Accepted Answer

This paper aims at providing an overview of visual analytics, its scope and concepts, addresses the most important research challenges and presents use cases from a wide variety of application scenarios.

Accepted Answer

The most important application is also flow visualization, regarding the automotive industry for example optimization of the air resistance of vehicles, optimization of the flows inside a catalytic converter or diesel particle filter, or computation of optimal air flows inside an engine [21].

Accepted Answer

Part of this project will involve characterizing normal and expected traffic patterns and developing models that will predict traffic activity when stimulus to the network occurs.

Accepted Answer

The applications for climate modeling and climate visualization can cover all possible time intervals, from daily weather forecasts which operate in rather short time frames of several days, to more complex visualizations of climate changes that can expand to thousands of years.

Accepted Answer

By common data analysis techniques like knowledge discovery, astronomers can find new phenomena, relationships and useful knowledge about the universe, but although a lot of the data only consists of noise, a visual analytics approach can help separating relevant datafrom noise and help identifying unexpected phenomena inside the massive and dynamic data streams.

Accepted Answer

Situational awareness is the continuous extraction of environmental information, its integration with previous knowledge to form a coherent mental picture, and the use of that picture in anticipating future events.

Accepted Answer

One celebrated example is the Sloan Digital Sky Survey [10] and the COMPLETE project [11], generating terabytes of astrophysics data each day, or the Large Hadron Collider (LHC) at CERN which generates a volume of 1 petabyte of data per year.

Accepted Answer

Depending on the particular case, visual analytics can help to determine the amount of damage, to identify objectives, to assign priorities, and to provide effective coordination for various organizations for more efficient help in the disaster zone.

Accepted Answer

Instead of only solving these problems algorithmically, visual analytics can help to understand the flows, and to interactively change construction parameters to optimize the flows.

Accepted Answer

In the domain of emergency management, visual analytics can help determining the on-going progress of an emergency and can help identifying the next countermeasures (construction of physical countermeasures or evacuation of the population) that must be taken to limit the damage.

Accepted Answer

The authors distinguish between functions that generate hypotheses from data HS : S → H and functions that generate hypotheses from visualizations HV : V → H.Moreover, user interactions UZ , Z ∈ {V,H, CV,CH} are an integral part of the visual analytics process.

Accepted Answer

Exploratory data analysis as the process of searching and analyzing databases to find implicit but potentially useful information, is a difficult task.

Accepted Answer

Data quality and uncertainty is an issue in many domains, ranging from terrorism informatics to natural sciences, and needs to be taken into account when designing algorithms and visualization metaphors.

Accepted Answer

The research challenge is to integrate this massive information flow, provide visualizations that fuse this information to show the current state of the traffic network, and develop algorithms that will detect changes in the flows.

Accepted Answer

According to John Tuckey, tools as well as understanding are needed [3] for the interactive and usually undirected search for structures and trends.

Accepted Answer

The SciDAC program has brought together tremendous scientific expertise and computing resources within the Terascale Supernova Initiative (TSI) project to realize the promise of terascale computing for attempting to answer some of the involved questions [9].
