Geo-BIM data integration: easier said than done?

The boundary between geo and BIM is getting fuzzy, but working with IFC models from practice shows that converting BIM data in a format useful in GIS and vice versa is still far from straightforward.

Generalising 3D Buildings from LoD2 to LoD1

The increasing popularity of 3D city models in navigation, urban planning, etc.,<br/>necessitates application-specific and geometrically accurate and valid models. The concept of Levels of Detail (LoDs) indicate a model’s scale of adherence to its real-world counterpart. Highly detailed datasets often contain errors or require an exorbitant...

Integrating Scale and Space in 3D City Models

This paper presents the problem of the current separate treatment of levels of detail in city models. We propose a solution, detail the main principles, and present our initial results on the approach. We conclude with work in progress and explain the benefits of our approach.
