Combining Cluster and Outlier Analysis with Visual Analytics
(The Eurographics Association, 2017)Cluster and outlier analysis are two important tasks. Due to their nature these tasks seem to be opposed to each other, i.e., data objects either belong to a cluster structure or a sparsely populated outlier region. In ... -
How Sensemaking Tools Influence Display Space Usage
(The Eurographics Association, 2017)We explore how the availability of a sensemaking tool influences users' knowledge externalization strategies. On a large display, users were asked to solve an intelligence analysis task with or without a bidirectionally ... -
Guidance for Multi-Type Entity Graphs from Text Collections
(The Eurographics Association, 2017)The visual exploration of graphs encoding relationships between entities of multiple types (e.g., persons, locations,...) supports journalists in finding newsworthy information in large text collections. Journalists may ... -
EuroVA 2017: Frontmatter
(Eurographics Association, 2017) -
From a User Study to a Valid Claim: How to Test Your Hypothesis and Avoid Common Pitfalls
(The Eurographics Association, 2017)The evaluation of visualization methods or designs often relies on user studies. Apart from the difficulties involved in the design of the study itself, the existing mechanisms to obtain sound conclusions are often unclear. ... -
Guidelines and Recommendations for the Evaluation of New Visualization Techniques by Means of Experimental Studies
(The Eurographics Association, 2017)This paper addresses important issues in the evaluation of new visualization techniques. It describes the principle of quantitative research in general and presents the idea of experimental studies. The goal of experimental ... -
Evaluating the Perceptual Uniformity of Color Sequences for Feature Discrimination
(The Eurographics Association, 2017)Probably the most common method for visualizing univariate data maps is through pseudocoloring and one of the most commonly cited requirements of a good colormap is that it be perceptually uniform. This means that differences ... -
Where'd it go? How Geographic and Force-directed Layouts Affect Network Task Performance
(The Eurographics Association, 2017)When visualizing geospatial network data, it is possible to position nodes according to their geographic locations or to position nodes using standard network layout algorithms that ignore geographic location. Such data ... -
EuroRV3 2017: Frontmatter
(Eurographics Association, 2017) -
A Crowdsourced Approach to Colormap Assessment
(The Eurographics Association, 2017)Despite continual research and discussion on the perceptual effects of color in scientific visualization, psychophysical testing is often limited. In-person lab studies can be expensive and time-consuming while results can ... -
Intuitive Colormaps for Environmental Visualization
(The Eurographics Association, 2017)Visualizations benefit from the use of intuitive colors, enabling an observer to make use of more automatic, subconscious channels. In this paper, we apply the concept of intuitive color association to the generation of ... -
Video Compression for Ocean Simulation Image Databases
(The Eurographics Association, 2017)Climate research requires monitoring a large range of spatial and temporal scales to understand the climate system and potential future impacts. Climate simulations are now run with very high resolution (1-10 km gridcells) ... -
Extracting, Visualizing and Tracking Mesoscale Ocean Eddies in Two-dimensional Image Sequences Using Contours and Moments
(The Eurographics Association, 2017)We introduce a system to extract and track mesoscale eddies captured in massive global ocean simulations. The major strength and contribution of our system is its design, which is based on two-dimensional image data ... -
STOAViz: Visualizing Saturated Thickness of Ogallala Aquifer
(The Eurographics Association, 2017)In this paper, we introduce STOAViz, a visual analytics tool for analyzing the saturated thickness of the Ogallala aquifer. The saturated thicknesses are monitored by sensors integrated on wells distributed on a vast ... -
Multivariate Visualization of Oceanography Data Using Decals
(The Eurographics Association, 2017)In this paper, we present our results on the 2016 Compute Canada Visualization Contest, which centers around the visualization of multiple oceanographic data attributes. Our goal is to help researchers better understand ... -
Visual Eddy Analysis of the Agulhas Current
(The Eurographics Association, 2017)Large mesoscale eddies in the ocean can transport a substantial amount of heat and salt over large distances. Using highresolution ICON ocean simulation data, it is possible to detect and track eddies in the ocean and ... -
Visual Study of the Benguela Upwelling System using Pathline Predicates
(The Eurographics Association, 2017)Due to the nutrient-rich water transported to the upper layer of the ocean, coastal upwelling systems are regions especially important for marine life and fishery. In this work, we focus on a visual analysis of the ... -
Visual Characterisation of Temporal Occupancy for Movement Ecology
(The Eurographics Association, 2017)Movement ecologists study aspects of animals' movement, behaviour, and the factors that might drive these. Temporal patterns of local occupancy often reveal the type of usage at a location. We present and apply temporal ... -
An InteractiveWeb-based Doppler Wind Lidar Visualisation System
(The Eurographics Association, 2017)With Doppler wind lidar producing significant amounts of data, providing means to extract relevant information from the data that describes atmospheric phenomena such as rain and low-level clouds is of vital importance. ... -
Setting up Virtual Geographic Environments in Unity
(The Eurographics Association, 2017)We propose a setup for presenting complex heterogenous environmental data in a Virtual Reality environment. After a number of pre-processing steps required to integrate various data sets in a unified context, our workflow ...
