Over the last years, a high demand for scenario-specific visualizations of 3D urban models has evolved. At the same time, established service specifications do not yet provide the means to define 3D map products and to deliver them in suitable formats, since they are focused on traditional 2D map products. In this paper, we present an approach for the(More)
Interchange of ECG information among different application areas is not possible with just one interchange standard. Bridging between different existing standards maybe possible by using the nomenclature of the Vital Signs Information Representation standard (VSIR) as " repository " for the semantic information content and developing application specific(More)
In this paper we present a web-based platform that makes use of HTML5 technology and WebGL to facilitate public participation in urban planning. It consists of components that enable city administrations to present urban plans to the public and to engage with stakeholders. One of these components uses the open source library X3DOM to visualise 3D(More)
Current 3D data capturing as implemented on for example airborne or mobile laser scanning systems is able to efficiently sample the surface of a city by billions of unselective points during one working day. What is still difficult is to extract and visualize meaningful information hidden in these point clouds with the same efficiency. This is where the FP7(More)
We evaluate three Open-Source WebGL frameworks (X3DOM, three.js and Cesium) and investigate their use for geospatial applications in the Web. Over the course of one year we carried out five case studies and developed different software prototypes using these frameworks. We focus on geospatial applications since they require unique features that bring the(More)
In this paper a new user interface for the processing of big geospatial data in the Cloud is presented. The paper focuses on the processing of Smart City data since this kind of data is inherently large and becomes more and more important for the maintenance and planning of sustainable future Smart Cities. The user interface is facilitated by(More)
