Creating a 3D model is a complex process that consists of different techniques and technologies from ALS to photogrammetry, 3D modelling An increasing number of applications and systems incorporate virtual 3D models such as essential system components such as for urban planning and redevelopment , facility management , logistics , security , telecommunication , disaster management , location-based services .Consequently , a large number of potential users and usages require an efficient and effective access to and tools for 3D models and their contents The challenge will now be how to combine, manage all the data and use them effectively.
