摘要：There is an increasing demand for 3D city models for many applications and users worldwide. Some of this growth in demand has been caused by the increase in public availability of open geospatial viewers (e.g. Google Earth, Virtual Earth). Although the Historic Peninsula of old Istanbul was added to the UNESCO World Heritage List in 1985, no documentation of this important area has yet been carried out. In 2006 the Istanbul Greater Municipality's Directory of the Protection of Historical Environment initiated the "Historical Peninsula project", which comprises a project area of 1500 ha and approximately 48,000 buildings in crowded and frequently narrow streets. Therefore, BIMTAS, a company of the Greater Municipality of Istanbul, started the documentation and modelling of all buildings in the area of the Historic Peninsula by terrestrial laser scanning (TLS) and aerial imagery in the same year. Although the data acquisition/recording of the project area could be completed within a time slot of 15 months, the 3D mapping and modelling turned out to be a hugely time-consuming challenge. The entire production environment from data acquisition to 3D mapping and modelling of the buildings is described in this paper, whereby the focus is emphasized on the latter. The combination of terrestrial laser scanning data and aerial imagery for deriving new products of 3D city models at different levels of detail is presented
