- Konferenzbeitrag3D-Grundwasseranalyse von Bauvorhaben mittels GeoPro3D(Environmental Communication in the Information Society - Proceedings of the 16th Conference, 2002) Hilbring, DésiréeGeoPro is a 3D GIS application for visualising the ground water table and hydrogeological profiles in designated regions for construction sites. The term construction sites comprises single as well as groups of buildings for urban planning and routes for regional planning. GeoPro3D is a tool to detect conflicts between construction sites and the ground water table. To achieve this the user can view and analyse the entire planning situation or interesting parts of the scene in a three dimensional virtual world embedded in a Geographic Information System.
- KonferenzbeitragA Bayesian Approach to Estimation of Metal Flows in Waste Streams(Environmental Communication in the Information Society - Proceedings of the 16th Conference, 2002) Löfving, Erik; Grimvall, AndersMetal contents in waste are normally presented without any measures of uncertainty, and, if such measures are given, they are normally based on subjective judgements. Moreover, it is difficult to analyse existing data sets by employing traditional statistical procedures. The number of analysed samples can be very small and the sampling strategy is often unknown. Outliers are common and it is not unusual that the standard deviation is larger than the mean. In this paper, we propose a method that combines subjective judgement of uncertainty with actual observations to establish uncertainty bounds. The Bayesian statistical framework is used to set up a probability model that reflects our scientific problem, and this provides a theoretical basis for the inference problem.
- KonferenzbeitragA Comparative Eco-balance for Coating Materials with Epoxidised Derivatives(Environmental Communication in the Information Society - Proceedings of the 16th Conference, 2002) Khatib, Chaouki; Marx-Gómez, Jorge; Prötzsch, Silke; Rautenstrauch, ClausThe scope of the presented project was to illuminate and describe the potential environmental impacts which are caused by the production and application of a coating material using epoxidised derivatives. Therefore an appropriate comparative eco-balance in collaboration with the company BIOMEL GmbH located in Dessau (Germany) shall be conducted. Problem definition, approach and results will be given.
- KonferenzbeitragA Decision Support Tool for the Selection of Clean Technologies in SME's(Environmental Communication in the Information Society - Proceedings of the 16th Conference, 2002) Kakaras, Emmanuel; Giannakopoulos, Dionysios; Hatzilau, Christina St.; Angelopoulou, AnnieA methodological approach and the results related to the development and the implementation of a tool for the introduction of clean technologies (CT) to SME's was developed resulting into an innovative and user-friendly software package Decision Support Tool (DST) using an integrated techno-economical full-scale application. The methodological scheme adopted for the design of the DST was based on the formulation of a Clean Technologies database for the Textile Industry, which was developed by a survey of the "clean" textile processes, as well as, on the elaboration of mass/energy balances of the textile processes. The DST was simulated successfully in industrial environment.
- KonferenzbeitragA Floodplain Inventory for the Danube River Basin Based on GIS and Satellite Technologies, with a Special Focus on Geo-referenced Digital Videography(Environmental Communication in the Information Society - Proceedings of the 16th Conference, 2002) Schwarz, Ulrich; Jensen, SvendThere is a long tradition of using remote sensing applications for the inventory of floodplain areas, in this case particularly wetlands, where in English speaking countries videographic techniques have been extensively used. Videography represents a very cost-effective image acquisition and monitoring procedure that can be used in combination with widely available satellite data (Landsat 7), even when digital video data has an inferior geometric quality when compared to high resolution scanner data and orthophotos. In the following article a proposal for an inventory covering the Danubian floodplains with regard to methodology and operational realisation has been made. Accordingly specific applications, as well as the professional technical aspects under different conditions for various users are illustrated.
