- KonferenzbeitragA survey of regional environmental data sources based on an ISO 19115 profile(Sh@ring – EnviroInfo 2004, 2004) Peccol, Elisabetta; Muzzolini, V.The discovery of existing environmental data and the collection of the related metadata based on a consistent and standard method is a priority. Yet a common problem faced by public and private organisations involved in environmental impact assessment in Italy, is the lack of information about existing environmental data, particularly at local and regional level. A survey of environmental data sources for the territory of the Friuli Venezia Giulia Region has been carried out for the local Regional Authority with the purpose of discovering data sources relevant to environmental impact assessment with priority for geographic and non-geographic datasets. The analysis of the most common metadata standards used to describe environmental data has shown that the ISO 19115 standard is suitable for the description of environmental information resources. Some aspects that could improve the applicability of the ISO norm in the environmental domain are presented. A profile for discovery metadata was developed to allow a standard description of data sources that is applicable to geographic and non-geographic datasets and was implemented in an ISO compliant meta-database.
- KonferenzbeitragKnow how to share and transfer Know-how(Sh@ring – EnviroInfo 2004, 2004) Tochtermann, Klaus; Dösinger, Gisela; Gissing, BernhardExperience shows that the effects leveraged by technology transfer initiatives can be improved in terms of short term success and long term sustainability. A shortcoming of today’s technology transfer initiatives is their character of selective interventions, consisting of a simple shift of knowledge and technologies from producers to consumers. To overcome this shortcoming we develop a number of components to be considered in planning a technology transfer initiative. This paper outlines these components and integrates them to a guideline which helps to select transfer instruments matching the overall objective of an initiative. The guideline which has its origin in a regional development project does not exclusively aim at the transfer of environmentally sustainable technologies but at knowledge and technology transfer in general.
- KonferenzbeitragGlobal evaluation of human risk and vulnerability to natural hazards(Sh@ring – EnviroInfo 2004, 2004) Dao, Hy; Peduzzi, PascalThis paper describes some methodological aspects of the development of the Disaster Risk Index (DRI), a central component of the Reducing Disaster Risk report from the United Nation Development Programme (UNDP/BCPR 2004). The DRI aims to improve understanding of the relationship between development and disaster risk at the global level. The major assumption behind the index is that differences of risk levels faced by countries with similar exposures to natural hazards are explained by socio-economic factors, i.e. by the population vulnerability. The DRI allows the measurement and the comparison of relative levels of risk, exposure to hazard and vulnerability on a country by country basis. The DRI is also a contribution to a more quantitative evidence for planning and decision making in the field of risk reduction and management. This paper focuses on the evaluation of risk for four hazards (cyclones, droughts, earthquakes and floods). Starting from data on exposed population, as estimated using Geographical Information System (GIS), a statistical analysis was carried out to identify the socio-economical indicators reflecting human vulnerability to hazards. To calibrate the risk model, past casualties recorded by the database EM-DAT from the Centre of Research on Epidemiology of Disasters (CRED) 3 were used. The final outputs include a set of indicators for measuring levels of risk on a country by country basis, a global database on hazard frequencies, an evaluation of the population exposed and the identification of socio-economical parameters for estimating human vulnerability to natural hazards.
- KonferenzbeitragThe BEQUEST Framework: the Vision and Methodology of a Collaborative Platform for Sustainable Urban Development(Sh@ring – EnviroInfo 2004, 2004) Deakin, Mark; Curwell, SteveThe concepts of sustainable development that have emerged in the ‘post Brundtland’ era are explored in terms of a vision and methodology of sustainable urban development (SUD). The said vision and methodology of SUD result from the activities of an international network called BEQUEST, funded by the European Commission (EC). The project involved building consensus over the vision and methodology of SUD and sharing this across a wide range of stakeholders. This paper sets out the vision and methodology of the BEQUEST Framework for consensus building between stakeholder interests, represented here in terms of a collaborative platform for the planning, property, design, construction and operational stages of concerted actions on SUD. The paper goes on to examine some impediments to the realisation of the said vision and methodology, including the reluctance of stakeholders to consider either the ecology and equity of urban development, or concern themselves with the environmental, economic and social issues underlying the sustainability of cities. This paper shall suggest that if these impediments are to be overcome, a collaborative platform capable of integrating such matters is needed.
- KonferenzbeitragIMIS – Flexible and reliable data processing using automated task management(Sh@ring – EnviroInfo 2004, 2004) Schulz, Volkmar; van Nouhuys, JoIMIS (“Integrated Measuring and Information System”) is a complex information system which supports the task of minimizing exposure of humans to radioactivity and the radioactive contamination of the environment by informing extensively about radioactive data. To this end IMIS continuously monitors the radioactivity in a large variety of environmental mediums throughout the entire territory of Germany. IMIS gathers data from more than 2000 stationary metering stations, which monitor the radioactivity close to soil, in air and in water. Beyond that, the radioactivity in food, fodder, drinking water and waste water is determined from laboratory samples. All measured values are stored in a central database-cluster. Condat AG is updating IMIS for the German Federal Office for Radiation Protection. The new system will be completed at the end of 2004. With the help of the new IMIS Client-SW, users at 72 widely distributed institutions verify, aggregate, visualize and evaluate the measured values. This is accomplished by creating business charts, geographical maps and tables, which document the radioactive situation. The resulting documents are organized in an integrated document management system and can be accessed via intra-, extra- and on the internet. One of the central features of the new IMIS is its highly flexible task management component, which will be presented in this paper.
