Integrated Energy Monitoring and Visualization System for Smart Green City Development
Sung Ah Kim, Dongyoun Shin, Yoon Choe, Thomas Seibert, Steffen P. Walz,U-Eco City is a research and development project initiated by the Korean government. The project's objective is the monitoring and visualization of aggregated and real time states of various energy usages represented by location-based sensor data accrued from city to building scale. The platform's middleware will retrieve geospatial data from a GIS database and sensor data from the individual sensory installed over the city and provide the browser-based client with the accommodated information suitable to display geo-location characteristics specific to the respective energy usage. The client will be capable of processing and displaying real time and aggregated data in different dimensions such as time, location, level of detail, mode of visualization, etc. The platform's middleware has been developed into an operative, advanced prototype, providing information to a Web-based client that integrates and interfaces with the Google Earth and Google Maps plug-ins for geospatially referenced energy usage visualization and monitoring.

Empiric design evaluation in urban planning
Gideon D.P.A. Aschwanden, Simon Haegler, Frédéric Bosché, Van Luc Gool, Gerhard Schmitt,We propose a system to simulate, analyze and visualize occupant behavior in urban environments by combining parametric modeling and agent-based simulation. A procedurally generated 3D city model, with semantic information about the functions and behaviors of buildings, is automatically populated with artificial agents (i.e. pedestrians, cars, and public transport vehicles). In a simulation the built environment and the agents interact with each other. The system identifies empiric correlations between properties such as: functions of buildings and other urban elements, population density, utilization and capacity of the public transport network, and congestion effect on the street network. Practical applications include the assessment of a) bottlenecks, b) public transit efficiency, c) accessibility of amenities, d) quality of service of public transport and the traffic network, as well as e) the stress level and exhaustion of pedestrians. All these aspects ultimately relate to the quality of life within the given urban areas.

Grammar-based Encoding of Facades
Simon Haegler, Peter Wonka, Stefan Mueller Arisona, Van Luc Gool, Pascal Mueller,In this paper we propose a real-time rendering approach for procedural cities. Our first contribution is a new lightweight grammar representation that compactly encodes facade structures and allows fast per-pixel access. We call this grammar F-shade. Our second contribution is a prototype rendering system that renders an urban model from the compact representation directly on the GPU. Our suggested approach explores an interesting connection from procedural modeling to real-time rendering. Evaluating procedural descriptions at render time uses less memory than the generation of intermediate geometry. This enables us to render large urban models directly from GPU memory.

Visual representations in knowledge management
Martin J. Eppler, Remo A. Burkhard,Purpose – The purpose of this article is to explore the potential of visualization for corporate knowledge management. Design/methodology/approach – The employed methodology consists of a taxonomy of visualization formats that are embedded in a conceptual framework to guide the application of visualization in knowledge management according to the type of knowledge that is visualized, the knowledge management objective, the target group, and the application situation. This conceptual framework is illustrated through real-life examples. Findings – The findings show that there is much room for knowledge management applications based on visualization beyond the mere referencing of experts or documents through knowledge maps. Research limitations/implications – The research implications thus consist of experimenting actively with new forms of visual knowledge representation and evaluating their benefits or potential drawbacks rigorously. Practical implications – The authors encourage managers to look beyond simple diagrammatic representations of knowledge and explore alternative visual languages, such as visual metaphors or graphic narratives. Originality/value – This paper consists of two elements: first, the systematic, descriptive and prescriptive approach towards visualization in knowledge management, and second the innovative examples of how to harness the power of visualization in knowledge management.

Visualization Summit 2007
Remo Aslak Burkhard, Gennady Andrienko, Natalia Andrienko, Jason Dykes, Alexander Koutamanis, Wolfgang Kienreich, Robert Phaal, Alan Blackwell, Martin Eppler, Jeffrey Huang, Mark Meagher, Armin Grün, Silke Lang, Daniel Perrin, Wibke Weber, Vande Andrew Moere, Bruce Herr, Katy Börner, Jean-Daniel Fekete, Dominique Brodbeck,At the first international Visualization Summit, more than 100 international researchers and practitioners defined and assessed nine original and important research goals in the context of Visualization Science, and proposed methods for achieving these goals by 2010. The synthesis of the whole event is presented in the 10th research goal. This article contributes a building block for systemizing visualization research by proposing mutually elaborated research goals with defined milestones. Such a consensus on where to go together is only one step toward establishing visualization science in the long-term perspective as a discipline with comparable relevance to chemistry, mathematics, language, or history. First, this article introduces the conference setting. Second, it describes the research goals and findings from the nine workshops. Third, a survey among 62 participants about the originality and importance of each research goal is presented and discussed. Finally, the article presents a synthesis of the nine research goals in the form of a 10th research goal, namely 'Visualizing Future Cities'. The article is relevant for visualization researchers, trend scouts, research programme directors who define the topics that get funds.
