Automatic Generation of 3D Building Models for Sustainable Development

3D city models are important in urban planning for sustainable development. Urban planners draw maps for efficient land use and a compact city. 3D city models based on these maps are quite effective in understanding what, if this alternative plan is realized, the image of a sustainable city will be. However, enormous time and labour has to be consumed to create these 3D models, using 3D modelli...

Suggestions for Extending the OGC Styled Layer Descriptor ( SLD ) Specification into 3 D – Towards Visualization Rules for 3 D City Models

3D city models can be visualized on the web through OGC W3DS services. However this standard does not support a client-side definiton of visualization rules in order to have a homogeneous visualization of 3D scenes representing data from different servers. But for 2D maps on the web this goal is achieved using a specific language [specification]-the Styled Layer Descriptor (SLD) Specification. ...

The V-City Project

3D geoinformatics have entered the digital age, hesitantly in some areas, and rampantly in others. Google Earth and Microsoft Virtual Earth are household names. However, these projects are limited to textured 3D landscapes, aerial 2D images and a few boxy building envelopes. The V-City project is a European research initiative to surpass these limitations, and create a system for intuitively ex...

Generation and Update of 3D-City Models from Maps and Elevation Data

In this paper we describe a procedure for generating building models from large scale vector maps and laser altimeter data. First the vector map is analyzed. The result is used to mask the elevation data of single buildings and to derive a coarse 3D-description by prismatic models. Afterwards roofs are reconstructed by fitting planar surfaces to obtain a polyhedral model.
