Merging DTM and CAD data for 3D Modeling purposes for Urban Areas

Three dimensional (3D) models became a very important issue in the last few decades due to the increasing demand for a realistic presentation of the real world. A 3D model gives better presentation and facilitates the processes of planning, control and decision making especially in the urban areas. Furthermore modern workstations available on the market allow already to handle and visualize large amounts of data. Since there is need for 3D models and sufficient hardware, the task of the researchers now is to develop technologies for automatic construction of 3D models using different data sources.
