Visualisierung

Visualisierung veranschaulicht Daten und ist ein grundlegendes Werkzeug fĂĽr die Analyse und das Verstehen von komplexen Sachverhalten in unterschiedlichsten Bereichen.

Interaktive Visualisierung erlaubt dem Betrachter ein exploratives „Eintauchen“ in die Daten und schafft die Grundlage für den vom Anwender gesteuerten visuellen Analyseprozess. Die Nutzung, der bei vielen Daten inhärenten räumlichen Bezüge, ist die Basis für umfassende raumbezogene Visualisierungen. Dadurch entstehen intuitiv zu verstehende kartenbasierte Darstellungen, welche in Entscheidungsfindungsprozessen von zunehmender Relevanz sind.

Das Institut beschäftigt sich intensiv mit der Thematik der interaktiven raumbezogenen Visualisierung in unterschiedlichen Anwendungsfeldern. Dazu zählen Controlling, Security, Social Media und das Gesundheitswesen. Die Forschungs- und Entwicklungsarbeiten konzentrieren sich insbesondere auf Geovisual Analytics Anwendungen, auch unter Berücksichtigung von mobilen Endgeräten.

The Exploitation of Raw Materials in Prehistory: Sourcing, Processing and Distribution

This paper addresses the factors that conditioned the choices in lithic resource procurement for tool making at the Late Aurignacian site of Stratzing-Galgenberg (Austria), based on the lithic assemblage from the main area of the site. The raw materials used in the analysed assemblage are varied and partly relate to various local and non-local proveniences. The importance of non-local flint in the assemblage contradicts the distance decay model according to which the amount of a given raw material decreases with the increasing distance from its source. Drawing on the approach developed recently by Lucy Wilson, we examine the predictive ability of “source attractiveness” with respect to terrain difficulty and energy expenditure to understand why some sources were used more than others, using a Geographic Information System (GIS). Our results indicate that terrain difficulty and mobility costs matter and have a better predictive ability than Euclidean distance alone to explain assemblage variability in the Aurignacian of the Middle Danube region.

Optical recording of material cultural heritage (CH) is a multidisciplinary activity where the understanding of cross-disciplinary semantics is vital for a successful completion. In many cases, a lack of understanding of transdisciplinary semantics slows this process down. The end users who are mostly humanities experts lack the technical knowledge of spatial and spectral recording and could therefore demand more than what is actually required or sufficient for the intended CH application. The negotiations between technical experts and the end users are a tedious process. We present a semantic-based decision support system, COSCHKR, that employs reasoning and recommends optimal recording technology(ies) according to the application requirements of the recorded and processed data. COSCHKR is an ontology-based knowledge model that implies the development of semantic technologies within the Semantic Web framework. It represents formalized knowledge of the disciplines involved in the process of optical recording of material CH. The paper describes the applicability of the model in spatial, spectral, and visualization applications and summarises current possibilities and challenges.

Die luxuriös ausgestatteten Wohneinheiten des am Nordhang des Bülbüldağ gelegenen Hanghauses 2 wurden im 3. Viertel des 3. Jhs. durch eine schwere Erdbebenserie zerstört. Statt die Wohnungen wiederaufzubauen, wurden bereits kurze Zeit nach der verheerenden Katastrophe mit Wasserkraft angetriebene Mühlen eingerichtet. Im Befund sind insgesamt acht Wasserradgerinne mit jeweils einer zugehörigen Mühlstube bzw. Werkstatt erhalten. Sie lassen sich drei Bauphasen zuordnen, die in das 4., 5./6. und Ende des 6./Anfang des 7. Jahrhunderts datieren. In der am besten erhaltenen Phase sind insgesamt fünf Räder hintereinandergeschaltet. Neben einer Steinsäge wurden vier Mahlgänge zur Mehlproduktion angetrieben. Eine große Personenanzahl konnte so mit dem wichtigsten Grundnahrungsmittel versorgt werden. Die Mühlenanlage wird in den städtischen Kontext von Ephesos gesetzt und mit anderen Mühlenanlagen verglichen.

Technical study of Germolles’ wall paintings: the input of imaging technique

2016

Virtual Archaeology Review

The Château de Germolles is one of the rare palaces in France dating from the 14 th century. The noble floor is decorated with wall paintings that are a unique example of courtly love spirit that infused the princely courts of the time. After being concealed sometime in the 19 th century, the paintings were rediscovered and uncovered in the middle of the 20 th century and partly restored at the end of the 1990s. No scientific documentation accompanied these interventions and important questions, such as the level of authenticity of the mural decorations and the original painting technique(s) used in the medieval times remained unanswered. The combined scientific and financial supports of COSCH COST Action and DRAC-Burgundy enabled to study Germolles' wall paintings using some of the most innovative imaging and analytical techniques and to address some of the questions raised. The study provided significant information on the material used in the medieval times and on the conservation condition of the paintings. The data collected is vast and varied and exposed the owners of the property to the challenges of data management.

Cultural Heritage (CH) visualisations have to be understood as a combination of research sources, the contemporary historical and cultural context (Zeitgeist), project background and work process. All available information is collected, consolidated, filtered and assembled into a coherent picture. In case of digital 3D reconstructed models, the result is a digital data set that can be processed for different application fields. They are understood as a result of a complex creative process and as a synthesis of a CH research project, its CH context, the available research source material, and the modeling process itself. For all visualisation types in CH different conditions, factors, and basic rules apply to achieve a high quality result. Two examples are presented illustrating the structured view on visualisation projects as such. This paper seeks to differentiate the various research sources being the basis for digital 3D reconstructed models and defines work phases allowing a quality assessment. Furthermore, the potentials of including this structured view into the ontology COSCHKR currently under development is discussed. In combindation with traditional guidelines COSCHKR platform could open up new and flexible approaches.


Location Based Sensing for Health Diagnoses: A Prototype for Personalized Pollen Profiling

Personalized information and forecasts of environmentally triggered medical symptoms are becoming more and more critical, since the numbers of patients suffering from environmentally induced symptoms is still increasing (e.g. allergy or asthma patients). This project aimed at developing a solution to enable gathering personalized pollen exposure information and mapping this information with geospatial data from the personal habitat. This enables personal forecasts based on geospatial information and, when distributed to other suffering individuals, gives them the possibility of avoiding harmful environments. Within an interdisciplinary team of researchers from the medical, engineering, and geoinformatics professions, a system was developed to gather, qualify, and quantify aeroallergen particles (pollen), monitor additional climate parameters, and map this information, together with geospatial information, to the daily habitat of a single individual.
