In the face of the world-wide climate change and the high fuel costs the efficiency of combustion motors gain more economical and ecological impact. A central approach for the improvement of the engines is the numeric-simulation. However the simulation based improvement is connected with high complexity. Hence the aim of the project "AVISOM" is to research and develop the task-oriented visualization-techniques for the purpose of development process of combustion motors.

Different interactive views should get researched and developed and included in a complete system. These should make it possible (1) to evaluate analytic, mathematical approximation-functions by means of simulated data points, (2) to integrate interactive optimization-concepts in visualization techniques for multivariate data, and (3) to overlook and to compare a big quantity of simulated or analytic 2D functions.

The improvements apply mainly on the early development phase of an engine. Basic attributes on different parameterization can be analyzed and optimized by means of a multiplicity of simple 1D and 2D simulations.

One of the most important challenges of the emerging Information Age is to effectively utilise the immense wealth of data and information acquired, computed and stored by modern information systems. On the one hand, the intelligent use of available data volumes and information extracted thereof offers large potential to realize technological progress and business success. On the other hand, there exists the severe danger that users and analysts get lost in irrelevant, or inappropriately processed or presented information, a problem which is generally called the information overload problem. Visual Analytics is an emerging research discipline developing technology to make the best possible use of huge information loads in a wide variety of applications. The basic idea is to appropriately combine the strengths of intelligent automatic data analysis with the visual perception and analysis capabilities of the human user.

The goal of this Coordination Action is to join European academic and industrial R&D excellence from several individual disciplines, forming a strong Visual Analytics research community. An array of thematic working groups will be set up by the consortium, which will focus on advancing the state of the art in Visual Analytics. Specifically, the working groups will join research excellence in the fields of data management, data analysis, spatial-temporal data, and human visual perception research with the wider visualisation research community.

This Coordination Action will

(1.) form and shape a strong European Visual Analytics community,

(2.) define the European Visual Analytics Research Roadmap,

(3.) expose public and private stakeholders to Visual Analytics technology and

(4.) set the stage for larger follow-up Visual Analytics research initiatives in Europe.

Coordinator of the consortium is:

Geo-referenced data is getting more and more important due to its many areas of application. In the future every real city will have a digital clone. Big players like Microsoft (via its local live initiative) or Google (via the Google Earth project) are aware of this fact and aggressively push forward to be the number one in this market. Up to now, the 3D cities and landscapes are built up from satellite or airborne data which provide a limited accuracy of about 60cm GSD (ground sampling distance) for satellite and 5 to 10 cm GSD for aerial images on flat surfaces. The next challenge will be the refinement of these 3D city block models by terrestrially acquired data to model building facades or even in-door structures (starting with shopping malls to give access to all showrooms).

In this project we will address the upgrade of an existing 3D city block model (obtained by traditional aerial photogrammetry) using mobile devices. Our understanding of ‘upgrading a 3D block model’ means the augmentation of the facades with more detailed 3D and texture information as well as adding linked meta-information (audio, video, text, web links, …) to the model. The resulting spatial information space can be explored via mobile devices or the Internet.

The 'new' five senses in such a city exploration application are:

- to search

GPS information (plus digital compass) from the mobile phone or PDA are used as a search query in a virtual city model

- to find

a database which stores the virtual city model provides the necessary information to the user

- to see

a visual feedback on his/her display (mobile phone, PDA, ...) is provided to the user

- to explore

the user can explore (find out) additional information in his/her local proximity

- to augment

the user is able to augment the current 3D model by new/additional information like an image for texturing the façade or any other meta-information

The project will enable the creation of a very large 3D city model without the prohibitive costs or the involvement of a large cooperation. With the help of the inhabitants of the city a new path of generating virtual cities will be forged. The model can be used for many applications ranging from tourism and cultural heritage over city planning to emergency support. The combination of 3D computer vision and graphics, hand-held technologies and urban ethology will provide a well rounded project.
