    Ambient Air Quality Data Management and Data Integration
    (Environmental Communication in the Information Society - Proceedings of the 16th Conference, 2002) Schimak, Gerald
    Air quality monitoring as well as air quality data management and network integration are difficult tasks to perform. The more complex the tasks are, the easier to handle they get, and transparent mechanisms are needed. Having an experience of about 20 years in the field of air pollution monitoring, we developed strategies and solutions which we implemented in our new system called UWEDAT-NT. UWEDAT stands for a new environmental monitoring system based on Windows NT/2000, primarily used in the field of ambient air quality monitoring, even though the kernel of the system is designed and implemented in such a modular and flexible way, that it is possible to customize this information system in any thinkable way. The following chapters describe the UWEDAT System focusing on the data management tools, quality assurance, data and network integration and the UWEDAT principles.

    Applying semantics in the environmental domain: The TaToo project approach
    (Innovations in Sharing Environmental Observations and Information, 2011) Avellino, Giuseppe; Pariente Lobo, Tomás; Schimak, Gerald; Rizzoli, Andrea Emilio; Dihé, Pascal
    The EU FP7 TaToo project major aim is to bridge the resource discovery gap. This is a well know problem regarding, firstly, the difficulty of discovering resources available on the Web, secondly, the access and possibly the ‘visualisation’ of these resources once discovered. TaToo is trying to solve the problem through a framework (based on semantic concepts) able to store in a knowledge base, meta-information (or metadata) associated with resources. Meta-information is then used by TaToo during the resource discovery process. Meta-information is provided by end users while discovering resources or by resource owners and, as stored in a triplestore, it consists of RDF triples made of Domain Ontologies concepts. Meta-information knowledge base makes possible, together with a reasoner, a resource model for annotation, and a set of Domain Ontologies, a semantically-enhanced resource discovery process. The paper briefly shows the TaToo architecture focusing on the description of those components dealing with semantics. Then, it shows how semantics has been implemented, giving details on the Minimal Environmental Resource Model (MERM) and on the process of integrating Domain Ontologies to realise the ontology framework used in TaToo.

    Fostering the Vision of Information Sharing in Europe
    (Environmental Informatics and Industrial Ecology, 2008) Severin, Ecker; Schimak, Gerald
    Sharing Information (across borders, domains, organisations, etc.) is one of the strategic goals of the European Commission within Framework Programme 6 and 7. It includes the vision of building the Single European Information Space and is a challenging task for research and industry as well as for policy. ORCHESTRA (Open Architecture for Spatial Data Infrastructure in Risk Management, Integrated Project, FP6) as one of the mainstream projects sharing this vision can be seen as a corner stone for applications, enabling information sharing across boundaries. ORCHESTRA clearly and precisely explains the process of building sustainable architectures and infrastructures (ORCHESTRA Book 2008). Furthermore it enables software architects/engineers to derive their (domain specific) applications applying ORCHESTRA rules. By doing so, they will get – more or less for free – interoperability between information systems and can start sharing information and collaboration across borders or organisations. The results produced by ORCHESTRA, namely the RM-OA, the Reference Model of the ORCHESTRA Architecture (Usländer 2008) is based on standards (e.g. ISO/OGC standards) and was recently accepted by OGC (OpenGeoSpatial Consortium) as a best practices paper within the architectural working group. This means that the integration process of ORCHESTRA’s architectural approaches into OGC standards (and affiliated standardisation bodies) has started. Beside the pure architecture many ORCHESTRA services running on the developed ORCHESTRA infrastructure were implemented. These so-called core or architectural services (OA services) are able to support many applications, not limited to the risk management domain. In order to make this visible and prove the reference model, four pilot applications were developed, each of them forming an ORCHESTRA service network integrating several different and diverse information/data sources. Additionally a federated pilot application was developed, showing with support of semantics and the integration of different information networks as well as the possibility of information sharing across different organisations and system borders.

    Introduction to SANY (Sensors Anywhere) Integrated Project
    (Managing Environmental Knowledge, 2006) Havlik, Denis; Schimak, Gerald; Denzer, Ralf; Stevenot, Bernhard
    Sensors Anywhere (SANY) is an FP6 IST-5 Integrated Project dealing with sensor networks research for environmental applications. It aims to contribute to joint European Commission (EC) and the European Space Agency (ESA) “Global Monitoring for Environment and Security” (GMES) initiative by improving the interoperability of in-situ sensors and sensor networks, and allowing quick and cost-efficient reuse of data and services from currently incompatible sources in future environmental risk management applications. This ambitious goal shall be achieved by (1) specifying a (generic) standard open architecture for fixed and moving sensors and sensor networks capable of seamless "plug and measure" and sharing (virtual networks); (2) developing and validating re-usable data fusion and decision support service building blocks and a reference implementation of the architecture; (3) closely working with end users and international organisation in order to assure that the outcome of SANY contributes to future standard(s) applicable to GMES. All SANY architecture specifications shall be publicly available, validated by experts through OGC technical committee and compatible with EU and ESA infrastructure initiatives, such as Infrastructure for Spatial Information in Europe (INSPIRE; standard interfaces with geospatial information). Last, but not the least important, SANY specifications shall be realised in three innovative risk management applications covering the areas of air pollution, marine risks and geo hazards.