- KonferenzbeitragA GIS-based Information System for Managing and Analysing Profile Information for the Use in the Water Management Authorities within the State of Baden-Württemberg(Environmental Communication in the Information Society - Proceedings of the 16th Conference, 2002) Haase, Michael; Braun, Peter; Kröger, Joachim; Stegmaier, AndreasProfile data are required for a variety of tasks which have to performed by river authorities. The acquisition of high quality profile data in general is expensive. The results of a survey among users of profile data in the state of Baden-Wuerttemberg, Germany show that digital profile data are not managed uniquely. Due to this fact data loss may easily result. In addition it is very difficult to provide interoperability services for these profile data. Against this background the Ministry of Environment and Traffic of the state of BadenWuerttemberg has contracted the Research Institute for Applied Knowledge Processing at the University of Ulm to design an information system for storing, retrieving and handling profile data. The latter is subject to this paper.
- KonferenzbeitragA GIS-based Route Mapping Tool for Disabled Access in Urban Environments(Environmental Communication in the Information Society - Proceedings of the 16th Conference, 2002) Beale, Linda; Briggs, DavidAccess and mobility are important dimensions of quality of life. For wheelchair users, everyday trips are often fraught with problems with many barriers, imperceptible to the able-bodied, hindering or totally restricting mobility. The MAGUS project developed and tested a decision-making tool that offers information that will assist route planning based upon the situated knowledge of wheelchair users. The study employed social science techniques to investigate and quantify urban barriers, and GIS and computer technologies to translate these into an operational route assessment and modelling package, using dynamic segmentation and network analysis techniques. This tool was applied and tested in Northampton, UK and provides a decision support and mapping tool for planners, and a guidance device to help wheelchair users.
- KonferenzbeitragA Hydrological Monitoring, Forecasting and Warning System for Poland(Environmental Communication in the Information Society - Proceedings of the 16th Conference, 2002) Dreher, Jorge; Fuchs, Martin; Kruszewski, Aleksander; Niedbala, Jerzy; Niwinski, JanuszOne of the main issues of the Emergency Flood Recovery Project in Poland is to develop a Hydrological Monitoring, Forecasting and Warning System for the entire country, which will be implemented subsequently by the Institute of Meteorology and Water Management (IMGW) at the Headquarter in Warsaw, and regional branch offices. The main tasks are to provide effective management of the hydro-meteorological monitoring network, promote uniformity of data carrying, streamline and formalize the access to the information used for flood forecast preparation, digital presentation of current meteorological conditions and forecasts. The System of Hydrology (SH), which is going to be developed for the IMGW, is presented in this paper.
- KonferenzbeitragA Management Information System (MIS) for ‘Sustainability Networks’(Environmental Communication in the Information Society - Proceedings of the 16th Conference, 2002) Posch, AlfredIndustrial recycling networks are very effective in minimizing impact on the environment by building up closed loops of material and energy use within the industrial system. These interorganizational recycling activities between various industries can be a starting point for ‘sustainability networks’, i.e. systems of voluntary but organized cooperation among different stakeholders with the common target of sustainable development of society within a certain region. To work well an overall vision of the sustainability network, it needs to be clearly defined and then translated into strategies and strategic objectives. These, in turn, need to be transformed into operational targets that can be measured by a comprehensive set of environmental, social and economic indicators. This procedure is quite similar to the balanced scorecard approach of Kaplan/Norton, which is considered an appropriate management information system not only for industry but also for sustainability networks.
- KonferenzbeitragA Model for the Utilisation of Natural Resources for Silviculture(Environmental Communication in the Information Society - Proceedings of the 16th Conference, 2002) Schönke, Ulrike; Köchel, PeterA model to determine economic harvesting policies under consideration of certain ecological constraints is presented. The forest is divided into stands and the optimisation task is to formulate a policy to determine, where and how much to fell. Demand is added in comparison with other researchers, which should be satisfied if possible. There are also different places of demand, e.g. lumber mills. Costs arising from harvesting and transportation can vary depending on the location of felling and the location of demand. As an underlying growth model, the presented method uses a matrix giving the transition probabilities of the forest after five years. The suggested approach is simulation optimisation using genetic algorithms. The results of this paper should assist policy managers in preliminary decision making.
