of digital map are feasible by automatic manner to some extent.
