A Virtual Geographic Environment for the Exploration of Hydro-Meteorological Extremes
(The Eurographics Association, 2021)
We propose a Virtual Geographic Environment for the exploration of hydro-meteorological events. Focussing on the catchment of the Müglitz River in south-eastern Germany, a large collection of observation data acquired via ...
Visualization of Scanned Cave Data with Global Illumination
(The Eurographics Association, 2016)
3D scans of caves are acquired for virtual exploration, quantitative analysis, and communication purposes. Especially when presented to a non-professional audience, near realistic visualization is important because it ...
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 ...
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 ...
Probability Maps for the Visualization of Assimilation Ensemble Flow Data
(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 ...
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 ...
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 ...
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. ...
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 ...
Point-Based Rendering of Forest LiDAR
(The Eurographics Association, 2014)
Airborne Light Detection And Ranging (LiDAR) is an increasingly important modality for remote sensing of forests. Unfortunately, the lack of smooth surfaces complicates visualization of LiDAR data and of the results of ...
