    Environmental Data Catalogue: Implementation and Data Quality Issues
    (Informatics for Environmental Protection - Networking Environmental Information, 2005) Fischer-Stabel, Peter; Krieger, Rolf; Schäfer, Kerstin; Wannemacher, Stefan
    In Germany the environmental data catalogue was designed as a meta information system for retrieving environmental information held by public authorities. It is providing its user with information about who is having which information at what location. In this paper we discuss some issues concerning the implementation of the environmental data catalogue at public authorities and the management of data quality.

    Functional and Technical Requirements for a Regional Environmental Information System
    (Environmental Informatics and Systems Research, 2007) Fischer-Stabel, Peter; Krieger, Rolf; Schäfer, Kerstin; Wannemacher, Stefan
    In the last decade public authorities have invested large amounts of money and time in metadata management projects in order to provide public access to environmental data held by them. Directive 2003/4/EC on public access to environmental information has enforced these activities. But most of the projects are initiated at a national or state level and are restricted to environmental data held by authorities at these levels. But Directive 2003/4/EC is also of importance for public authorities at a regional or local level. Therefore in this paper we discuss some central issues concerning the dissemination of environmental information at regional and local levels by means of Web-based information systems.

    Open Source GIS – Architecture sharing Data and Knowledge in an UNESCO MAB Biosphere Reserve
    (Sh@ring – EnviroInfo 2004, 2004) Fischer-Stabel, Peter; Wannemacher, Stefan
    Biosphere reserves have three main objectives: conserving biological and cultural diversity; providing models of land management and experimental sites for sustainable development, and serving as sites for research, environmental monitoring, education and training. These three biosphere reserve functions can be implemented only through involving and mobilizing all the structures and stakeholders concerned. Therefore, a biosphere reserve must have the necessary tools to help it reach its various objectives. Geographic Information Systems (GIS) are such tools, explicitly expressed to support management, monitoring and communication between the actors of the reserve. GIS are able to act as platform where relevant knowledge, information (e.g. case studies) and data on different issues can be shared, analysed, searched through databases, and managed, and where synthesized findings, lessons learned and best practices are made available. But, to become accepted as Biosphere reserve by the different stakeholders there is a long and intensive discussion to follow. Accompanying these processes of discussing the benefits of a new Biosphere reserve in the Bliesgau region (Saarland / Germany), within a students project, we developed a GIS – architecture as information platform using the iterative prototyping approach. This was done in close collaboration with the ministry of environment of the Saarland, which is driving the Bliesgau region towards a biosphere reserve. Based on a requirements analysis, a client-server architecture using open source components (Postgres/Postgis, GRASS, ZMapServer UMN, Zope CMS) was set up. Most important point in the development was the implementation of an Internet Map Service as a communication and information tool for the stakeholders participating in the discussion. Visualising maps in an interactive manner is a much more direct and powerful communication tool than displaying lists and tables. In addition, Web-based maps are able to give the different users the same level of information in a way easy to understand and easy to access.
