- KonferenzbeitragData Analysis and Processing of Biomonitoring Data in the Arrow Project for the Evaluation of Ecological State of Surface Waters in the Czech Republic According to WFD EU(Environmental Informatics and Systems Research, 2007) Jarkovsky, Jiri; Kubosova, Klara; Klapka, Radim; Kubik, Vratislav; Racek, Jaroslav; Hodovsky, Jan; Petras, MiroslavThe project ARROW (Assessment and Reference Reports of Water monitoring http://www.cba.muni.cz/arrow/eng) is focused on the implementation of the EU Water Framework Directive in the monitoring of surface waters of the Czech Republic. The project incorporates both WFD EU demands and complex solution of sampling, biological, analytical and ICT problems. The integral part of the project is also the definition and calibration of reference network of sites. The project is based on long term development of this field in the Czech Republic and is related to parallel project of Ministry of the Environment of the Czech Republic connected to monitoring programs. The solution of the project binds many experts from both scientific and commercial institutions in this field. The focus of the presented paper is the data analysis and processing of data of biological communities in biomonitoring networks for the evaluation of the ecological state of the surface water.
- KonferenzbeitragDatabase System of Environmental Monitoring in the Czech Republic(Environmental Informatics and Industrial Ecology, 2008) Racek, Jaroslav; Ludik, Tomas; Ministr, Jan; Sedlackova, JanaThis paper presents the current state of the information system for administration of environmental monitoring data developed by Masaryk University in Brno (MU). The rising environmental database of MU can be considered as unique for the type and the quantity of stored data. The information system running over this database allows the management of monitoring projects, localities and samples and viewing of various data as well as exporting and simple analysis of the data. The paper describes the basic architecture of the developed information system and shows the most important parts of its data model. The system prototype is implemented as a web application for internal use at MU.
- KonferenzbeitragImplementation of Data Sources for Analysis of Obligatory Level of Taxa Determination for Routine Biomonitoring(Managing Environmental Knowledge, 2006) Nemethova, Danka; Jarkovsky, Jiri; Gelnarova, Eva; Kubosova, Klara; Racek, Jaroslav; Hodovsky, JanAlthough taxonomy or generally biological determination is unavoidable indication component in most of ecological risk assessment studies, its implementation in standard methodical guidelines is often limited by complicated structure of biological communities. The species richness thus increases cost of the determination as well as requirements for experts and time. Our aim here is to document feasibility of optimizing reduction of taxonomic units that are necessary to guarantee still representative and safe scenario of risk assessment studies. This analysis should ensure i) acquisition of information on relationship between the communities and their environment, ii) decreased time and financial costs paid for taxonomic determination, iii) prevention of wrong determination with no relevance to the assessed situation. The proposed environmentally-oriented scoring of taxa consists of two steps, both requires also experts from given biological field and therefore are community-specific. First of all, the index of determination quality and the index of taxon indicative power are computed over reference data set. In the second step, the analysis of valences, similarity of species traits and joint occurrence of species are used for their aggregation in taxonomic tree where we can easily find the proper “cut-off” levels. Proper taxonomic level should be characterized by low demand on determination, however accompanied with still clear association with environmental conditions. The proposed scoring of macrozoobenthos taxa was tested over the dataset of more than 600 reference and contaminated sites. The data sources for analysis are databases of the Czech national information systems storing long-term environmental monitoring data. The results will be incorporated in the standard biomonitoring network of the Czech Republic according to implementation rules of WFD EU.
