from mobile laser scanning system and cameras in addition to 
airborne laser scanning data and aerial imagery. 
With 3D city models in LODI, LOD2 and LOD3 BIMTAS is 
going to derive new products from laser scanning data and 
aerial imagery, which will fulfil the requirements of many 
applications and users due to the different levels of detail. The 
dominating parts of the production lines for the generation of 
such 3D city models are still manual work, i.e. there is huge 
potential for optimisation and automation of the production to 
complete such projects as the Historic Peninsula in reasonable 
time frames. In the meantime the 3D mapping and modelling of 
landmarks will be continued in order to generate the most 
important landmarks as interactive textured 3D models 
Istanbul is selected as one of European Cultural Capitals in 
2010. Thus, many other projects will come in the near future. 
There is already a request to create the LoDl and LoD2 
products of the area comprising the two sides of the lower part 
of the Bosporus including approximately 15,000 buildings. 
BIMTAS learned many lessons concerning project management 
and tuning of technology to manage the requirements, so that 
the company is well positioned to run similar projects in the 
future.
