Karten können die Benutzer im Web darin unterstützen, Standorte, Nachrichten, Fotos und andere raumbezogene Objekte explorativ, d.h. gewissermaβen »spielerisch« kennenzulernen. Mit der Veränderung des Kartenausschnitts definiert ein Benutzer implizit räumliche Suchkriterien, die — kombiniert mit inhaltlichen Suchkriterien — einen zweidimensionalen Zustandsraum aufspannen.Er eignet sich, um die Wirkung der angebotenen Navigationshilfen zu überprüfen. Der Beitrag entwickelt hierfür ein Konzept aus Benutzersicht. Dabei werden Kriterien zur Unterscheidung von Anwendungen identifiziert und an konkreten Beispielen aus dem Web illustriert. Anschlieβend werden Anforderungen an die technische Umsetzung als intelligente Clients im Web dargestellt.

Im Jahr 2012 beauftragte das Bundesministerium für Wirtschaft und Technologie das Fraunhofer-Institut für Intelligente Analyse- und Informationssysteme (IAIS) mit einer Big-Data-Innovationspotenzialanalyse für Deutschland. Der Beitrag präsentiert ausgewählte Ergebnisse zu Anwendungen mit Verbraucherdaten, Trendaussagen zur Marktforschung, Technologien und dem Schulungsbedarf an Data Scientists.Im neuen Jahrtausend vollzog sich ein spannender Wechsel in der Art und Weise, wie Daten gesammelt, aufbewahrt und analysiert werden. Während die technische Kapazität der Speichermedien weiter wächst, ist dazu passend eine weltweite und effiziente Infrastruktur entstanden, die neue, umfangreiche Daten in sozialen und technischen Medien vermittelt und verfügbar macht. Angesichts dieser Entwicklung wollte das Bundesministerium für Wirtschaft und Technologie Handlungsoptionen für Wirtschaft, Politik und Forschung aufzeigen und die Anforderungen verschiedener Branchen an Big-Data-Lösungen identifizie ...

In Germany, the data of the Open Street Map project has become available as an alternative to proprietary road networks in commercial business geomatics software and their customers are wondering whether the quality may be sufficient. This paper describes an implemented methodology to compare OSM street data with those of Navteq for all populated roads in Germany. As a unique feature, the presented methodology is based on a matching between the street objects of OSM and Navteq and all steps are fully automated so that they can be applied to updated versions of both data sets. While there are considerable qualitative differences between regions, towns, and street categories, at a national level the relative completeness of objects, their relative precision, and the relative completeness of names are high enough for maps. However, other attributes, which are needed for the computation of catchment areas, are still relatively incomplete.

The LifeWatch Reference Model provides the basis for an interoperable ICT infrastructure for European biodiversity research building on standards whenever feasible. Distinguishing features will be support of workflow for scientific in-silico experiments, tracking of provenance, and semantic support for interoperability. This paper presents the key requirements and the key architectural concepts to satisfy these requirements.

For complex spatial decision problems a combination of software tools for group decision support, individual decision support and geographic analysis is required. The paper describes a respective approach and the integration of tools that were originally developed independently in two teams of Fraunhofer AIS. The first software system, Zeno, is a Java application for the World Wide Web designed to facilitate on-line structured discourses. It allows individuals to classify their contribution into meaningful categories, according to their topic, objectives and group. Groups must be able to evolve their discourse structure as a collaborative undertaking, and be able to modify it as an integral part of the discussion process. The second software system, CommonGIS, provides Java-based web-enabled services for interactive, explorative generation and analysis of thematic maps, particularly including innovative tools for multi-criteria decision making. It will be utilized and extended within the new EC-funded project GIMMI (Geographic Information and Mathematical Models Inter-operability), which will provide a web portal for the analysis of pesticide applications regarding implications to water and soil. Through the integrated application of Zeno and CommonGIS, the entire decision process can be supported: In the early phases qualitative goals, options and constraints are discussed; they are then elaborated into alternative, more formal models. Different variants can be computed and visualized interactively in order to investigate different assumptions or to test the stability and quality of a solution. The entire process with all important alternatives and decisions is explicitly documented in a design rationale so that it can be reconstructed or resumed under modified constraints at any time.

This article is about the GEOeBIZ project which wants to improve business opportunities in geomarketing for small and medium enterprises. The project's central hypothesis is that spatial data infrastructures will move from data catalogues to federated platforms for the development of low cost and low risk applications. To complement the data-retrieval services of the Open GeoSpatial Consortium the project will design, implement and apply both, visual analysis services for geomarketing and e-business services for commercial exploitation. The article proposes a framework and services for visual analysis.

Participatory spatial planning and decision making requires a combination of software tools for group decision support, individual decision support and geographic analysis and presentation. This article presents a respective approach that integrates two software tools which were originally developed independently. One tool, Dito, is a Java application for the World Wide Web designed to facilitate structured argumentation and discourses. The other tool, CommonGIS, provides Java-based web-enabled services for the interactive, explorative generation and analysis of thematic maps, and it also supports multi-criteria decision making. The evolution of the integrated system is reviewed from first experiments in 2001, the resulting requirements and a succession of prototypes up to the latest solution. The focus of the article lies in the design of this solution.

In software engineering, the quality of development and business processes and their models is of utmost importance for (a) the quality of the software products developed and (b) the operational success of the organization. Nevertheless, many organizations neglect these processes and leave the knowledge about them in the heads of their experts. In this paper, we present the indiGo method and platform for eParticipative Process Learning. Furthermore, we present the results of a three case studies for the evaluation of these methods. The results indicate that processes introduced and modeled with process user participation result in process models with higher acceptance and better perceived quality.
