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)
Two words were presented dichoticly and the subject was required to point to visually presented words that either rhymed with or were semantically related to those words. Task demands were varied in terms of the number and type of stimuli which the auditory and visual words actually matched. Performance was superior when either type of stimulus was(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)
This study investigated the validity of lateral eye movements (LEM) as a measure of the individual differences and task demands aspects of LEM by comparing eye movements to information questions that had no clear hemispheric locus with eye movements to rhyme questions that demanded specific left hemisphere involvement. Fifty subjects were asked to respond(More)
With the success of applications providing geospatial 3D data to end-users via virtual globes and web-based services, the need for accessing more accurate and up-to-date information has come up. Geodata typically comes from different and unrelated sources, whereas users expect a seamless view which respects their specific needs. A modern geo portrayal(More)
