    A New and Flexible Architecture for the German Environmental Information Network
    (Informatics for Environmental Protection - Networking Environmental Information, 2005) Vögele, homas; Klenke, Martin; Kruse, Fred; Groschupf, Stefan
    Since the year 2000, the German Environmental Information Network gein® provides access to government-owned environmental information of 15 German federal states and the German federal government. In response to the new requirements for public access to environmental information based on EU-directive 2003/4/EC, gein® currently undergoes a complete technical re-design. The resulting new software (InGrid 1.0) will be used to build Portal-U, an improved central information portal which replaces gein®. In addition, InGrid offers state- and municipal authorities a tool to set up their own information portals and to construct a flexible network of interconnected information nodes. This new technical infrastructure is needed to include, as required by the EU-directive, a much larger number of providers of environmental information, including agencies on the local level. It is also needed to be able to provide better access to environmental information that is not yet online or belongs to the so-called “hidden web”. To support direct access to environmental data and metadata, the new system architecture features distributed indices based on highly adaptable database interfaces and a self-administrating P2P communication infrastructure. A number of standardized interfaces, including a web catalog service conforming to OGC standards, enable Portal-U and other information nodes in the network to benefit from and contribute to other data infrastructures, like the German national geodata infrastructure (GDI-DE) and INSPIRE.

    Aufbau eines europäischen Bodeninformations-Portals im Rahmen des eContentplus-Projekts GS Soil als Baustein für SEIS auf Basis von PortalU®-Technologie
    (Integratives Datenmanagement – Beispiele aus der Umweltbeobachtung, 2009) Klenke, Martin; Konstantinidis, Stefanie; Kruse, Fred
    The availability and accessibility of environmental information has become a key concern for public and private bodies within Europe in the recent years. The European Environmental Information Directive (EEID, 2003/4/EC), the Directive for establishing an Infrastructure for Spatial Information (INSPIRE, 2007/2/EC) as well as the newest initiatives of the EU like the Shared Environmental Information System (SEIS) and the Single Information Space for the Environment (SISE) emphasizes the European-wide need to improve the access to environmental information. Especially the web-based supply of the huge amount of spatial environmental data deserves particularly attention because high organisational efforts and financial expenses are necessary to improve the access to this kind of data. While the INSPIRE Directive and its Implementing Rules (IR) give the framework to establish a European spatial data infrastructure, vital obstacles in reference to harmonization and interoperability of data and services as well as in reference to the organisational structure are not removed yet. The project GS Soil, which was handed in as proposal in the eContentplus call 2008 in June 2008, aims to make a contribution to remove these obstacles by establishing a European web portal for soil information (GS Soil Portal). Within the project 34 partners from 17 European Member States are involved. Soil data are thereby provided for all 17 states mainly on national level and partly on regional level. InGrid, the technology of the German Environmental Information Portal PortalU®, will be used as technical base in the project. It will be used to build up a European GS Soil Portal, where all decentralized distributed soil information of the 18 states is bundled.

    Building a Soil Information Portal for Europe based on the PortalU Technology
    (Environmental Informatics and Industrial Environmental Protection: Concepts, Methods and Tools, 2009) Feiden, Katharina; Klenke, Martin; Kruse, Fred; Konstantinidis, Stefanie
    The availability and accessibility of environmental information has become a key concern for public and private bodies within Europe in the recent years. The European Environmental Information Directive (EEID, 2003/4/EC), the Directive for establishing an Infrastructure for Spatial Information (INSPIRE, 2007/2/EC) as well as further initiatives of the EU like the Shared Environmental Information System (SEIS) emphasizes the European-wide need to improve the access to environmental information. Especially the web-based supply of the huge amount of spatial environmental data deserves particularly attention because high organisational efforts and financial expenses are necessary to improve the access to this kind of data. While INSPIRE and its Implementing Rules (IR) give the framework to establish a European spatial data infrastructure, vital obstacles in reference to harmonization and interoperability of data and services as well as in reference to the organisational structure are not removed yet. The project GS Soil “Assessment and strategic development of INSPIRE compliant Geodata-Services for European Soil Data” aims to make a contribution to remove these obstacles by establishing a European web portal for soil information (GS Soil Portal). Within the project 34 partners from 18 European member states are involved and the project is co-funded by the European Community programme eContentplus. The project duration is from June 2009 until May 2012. Overall it will focus on data organisation, data harmonisation as well as semantic and technical interoperability with the objective to produce seamless spatial information in terms of INSPIRE (European Union 2007). Both the description and harmonisation of European spatial soil data and the operation of a corresponding spatial data infrastructure will take centre stage. Out of the 34 partners, soil data are provided for all 18 involved European member states mainly on national level and partly on regional level. That means 67 % of the 27 European Member States will provide soil data for the project. These data build a sufficient base to analyse and improve the access to the different kinds of digital content. As technical base InGrid®, the technology of the German Environmental Information Portal PortalU®, will be used to build up the GS Soil Portal, where all decentralized distributed soil data are bundled. In the GS Soil Portal all soil related information from web pages, over data bases to data catalogues will be made available and accessible. Search results will be ranked and listed in shared result lists and spatial soil data from OGC compatible Web Mapping Services (WMS) and Web Feature Services (WFS) will be visualized in a map viewer.

