Managing Large 3D Urban Databases

TL;DRAbstract

The three dimensional digital data of objects of a city has shown to be a powerful tool for many applications. Namely the planning of wireless networks in cities, the support of decision making processes for urban development projects, the simulation of pollution distribution or the support of civil and military security operations. Today the initial commercial driver for the creation of such data for entire cities is the telecom industry, optimizing their communication networks depending on line-of-sight analysis. In addition to the presentation of the shape of urban objects we have observed the need for an enhanced realism of these data by exploiting the radiometric information of images. Creating such fully three dimensional city scapes has turned to be the key technology for a various number of novel applications, even if the acquisition of missing source data and the maintenance and administration of these huge amount of data needs to be better organized.