- KonferenzbeitragThe Sahel-Doukkala Information Network (SaDIN) - A regional online geoinformation system(Sh@ring – EnviroInfo 2004, 2004) Löwner, Ralf; Souhel, AbdellatifA critical necessity to achieve international standards in public health, sustainable development and land management is to monitor all natural resources, problems and potentialities of a region. With the contribution of the LIFE – THIRD Countries financial instrument of the European Community, the SaDIN project creates a knowledge pool in the centre of the Chouaïb Doukkali University, El Jadida (Morocco), in collaboration with the Data Centre of the GeoForschungsZentrum Potsdam (Germany) and the private enterprise smartcube ltd. (Germany), in order to provide a basis for any sort of environmental investigations. It comprises tools for data acquisition, sample collection and multidisciplinary analysis with a long-term storage database. It addresses fundamental scientific, environmental and anthropological problems of national importance and social relevance. The aim is a regional real-time geoinformation system with worldwide access via Internet and interdisciplinary dynamic content enabling the communication between scientists, technicians and policy makers. These efforts are accompany by broad formations on geoinformatics for human capacity building. The scientific objectives of this project focuses on the evaluation of the potential of aquifers in the region, which supply an arid, yet increasingly densely populated area. These investigations are accompanied by an epidemiological study on the health situation of the local population, which would be seriously affected by groundwater pollution. Another main focus is based on environmental parameters, such as wildlife, vegetation and illegal waste dumps. The knowledge gained in this project will be a source for technology transfer and policy decisions. It is a pilot project, which could serve as an example for similar projects in other regions of northern Africa and beyond.
- KonferenzbeitragSharing Environmental Data with gein ®(Sh@ring – EnviroInfo 2004, 2004) Vögele, Thomas; Kruse, Fred; Karschnik, OliverIn response to EU Directive 2003/4/EC on Public Access to Environmental Information, public administrations need to provide access to all environmental information available. The German Environmental Information Network (gein®), and the Catalog of Environmental Data Sources (Umweltdatenkatalog - UDK) are tools that support environmental agencies in Germany to comply with the directive. Both of them are currently being merged into a new system, gein® 2.0. This system will feature improved an improved user interface, better capabilities for indexing and searching of online information sources, and an extended access to metainformation-systems and databases. In acknowledgement of the close relation of environmental and geospatial information, gein® 2.0 implements a metadata component (UDK 5.0) that is interoperable with the emerging regional, national, and European spatial data infrastructures due to an implementation of the relevant ISO standards and OGC specifications. In addition, new components for spatial information retrieval and the visualization of spatial information will be added. gein® 2.0 implements a flexible modular system architecture, adaptable database interfaces, and a cascading query propagation. As a result, gein ® 2.0 can be used to build a network of multiple information nodes on different levels of the administrative hierarchy. This may be useful for the integration of information providers on the community level, as required by the EU directive. It is expected that like the UDK, gein ® 2.0 will play a leading role to the process of (meta)data and interface harmonization.

- KonferenzbeitragA Fuzzy Compromise Programming Environment for the ecological evaluation of land use options(Sh@ring – EnviroInfo 2004, 2004) Thinh, Nguyen Xuan; Hedel, RalfIn this paper we describe an extension of the Compromise Programming (CP a multiple criteria optimization method) into Fuzzy Compromise Programming (FCP). By linking of Fuzzy modelling, CP and multiple criteria evaluation (MCE) into a Geographical Information System (GIS), we created a Fuzzy Compromise Programming Environment for the ecological evaluation of land use options as an AML-program (Arc Macro Language). After an introduction, a short description of a framework for GIS-based multiple criteria decision analysis is given in section 2. The section 3 describes the methodology of Hierarchical Fuzzy Evaluation. The section 4 deals with the extension of the CP into FCP. Finally, the section 5 reports about application results of the AML-program for the ecological evaluation of land use options in a suburbanisation area.
- KonferenzbeitragAn internet-based spatial Decision Support System for Environmental Data(Sh@ring – EnviroInfo 2004, 2004) Rüppel, Uwe; Gutzke, Thomas; Petersen, Michael; Seewald, GerritThe supervision and controlling of the groundwater situation - especially of largescaled catchment areas - is a complex challenge for all involved participants. The negative effects on the environment as a consequence of insufficient cultivation measures can be dramatically. Beside the extensive hydro-geological influencefactors, the non-uniform, non-consistent and non-shared underlying data management due to heterogeneous organisation structures is a major problem. In addition, specific tools for an efficient realtime evaluation of spatial information do not exist. This paper describes a software system, which allows the distribution and sharing of environmental information between all involved participants using the internet, realised by XML- and trigger-based replication mechanisms combined with a granular controlling of access rights. By using the portal [Grundwasser Online 2004], tables, charts and maps (like groundwater contour lines, differences and aquifer depth) can be generated in realtime on the basis of the whole shared data pool. The evaluated information can be visualised in a map server with various GI-functionalities, which offer the engineers of the water supply companies and the responsible governmental agencies the opportunity to initiate active controlling measures.
