Defining 3D GIS city models in different levels of detail (LoD) is often needed to browse and handle large models more efficiently. In this paper, a methodology framework for automatic transformation of different LoDs in CityGML is presented and illustrated. A new exterior shell extraction algorithm was developed from the Ray Tracing algorithm for classifying building surfaces as interior or exterior. A transformation framework among each LoD was developed based on the new exterior shell extraction algorithm. The transformation framework also includes an additional LoD called LoD3.5 that the authors proposed in this paper. The new LoD can satisfy the needs of applications which require information about interior rooms while maintaining a small data storage. The results show that the new exterior shell extraction algorithm can help achieve an automatic derivation of LoDs in CityGML.

[Vedettes matières IGN] GéovisualisationRésumé : (Auteur) Due to recent technological advances in 3D geographic information system (GIS); These 3D visualization technologies have been widely used in urban planning decisions, including: where to build, how to plan for natural disasters, the use of finite resources, how to incorporate sustainable practices, designing for growing populations and other engineering applications. In this study 3D GIS visualization technology is applied to Karsiyaka (Izmir) settlement area to show its applicability for the land use planning, construction and management. This study is carried out in four different stages: In the first stage; 1:25000 scale topographic maps and 1:1000 scale geological maps are digitised in GIS environment and their attribute tables are stored in the GIS databases. In the second stage; sub-surface of the study area was visualized using 3D technologies. This visualisation process is used to assist decision-making for land use planning. In the third stage; and useful soil class zonation maps are performed to be used in further studies. At last stage; after research at this site, the construction applications of Karsiyaka have been multiplied.

[Termes IGN] SIG 3DRésumé : (Auteur) This paper discusses a new approach in object extraction from aerial images with association of point cloud data. The extracted objects are captured in a 3D space for reconstructing a 3D model. The process includes three steps. In the first step the targeted objects are extracted from point cloud data and captured in a 3D space. The objects include buildings, trees, roads and background or terrain. In the second step the extracted objects are registered to the aerial image for assisting the object detection. Finally, the extracted objects from the aerial image are registered on the original 3D model for conversion to the point cloud data and then are captured in a 3D space for reconstructing a new 3D model. The final 3D model is flexible and editable. The objects can be edited, audited, and manipulated without affecting another objects or ruin the 3D model. Also, more data can be integrated in the 3D model improve its quality. The aspects of this project are: to reconstruct the final 3D model, and then each object can be interactively updated or modified without affecting the whole 3D model, and to provide a database for other users such as 3D GIS, city management and planning, Disaster Management System (DBS), and Smart City application.
