    Austrian AQD e-Reporting via INSPIRE Services
    (EnviroInfo & ICT4S, Adjunct Proceedings, 2015) Schleidt, Katharina; Magagna, Barbara; Spangl, Wolfgang; Dünnebeil, Gerhard
    To comply with the recently issued AQD e-Reporting data standards by the European Commission (EC) and the European Environment Agency (EEA), the Austrian Environment Agency (EAA) has, together with the Austrian Institute of Technology (AIT), started the development of INSPIRE compliant download services supporting the full requirements of air quality reporting under European Air Quality Directive 2008/50/EC (AQD). Thus, the Austrian air quality data measured under legal requirements, together with the corresponding measurement metadata and reporting relevant information, will soon be available via real time web-services. One difficult question encountered was which INSPIRE download services to use for which of the features encompassed by the reported datasets. For data flow on air quality zones (B) as well as on air quality assessment metadata (D) it was clear that we would provide these data via a Web Feature Service (WFS), namely the OGC compliant implementation GeoServer. For the data flows C (assessment regime) and G (attainment,) which are purely reporting relevant data, we chose to also use the WFS option for simplicity. For the primary air quality data provided under data flow E we decided to use a Sensor Observation Service (SOS), as this service is far better suited for the provision of time series data. However, there is an area of overlap between the two services, pertaining to the measurement metadata. As the features provided by both services are identical, and the only difference in the response being the service response wrapper, the SOS forwards the request to a coupled WFS, and re-wraps the response before providing it to the client. The SOS used in this solution is a new implementation based on the openUwedat-Framework developed by AIT [1]. This framework provides a harmonized way to wrap virtually any source of time series data by configuring a data handler in a documented way. In addition, the framework is able to deal with semantic information pertaining to individual time series [2] to dynamically influence the fields that should be included in the SOS output such as data quality.

    E-Government Working Group for Environmental Information in Austria – Moving towards SEIS
    (Environmental Informatics and Industrial Ecology, 2008) Krammer, Hans-Jörg; Legat, Rudolf; Schleidt, Katharina; Nagy, Michael; Mayer, Johannes
    With the Environmental Information Amendment Act (UIG) 2004 (which entered into force on 14.02.2005), Austria transposed the European Directive 2003/4/EC, which ensued from the Aarhus Convention, at federal level, into national law. “Information providing bodies” of the federal government, as well as the provinces and municipalities, must comply with the new requirements especially within the scope of actively providing environmental information. As the INSPIRE Directive (Annexes I – III) shows, nearly every piece of environmental information has a geographical relevance, which must always be considered when designing environmental information systems according to the requirements of the Environmental Information Directive. According to Art. 10 of the Environmental Information Amendment Act 2004, Umweltbundesamt manages a “Coordination Centre for environmental information“ (KUI). This Coordination Centre assists in the exchange of information between the information providing bodies and proposes suitable measures in order to facilitate access to environmental information for the applicants (i.e. those seeking such information) and henceforth secure the high quality of environmental information. The most urgent function of the Coordination Centre for environmental information is thus the development of “recommendations for structuring available information in compliance with the Directive”. Such systemisation shall ensure that environmental information is progressively made available and disseminated to the public and that this information, according to modern standards and within the meaning of the Recitals and Article 7 of the Directive, shall be made available in particular by electronic information and communication technologies. In order to promote the standardised systemisation of environmental information on Internet portals and to ensure a joint approach for implementing the requirements under the Environmental Information Act 2004, a process of cooperation between the federal government and the provinces (eGovernment process) was initiated within the framework of “platform digital Austria”.

    MORIS – MEDEA or Using Ecological Tools for Monitoring of Meteorological Extreme Events
    (Informatics for Environmental Protection - Networking Environmental Information, 2005) Schentz, Herbert; Schleidt, Katharina; König, Martin; Mirtl, Michael
    MORIS is an information system originally designed for the Austrian part of the UN-ECE “Integrated Monitoring” program. The requirements of an information system for heterogeneous and changing data led us to an object relational data model, with a predefined core ontology and end user defined extensions. This information system has proven to be effective for many different ecological topics, so that we dare say that MORIS is a universal information system for ecological data. Due to our success using MORIS in various ecological fields, when the need of an information system for meteorological extreme events came up, we checked the suitability of MORIS. When we started analyzing this problem, it seemed that “event” is a very broad and imprecise concept, hard to model in a normalised manner. On more detailed analysis, we realized that nature driven events like heavy precipitation or an avalanche are quite similar to man driven events like a campaign or a sample. Once these general decisions have been reached, creating the end-user defined classes and importing the instances turned out to be just as easy as with the ecological topics This leads to our assertion that MORIS is an appropriate tool for monitoring natural ecological events, and that the object oriented data model is an appropriate data-model for data-integration.

    Shared Terminology for the Single Environmental Information System (SEIS)
    (Environmental Informatics and Industrial Environmental Protection: Concepts, Methods and Tools, 2009) Bandholtz, Thomas; Fock, Joachim; Legat, Rudolf; Nagy, Michal; Schleidt, Katharina
    The European conference of the Czech Presidency of the Council of the EU “TOWARDS eENVIRONMENT - Opportunities of SEIS and SISE: Integrating Environmental Knowledge in Europe”1, March 25-27, 2009, Prague, Czech Republic, hosted the eEnvironment Terminology2 workshop about Environmental terminology and its semantics as important instruments for discovery, understanding, and integration of any kind of accessible information. Eleven contributions from five European member states presented domain-specific and interdisciplinary examples and discussed common design issues such as terminology structure models, cross-referencing, symmetric vs. asymmetric multilingualism, identity and reference, publishing terminology in the Web, and linking environmental data to such published terminology. In a final recommendation the participants identified general vocabulary use cases, current trends and future requirements.
