Abstract: From 29th - 30th of October, 2009, the 'Data Management Workshop' was held at the University of Cologne, Germany. This workshop was actively supported by two research projects. The CRC/TR32 'Patterns in Soil-Vegetation-Atmosphere-Systems: Monitoring, Modelling, and Data Assimilation' as well as the CRC 806 'Our way to Europe: Culture-Environment Interaction and Human Mobility in the Later Quaternary', both Collaborative Research Centres of the German Research Foundation (DFG). In addition the workshop was co-organized by the Working Group 5 'Methods for Change Detection and Process Modelling' within the Commission VII 'Thematic Processing, Modelling and Analysis or Remotely Sensed Data' of the International Society for Photogrammetry and Remote Sensing (ISPRS). Since many different scientific communities are facing similar problems in data handling, the aim of the workshop was to bring together a variety of scientific disciplines, which are sometimes recognised as being quite incompatible with one other (e.g. computer sciences, social sciences, geography, physics, pre-history, geoinformatics, archaeology, geosciences, meteorology, and biology). Moreover, the goal was to take into account the perspective of the funding bodies, in our case the DFG. The workshop was based on 11 invited talks and unusual long coffee breaks, parallel to poster sessions to encourage and support discussion. The diverse program attracted nearly 30 poster presentations and approximately 80 participants. The papers and abstracts of the workshop are summarized in the workshop proceedings.

Abstract: The multidisciplinary research unit 'Biodiversity and Sustainable Management of a Megadiverse Mountain Ecosystem in South Ecuador' established a central data management system to provide the members with all gathered scientific data. Additionally, to the database functionality of the system the web based layout is capable to present general information on the research unit to the public and support accounting and administration of the project. All parts of the system are implemented using open-source or free software. A major task is the allocation of a sophisticated and detailed metadata scheme. The standardized ecological metadata language (EML) is used as the basis for metadata information stored in a relational database. The describing datatypes are highly modular and can be expanded if necessary. Data input and searching is implemented through a dynamic webinterface with easy to use forms. This is important to increase the acceptance of the system by users. Searching the database is possible by strings for keywords, authors, etc. or by geographic locations. Except for gridded data, all single values of the datasets are stored in relational tables and thus, it is possible to extract only parts of a whole dataset during data download. While the system is already operational, modifications and new features are continuously implemented.

Abstract: Interdisciplinary research approaches have to run integrative data analyses to realize their full potential. In biodiversity research, the range of relevant disciplines is large, comprising for instance point related genetical analysis, meteorologists covering three-dimensional energy fluxes, and ecologist working on a landscape level. Each discipline employs specific file formats, data syntax, and concepts or terminology, rendering a joint analysis challenging. A successful central data management must be able to harmonize data across disciplines. A necessary condition is the appropriate annotation of primary data with metadata. A sufficient condition is the formalization of the implicit knowledge about data, its semantics. This paper outlines a framework enabling a knowledge-based data and tool access within the Biodiversity Exploratory Information System (BExIS). We address the problem of semantic heterogeneity within the data sets by relating all data items to concepts of a common, upper-level ontology which reflects the relationships between individual ecological topics. The framework’s service oriented architecture allows for seamless integration of external data sources and analysis tools. We describe the idea of ontologybased data and tool access, the framework concept and its service-oriented architecture as well as the process of semantic registration of data, and provide some details on our implementation as well as a discussion of first experiences with this framework.

Abstract: WDC-RSAT is hosted and operated by the German Remote Sensing Data Center, DFD of the German Aerospace Center (DLR) under the nongovernmental auspices of the International Council for Science (ICSU) and is the most recent data center in the WMO-WDC family, in cooperation with the World Meteorological Organization (WMO). WDC-RSAT cooperates with partners in establishing and making use of modern information technologies (e.g. Grid) in order to promote networking. It is already being implemented as a data publication agent for data related to remote sensing of the atmosphere and is thus authorized to assign so-called ‘Digital Object Identifiers’ (DOI) to data sets. The German ICSU WDC’s (WDC-Climate, WDC-Mare, WDC-Terra, and WDC-RSAT) have formed in 2004 the 'WDC-Cluster on Earth System Research' in order to promote interdisciplinary research related to Earth sciences. Following the recommendations of the Committee of Earth Observation Satellites (CEOS), WDC-RSAT is currently establishing in cooperation with NASA a portal for satellite-based atmospheric composition data (ACC) which ultimately will be integrated in the Global Earth Observation System of Systems (GEOSS).

Abstract: The project 'The Role of Culture in Early Expansions of Humans' is funded by the Heidelberg Academy of Sciences and is projected to run for 20 years. The new research centre's aim is to reconstruct the spatial and temporal patterns of the expansions of hominins between three million and 20,000 years ago in Africa and Eurasia. The main goal of the project is to explain the biotic and abiotic reasons for different hominin expansions. Implicit in the current working hypothesis is the assumption that the influence of changing environmental conditions decreased as the importance of cultural and technological innovations grew. To achieve these general objectives a relational spatial information system was developed and implemented containing information about archaeology, palaeontology and physiographic circumstances. In this paper we focus on the technical issues of this database, its functionalities and preliminary implementation in order to assess early human expansions.

