Visualization of Urban Micro-Climate Simulations
(The Eurographics Association, 2013)Climate simulations range from projections with global coupled models of the earth system down to simulations of small scale phenomena, and can cover time scales between seconds up to thousands of years. This work focusses ... -
Visualisation design for representing bird migration tracks in time and space
(The Eurographics Association, 2013)As increasing numbers of high quality data sets on bird migration become available, systematic means of designing ways of visualising them are needed. In a collaborative study of visualisation scientists and animal ecologists ... -
Rapid Sketch-based 3D Modeling of Geology
(The Eurographics Association, 2013)We present and compare two different approaches for performing rapid 3D geological modeling. The ad-hoc approach is based on a composition of many specialized modeling functions, while the generic approach provides one ... -
BlendGIS: An Open Source tool for 3d and 4d visualization of ecology related spatial data
(The Eurographics Association, 2013)We developed a plugin for the open source modelling, animation and rendering software Blender to import and visualize ecology related spatial data created with the open source GIS QuantumGIS in 3d and 4d. The main goal is ... -
Visualisation Strategies for Modelling and Simulation Using Geoscientific Data
(The Eurographics Association, 2013)We present a number of strategies to visualise a wide range of geoscientific data for the modelling of natural phenomena. Input data sets as well as simulation results of hydrological or thermal processes can be assessed ... -
Environmental Visualization: Applications to Site Characterization, Remedial Programs, and Litigation Support
(The Eurographics Association, 2013)This paper introduces the application of the visualization technology in the USA environmental consulting industry for site characterization, remedial programs, and litigation support. As a tool visualization allows ... -
Determining and Visualizing Potential Sources of Floods
(The Eurographics Association, 2013)In this paper, we visually analyze spatio-temporal patterns of different hydrologic parameters relevant for flooding. On the basis of data from climate simulations with a high resolution regional atmosphere model, several ... -
MO2GEO - a Small Tool for Registration and Visualization of Geological Data
(The Eurographics Association, 2013)Geological data have to be registered according to country-specific standards and visualized in 3D tools. Both topics are addressed by the tool MO2GEO, which is flexible enough to allow the insertion of common national ... -
3D Visualization of Atmospheric Data for Analytical Approaches
(The Eurographics Association, 2013)In the future, climate change will strongly influence our environment and living conditions. Climate simulations that evaluate these changes produce huge data sets. The combination of various variables of the model with ... -
Rendering Technique of Multi-layered Domain Boundaries and its Application to Fluid Flow in Porous Media Visualizations
(The Eurographics Association, 2013)Current visualization techniques for computational fluid dynamics applications are sofisticated and work well in simple geometries. For complex geometries like pore spaces, multiple domain boundaries are obstructing the ... -
Visualizing Saline Intrusion in a Three-Dimensional, Heterogeneous, Coastal Aquifer
(The Eurographics Association, 2013)We visualize remediation scenarios for a coastal aquifer in Oman, where the natural fresh-saltwater interface is negatively affected by groundwater pumping for irrigation. The 3D aquifer is characterized by strong ... -
Using K-Means Clustering for a Spatial Analysis of Multivariate and Time-Varying Microclimate Data
(The Eurographics Association, 2013)In this study, we propose a k-means clustering algorithm combined with glyph-based encoding method to analyze the spatial distribution and dependence of multivariate, time-varying 3D microclimate data. We obtained five ... -
Visual Analytics for Exploring Changes in Biodiversity
(The Eurographics Association, 2013)We report on ongoing work in which we are designing a visual interface to a large database of species observation data. Our design allows the data to be explored and visually summarised by space, time and species, helping ... -
Visual Analytics of the Hydrodynamic Flux for Coastal Flooding Prediction and Management
(The Eurographics Association, 2013)Fifty percent of the earth's population lives within 60 kms of the shoreline. So preventing or mitigating against coastal or estuary flooding is important, especially because of the predicted sea level rise from climate ... -
Animation of Clouds Based on the Interpolation of Weather Forecast Data
(The Eurographics Association, 2014)We present a novel algorithm for interpolating discrete cloud data of numerical weather forecasts over time. The interpolation provides a continuous natural transition of the cloud properties over time intervals of several ... -