    Comparison of the Different Instances of the German Environmental Data Catalogue
    (The Information Society and Enlargement of the European Union, 2003) Haase, Michael; Dombeck, Thomas; Neidlinger, Matthias; Barnikel, Günter; Kruse, Fred; Karschnick, Oliver
    Der Umweltdatenkatalog (UDK) ist als Metadateninformationssystem zum Nachweis von Umweltinformationen in der öffentlichen Verwaltung in Deutschland und Österreich eingeführt. Der virtuelle UDK (V-UDK) ermöglicht eine katalogübergreifende Recherche als Internetapplikation über alle 13 Instanzen des UDK hinweg, die von den Ländern und dem Umweltbundesamt (UBA) geführt und gepflegt werden. Der Umweltobjektkatalog (UOK) des Landes Bayern ist ebenfalls an den V-UDK angebunden. Der vorliegende Beitrag schildert wesentliche Ergebnisse einer Studie, die vom Forschungsinstitut für anwendungsorientierte Wissensverarbeitung an der Universität Ulm im Auftrag des Niedersächsischen Umweltministeriums (FAW 2003) durchgeführt wurde. Ziel dieser Studie war es zu eruieren, worin sich die Kataloge in ihrer Gesamtheit unterscheiden (z.B. Menge der erfassten Objekte, Detallierungsgrad der Erfassung, administrative Informationen und direkte Verlinkung dieser Metadaten mit online verfügbaren Umweltinformationen). Aufgrund der bestehenden Heterogenitäten zwischen den Katalogen gelingt es derzeit nicht immer dem Anwender bei einer katalogübergreifenden Recherche die Ergebnisse wohlstrukturiert und übersichtlich darzubieten. Die Studie enthält deshalb Vorschläge zur Vereinheitlichung der Datenerfassung im UDK sowie Möglichkeiten einer verbesserten Strukturierung der Rechercheergebnisse zur besseren Übersicht für den Anwender.

    Current state of the German Environmental Information Portal PortalU®
    (Environmental Informatics and Industrial Environmental Protection: Concepts, Methods and Tools, 2009) Konstantinidis, Stefanie; Kruse, Fred; Klenke, Martin
    The German environmental information portal PortalU® is now more than three years accessible via www.portalu.de for both citizens and environmental experts. This paper aims at drawing up an interim balance of the development from PortalU®. What was the starting point for PortalU®? What was the motivation to build up the portal? Which features offer PortalU® today? And which development perspectives arise for the technology from today’s point of view? Both important technical aspects as well as important organizational and content aspects will be thereby high lighted.

    Easy Access to Environmental Information with PortalU
    (Managing Environmental Knowledge, 2006) Vögele, Thomas; Klenke, Martin; Kruse, Fred; Lehmann, Hanno; Riegel, Thomas
    Since the end of May 2006, PortalU, the new German Environmental Information Portal, is online. PortalU provides one-stop access to government-owned environmental information in Germany. The portal organizationally and technically integrates the access to a large number of heterogeneous and geographically distributed information sources. A user-friendly interface in addition to advanced searchand visualisation tools enables experts and nonexperts alike to find and view texts of national and regional legislation, information about environmental policies and programmes, environmental reports, monitoring data, digital maps, and many other types of environmental information and data. PortalU is part of the administration’s strategy to comply with the Arhus-Convention and EUDirective 2003/4/EC, both calling for better public access to environmental information. From a citizen’s point of view, the portal helps to find relevant information about the national, regional and local environment in a fast and effective way. PortalU replaces the former German Environmental Information Network (gein®) and integrates the Environmental Data Catalogue (UDK).

    Einbindung von Kommunen in das Umweltportal Deutschland am Beispiel des Kommunalen PortalU® Niedersachsens
    (Environmental Informatics and Industrial Ecology, 2008) Kruse, Fred; Klenke, Martin; Uhrich, Stefanie; Giffei, Christiane; Peters, Sybille
    Das Umweltportal Deutschland PortalU® (www.portalu.de) ist bisher ein Portal für Umweltinformationen von Bund und Ländern. Mittelfristig soll es um kommunale Umweltinformationen erweitert werden. Eine direkte Einbindung der Informationsangebote der Kommunen sprengt den Rahmen der derzeitigen organisatorischen Struktur des Portals. Es werden zwei Ansätze dargestellt, wie die organisatorische Struktur erweitert werden kann, um eine Einbindung kommunaler Umweltinformationen zu gewährleisten.

    Estimating the Number of Web Pages of the Environmental Administration in Germany
    (EnviroInfo Dessau 2012, Part 1: Core Application Areas, 2012) Schenk, Franz; Kruse, Fred
    The German environmental information portal PortalU 2 is an access point to a large number of information sources, all from public authorities. The user is offered a single point of entry for queries on a large variety of data with environmental relevance. In this respect, one of the most important tasks in the maintenance of the portal is to guarantee a high degree of relevance for all the different kinds of information sources. In addition to relevance, which often cannot be defined exactly, quantity of information is a measure that normaly can be obtained more easily. While this is generally true for highly structured information like records in a metadata catalogue or entities in database systems, it can be difficult when dealing with unstructured information sources like web pages. In this paper we show the obstacles that we encountered in our examinations on the size of our web page index and present how the information providers respectively contribute to the web page index of the environmental adminstration in Germany.