Abstract: The pressure on environmental systems is increasing worldwide due to population growth and the consequences of climate change. Adaptable tools and methods are needed to elaborate information, develop understanding and strategies for sustainable use and management of environmental systems. Such tools should assist scientists, natural resource managers, and decision makers in their work by providing (1) sufficient information about relevant drivers, attributes, and factors from measured data, (2) tools and methods for user friendly access and integrated analyses of such data, i.e. environmental information systems (EIS), and (3) tools for estimating additional information not available as measurements, i.e. environmental simulation models. In addition, a seamless and preferably standardized exchange of data between EIS and integrated assessment tools such as simulation models is gaining increasing importance as the amount of available environmental information is growing together with the complexity of current environmental challenges. The research at the Department of Geoinformatics, Hydrology and Modelling at the Friedrich Schiller University of Jena is reflecting the needs described above with the development of a number of software tools. They provide services and assistance for specific spatio-temporal related environmental problems emerging from integrated research projects. In general, all developed tools (1) use open source software wherever possible to be cost effective, (2) are provided as open source software to others, and (3) are highly flexible and adaptable to ensure usability for a wide range of environmental problems. In this paper we briefly present the River Basin Information System (RBIS) – a web-based information management system with a focus on time series and geospatial data. It provides user friendly interfaces for data input and output, powerful visualization components, and an adaptable set of functions for data analysis, data management, and data enrichment. Sample applications from various research projects are used to illustrate that RBIS is an appropriate platform to meet the demands for collaborative and integrated data management.

Abstract: The European Mining Database for North Rhine Westphalia (EMD-NRW) has the objective to present information about the industrial heritage of mining in a GIS-based web portal. Especially in the area of North Rhine Westphalia (Germany) larger coal reserves were important for the development of the industry and particularly influenced the landscape. Concerning the increasing abandonment of these objects and the loss of the cultural industry objects, the preservation of information and the relations between these objects is important. The EMD-NRW system is capable of representing the complex, hierarchical structure of archive data and connecting this data to their geographical location. Several technologies are used to share this information in a web portal. Therefore, comprehensive information is available about every object. All objects are spatially referenced and can be visualized in a map. It is possible to connect the system to other projects by the use of open, compliant techniques. For beginners and experts information are easy to retrieve because of an intuitive design of the graphical user interface.

Abstract: Information management is one important and challenging task in engineering projects. The progress in computer simulation techniques, new measurement techniques in field and laboratory as well as the access to mass of data via the Internet requires new information management strategies beyond traditional database solutions. This paper describes the information management in an ongoing research unit dealing with the coupling of flow and deformation processes for modeling the movement of natural slopes. Based on a generalized information modeling approach using sets of tensors an innovative information management system allows the handling, analysis, reporting, and archiving of any physical state variable on different time and space scale. This leads to an efficient integration/coupling of different models with related information mapping methods as well as information mining approaches for scenario and process identification.

Abstract: The 2007 British Atmospheric Data Centre (BADC) Users Survey examined the skill base of the BADC’s user community. Results indicated a large proportion of users who were familiar with data held in ASCII formats such as comma-separated variables (csv) and there was a high degree of familiarity with spreadsheet programmes (e.g. Excel) for data analysis purposes. These result, combined with the experiences of the BADC staff dealing with user enquiries and assisting data suppliers in preparing data for submission, and the metadata requirements of the BADC, highlighted the need for a new ASCII format to be generated. The BADC-CSV format adheres to metadata conventions covered by the NASAAmes and NetCDF formats, the CF, and Dublin Core metadata conventions, the ISO19115 standard and the metadata requirements of the BADC and its sister data centres within the Natural Environment Research Council (NERC). The format meets end user and data supplier requirements by being a native format for spreadsheet software as well as other commonly used data production and analysis tools (e.g. IDL, MatLab). This paper presents the requirements for the format resulting from the 2007 user survey and data centre requirements, describes the structure of the format and demonstrates the format through short examples. Finally, ongoing work to further develop the format is discussed.

Abstract: In this paper we present a concept for the storage, exchange, presentation, and analysis of geospatial, environmental, and archaeological data with the aim to study and assess the dynamics of early human expansion. We present geographic information systems (GIS), database solutions and web based technologies for handling and processing archaeological and physiographic information. The project deals with a range of variables and file formats from the fields of geology, geomorphology, paleontology, and archaeology presented in vector, raster, and text formats. In order to demonstrate the possibilities of the ROCEEH Out of Africa Database (ROAD), this study presents a unique set of archaeological information sampled from a period between 3Ma and 20Ka covering the region of Southern Africa. The data includes site locations, their geology, and most important, the archaeological, paleo-biological, and climatic data that are accessed for these different locations. To help explaining the spatial distribution of archaeological and paleontological sites, detailed topographic information was provided at scales of 5m, 10m, 25m, 90m, and 1km based on aerial photography, ASTER, and SRTM elevation data. Moreover, bathymetry was provided at a resolution of 1km. Combining these data sets, we show the first spatial and conceptual analysis of the data using ROAD. The results of different research questions show the potential of these methods and give some perspectives for future applications.
