In order to generate 3D worlds in an automated way it is important to solve the problem of integrating existing 2D and 3D data automatically. We explain some of the issues of this problem in this paper. We also introduce mechanisms for automated generation of integrated 3D geo-data sets, as well as a prototype that implements these. It is necessary to(More)
In this paper we show how to efficiently integrate traditional GIS data into terrain models in order to generate complete 3D maps with little overhead for textures. The results meet the requirements for the Web 3D Service (W3DS), a proposal for the standardization for delivering 3D web maps. Our approach is designed to create fully vectorized 3D scenes that(More)
Digital Elevation Models (DEM) and 3D spatial data plays an important role in typical earth science applications. Numerous simulations, e.g. flood modeling, and spatial analysis, requires very exact terrain data. During the acquisition of these data, for an example by means of laserscanning, very large data sets results due to the high measuring point(More)
One major benefit of multi-touch interaction is the possibility for passive observers to easily follow interactions of active users. This paper presents a novel system which allows remote users to perform collaborative multi-touch interaction in a remote face-to-face situation with shared virtual material seamlessly integrated in a videoconference(More)
The objective of TellMaris (IST 2000-28249, www.tellmaris.com) is the development of a tourist information system for mobile clients which is able to display 3D maps. Surveys have shown that 3D maps in some cases can offer a better guidance in unfamiliar environments than conventional 2D maps. In order to achieve this, state-of-the-art technologies in the(More)
