    • Visualizing Category-Specific Changes in Oblique Photographs of Mountain Landscapes 

      Jean, Frédéric; Albu, Alexandra Branzan; Capson, David; Higgs, Eric; Fisher, Jason T.; Starzomski, Brian M. (The Eurographics Association, 2015)
      Our paper proposes a method for visualizing the spatial distribution of classes for a multi-class image segmentation problem. We apply this method for the case of mountain landscape images, where classes are defined by ...
    • Towards Interactive Definition of Fast Surrogate Models for Geochemical Simulations Using Visual Analysis 

      Jatnieks, Janis; Sips, Mike; Lucia, Marco De; Dransch, Doris (The Eurographics Association, 2015)
      Geochemical models serve wide-ranging geoscientific applications for underground resource exploitation, aquifer remediation, gas storage and similar problems. Such models are time consuming to calculate. Replacing the ...
    • Real-Time Visualization of Urban Flood Simulation Data for Non-Professionals 

      Grottel, Sebastian; Staib, Joachim; Heyer, Torsten; Vetter, Benjamin; Gumhold, Stefan (The Eurographics Association, 2015)
      Perception and understanding of risk in predictive flood simulation data is a key factor in flood risk management. However, scientific visualizations are often hard to grasp for non-professionals. We present a visualization ...
    • Mining Social Images to Analyze Routing Preferences in Tourist Areas 

      Torrisi, Alessandro; Signorello, Giovanni; Gallo, Giovanni; Salvo, Maria De; Farinella, Giovanni Maria (The Eurographics Association, 2015)
      Social media platforms provide a useful source of data for environmental planning. In the last years these data have been exploited to perform social behaviour analysis. This work uses the huge amount of georeferenced ...
    • Probability Maps for the Visualization of Assimilation Ensemble Flow Data 

      Höllt, Thomas; Hadwiger, Markus; Knio, Omar; Hoteit, Ibrahim (The Eurographics Association, 2015)
      Ocean forecasts nowadays are created by running ensemble simulations in combination with data assimilation techniques. Most of these techniques resample the ensemble members after each assimilation cycle. This means that ...
    • Web-Based Visualization of the Global Change Assessment Model 

      Luo, Wei; Chang, Zheng; Kong, Lilian; Link, Robert; Hejazi, Mohamad; Clarke, Leon; Maciejewski, Ross (The Eurographics Association, 2015)
      The Global Change Assessment Model (GCAM) is an integrated assessment tool for exploring consequences and responses to global change. However, the current iteration of GCAM relies on NetCDF file outputs which need to be ...
    • VafusQ: A Visual Analytics Application with Data Quality Features to Support the Urban Planning Process 

      Triana, John A.; Zeckzer, Dirk; Hernandez, Jose T.; Hagen, Hans (The Eurographics Association, 2015)
      Fast changing urban systems pose huge challenges for planners and governments. One major challenge is to provide optimized facilities systems fulfilling all the basic citizen needs such as food, education, security, and ...
    • An Interactive Web-Based Geovisual Analytics Tool to Explore Water Scarcity in Niger River Basin 

      Lei, Ting L.; Liang, Xing; Mascaro, Giuseppe; Luo, Wei; White, Dave; Westerhoff, Paul; Maciejewski, Ross (The Eurographics Association, 2015)
      Assessing the needs for adaptation and mitigation strategies to climate change and variability in Niger River Basin is a key for future development in Western Africa. There are two major challenges in terms of the assessment: ...
    • A Collaborative Web-Based Environmental Data Visualization and Analysis Framework 

      Lukasczyk, Jonas; Liang, Xing; Luo, Wei; Ragan, Eric D.; Middel, Ariane; Bliss, Nadya; White, Dave; Hagen, Hans; Maciejewski, Ross (The Eurographics Association, 2015)
      We present an environmental data visualization framework that features synchronous and asynchronous multi-user interaction with all the benefits of modern web-based applications, such as easy accessibility and cross-platform ...
    • Multi-Purpose Exploration of Uncertain Data for the Video Monitoring of Ecosystems 

      Beauxis-Aussalet, Emma; Hardman, Lynda (The Eurographics Association, 2015)
      Computer Vision is a promising technique for in-situ monitoring of ecosystems. It is non-intrusive and costeffective compared to sending human observers. Automatic animal detection and species recognition support the study ...
    • Spatial Aggregation of Mobile Transect Measurements for the Identification of Climatic Microenvironments 

      Häb, Kathrin; Middel, Ariane; Ruddell, Benjamin L.; Hagen, Hans (The Eurographics Association, 2015)
      Mobile transect measurements retrieve high-resolution observations revealing the spatial variation of atmospheric properties throughout an urban landscape. A sensor platform is moved through a study site with varying urban ...
    • Visualization of 2D Uncertainty in Decadal Climate Predictions 

      Böttinger, Michael; Pohlmann, Holger; Röber, Niklas; Meier-Fleischer, Karin; Spickermann, Dela (The Eurographics Association, 2015)
      In recent years, climate prediction systems based on coupled climate models are used for investigating the climate predictability on a decadal time scale. Based on ensemble simulation techniques applied and hindcast ...
