Summary

Modelling the real world is not a trivial task. Most of the current models are either large area models with few details, or small city-or street-level models with lots of details. The models are mostly produced for one type of use only, although they could have a wide variety of uses: This could be achieved by supporting multiple levels of detail, different visualizations and different platforms.

This paper describes a dual way of producing models that meet the demands mentioned above. By combining two specific modelling approaches it is possible to create cost-efficient and object-based virtual models.