- KonferenzbeitragInformation System of ARROW Project: Assessment of Ecological State of Surface Waters(Managing Environmental Knowledge, 2006) Jarkovsky, Jiri; Racek, Jaroslav; Nemethova, Danka; Pavlis, Petr; Braabec, Petr; Hrebicek, Jiri; Hodovsky, JanThe ARROW (Assessment and Reference Reports of Water monitoring http://www.cba.muni.cz/arrow/eng) project is the project of implementation of EU Water Framework Directive in the monitoring of surface waters of the Czech Republic and covers all aspects of this problem from data sampling to informatics solution (focusing on the ecostat). The project is based on long term development of this field in the Czech Republic and it is carried out under the supervision of the Ministry of the Environment of the Czech Republic. The important part of the ARROW project is the development and implementation of a Czech approach to the evaluation of the ecological state of surface waters using an analysis of monitoring data. The main idea of the system is an approach based on a network of reference sites and robust multivariate modeling of expected environmental and biological conditions (could be called “RIVPACS type”). The approach presented is compatible with the EU Water Framework Directive and will be implemented in the national-wide information system of the ecological state of surface waters of the Czech Republic.
- KonferenzbeitragInteroperability Framework of the Czech Republic in Environmental Information Exchange(Managing Environmental Knowledge, 2006) Racek, Jaroslav; Hrebicek, JiriThere is presented the research project “Analysis and Design of Communication Framework within International Environmental Information Systems” funded by the Ministry of Environment of the Czech Republic, which is solved by the Masaryk University in collaboration with the Czech Environmental Information Agency. It belongs to a set of eEurope projects of Lisbon strategy of European Union (EU). It monitors environmental communication activities and current interoperability with four target groups of the Czech Republic within pan-European environmental information systems. There are discussed an interoperability and communication framework for international environmental information exchange to meet EU required public access to environmental information and the re-use of public sector information and objectives of interoperability for pan-European eGovernment services.
- KonferenzbeitragProcess Analysis of Dynamic Geo-Visualization in Environmental Crisis Management(Environmental Informatics and Industrial Ecology, 2008) Ludik, Tomas; Racek, JaroslavThis contribution describes the results of the research project “Dynamic Geo-Visualization in Crisis Management” supported by the Czech Ministry of Education. The paper is focused on the process analysis in the crisis management, particularly the analysis of the Czech Fire and Rescue Services Act. The analysis is based on using some use case diagrams, process maps, logical data models and CRUD matrixes. Based on the obtained knowledge from this process analysis, an application ontology has been created. This ontology describes the relations among crisis situations, person resources and information, mainly in regard to the geographical structure. The process maps are described by XPLD language. The application ontology is described by OWL language. Using the standards is aimed on reaching high interoperability.
- KonferenzbeitragProposal of Interoperability Framework of the Czech Republic in Environmental Information Exchange(Environmental Informatics and Systems Research, 2007) Hrebicek, Jiri; Nemethova, Danka; Racek, JaroslavThe paper presents new results of the national ComFrame research project (Analysis and Design of Communication Framework within International Environmental Information Systems) funded by the Ministry for Environment of the Czech Republic Working on the ComFrame project since 2005, the Masaryk University has collaborated with the Czech Environmental Information Agency. The basics for the findings were provided by monitoring of environmental communication activities and current interoperability within interested parties (administration bodies, businesses, citizens and academicians) of the Czech Republic. The information exchange within national and pan-European environmental information systems was analysed. Selected eGovernment services in environmental sector, i.e. interoperability and communication framework for national and international environmental information exchange were studied and proposed to meet European Union legislation, taking into account as the requirement of public access to environmental information and the re-use of public sector information as well as objectives of interoperability of Program IDABC for pan-European eGovernment Services.
- KonferenzbeitragWorkflow of Environmental Administrative Processes in Czech Republic(Environmental Communication in the Information Society - Proceedings of the 16th Conference, 2002) Racek, JaroslavThe poster describes a proposed prototype of an information system for environmental administrative processes in the Czech Republic. The main emphasis is oriented on workflow and document flow in public administration of environmental management. Today workflow is seen as the automation of a business process, in whole or part, during which documents, information or tasks are passed from one participant to another for action, according to a set of procedural rules. But there are many differences between business and administrative workflow management systems. This poster presents these differences and contains the proposal of new workflow and document flow system for environmental administration. The proposal is divided into two parts. The first part contains the analysis of system requirements; the second part contains a system design.