    Multiple Dependencies and Scenario Management in Emission Inventories
    (The Information Society and Enlargement of the European Union, 2003) Humer, Heinrich; Winiwarter, Wilfried; Schimak, Gerald
    Assessment of emissions of air pollutants consists of very simple calculations. However, difficulties arise by combining very different sources of input data in a sophisticated structure and to keep these data well organized. We show in this paper an approach to support air quality experts in preparing these input data, to evaluate combinations of abatement options by managing data groups and scenarios, and to provide a quality maintenance tool to the expert group which allows to evaluate and to document all data and algorithms also for a long term observation. The framework of this development was an application service providing (ASP) concept, as several users (e.g., from different Austrian provinces) should be able to share calculation algorithms as well as maintenance of server and database platform.

    openUwedat - a ToolBox Solution for Integrated Air Quality and Traffic Monitoring
    (EnviroInfo Dessau 2012, Part 2: Open Data and Industrial Ecological Management, 2012) Schabauer, Johannes; Schimak, Gerald; Dünnebeil, Gerhard; Litzenberger, Martin
    Environmental Monitoring in urban areas is the base for making good decisions in order to improve quality of life in towns. This requires sensor data integration and fusion of various types of parameters, including periodic timeseries of simple and complex data types like temperature and sound spectrums, as well as non periodic timeseries stemming from traffic data. AIT developed and implemented a novel approach for a combined and integrated monitoring of Environmental Pollution. openUwedat was partly developed under the InnoSens project, which was funded by the European Commission as well as through structure funds of the national government. Within the InnoSens project, this architecture has been tested in the domains of air and noise monitoring caused mainly by traffic. Important to mention is that this monitoring takes place in urban areas and not only on arterial highways. The same software platform is currently in use for the drinking water monitoring network of the City of Vienna and the EU funded project “CARBOTRAF” which focuses on developing specialized aggregating algorithms for traffic prediction and management to minimize CO2 and black carbon emissions. The paper will describe the development of a component oriented architecture based on POA (Pipe Oriented Architecture), its advantages and disadvantages. Furtheron, it will give a short introduction of the toolbox component “Formula 3 scripting language” for flexible and high-performance timeseries processing Other toolbox components like the universal measurement device interface driver “AnySen” and the graphical timeseries editor “GTE” have been published before (Schabauer 2010, Kutschera 2009).

    Source System Integration using the Framework for ORCHESTRA Services
    (Environmental Informatics and Systems Research, 2007) Kutschera, Peter; Ecker, Severin; Schimak, Gerald
    In this paper, an easy to implement, therefore time and cost efficient approach to integrate source systems into an ORCHESTRA service network will be presented. The framework recently developed at the Austrian Research Centers is described in detail and by examples in the following chapters. The basis for this framework was taken from the results of the ORCHESTRA project, which in short is concerned with interoperability of systems among different countries and organizations.

    The TaToo Semantic Case – Requirements, impacts and applications
    (Innovations in Sharing Environmental Observations and Information, 2011) Schimak, Gerald; Božic, Bojan; Kaufmann, Alexander; Peter-Anders, Jan; Dihé, Pascal; Rizzoli, Andrea; Pariente Lobo, Tomás; Avellino, Giuseppe
    Up today numerous semantic developments, starting from ontologies and leading to semantic applications in various (mostly financial or business) domains have been developed and put on the market. Still real suitable systems or application fostering the enrichment of environmental resources in order to make them better understandable and/or discoverable for a broader community are missing or have not be thought of yet. TaToo (Tagging Tools based on a semantic discovery framework, FP7 project, www.tatoo-project.eu ) intends to demonstrate how the enormous amount of environmental information can become better discoverable and understandable for a broad range of user, e.g. from environmental experts up to the man on the street. Clearly upfront to the definition, specification and implementation of the TaToo framework and tools the requirements with respect to environmental resources handled in TaToo (e.g. environmental data, services, applications etc.) have to be defined. TaToo deals with three scenarios, playing a two folded role. On the one hand they are key providers for challenging requirements but they are also the evaluation facility to prove (as domain experts) the results of project. The proposed paper will describe: a) the main categories of requirements (incl. the approach of requirements collection) written down e.g. for tagging, cross-domain annotation and discovery, meta-information, ontologies, etc. b) brief overview on the tools and services for tagging and discovery provided by the TaToo project c) description of Validation Scenario on Climate Twins Regions and its requirements as well as usage of TaToo developments d) the expected impact on Europeans Single Information Space and its environmental society/community

    UWEDAT-LAN – Connecting Environmental Monitoring Devices
    (Informatics for Environmental Protection - Networking Environmental Information, 2005) Schabauer, Johannes; Schimak, Gerald
    This paper describes the environmental monitoring system UWEDAT, which comprises a central host and outstations. In particular, we will focus on the new UWEDAT-LAN station-computer, which manages an outstation and collects data from any kind of measuring device. UWEDAT-LAN was developed during the last 3 years and follows our successful series of station-computers, which started in the early 1980’s. Thus, this new computer combines more than 20 years of experience and technological leadership in the field of environmental monitoring. We will briefly outline the tasks and the technology in this paper and discuss them in the following chapters.
