- KonferenzbeitragIRMI – An open metadata catalogue for information and resource management(Sh@ring – EnviroInfo 2004, 2004) Kleindienst, HannesToday, internet based information systems are standard solutions for collaborative management of resources and information. Experiences with several applications like the Swiss environmental catalogue envirocat or the Biosafety Clearing House led to the compilation of a list of common requirements. Based on these requirements, IRMI (Information and Resource Management Interface) was developed. IRMI is solely build upon open source components, with PostgreSQL and ZOPE as the major contributions. The primary goal of the IRMI development is to get a flexible metadata catalogue systems which is easily adaptable to application specific requirements. The current development of IRMI focuses on the integration of GIS data.
- KonferenzbeitragEnvironmental information systems - Appropriate for a transfer into upcoming countries in South East Asia?(Sh@ring – EnviroInfo 2004, 2004) Perl, Elke; Vorbach, StefanThis paper analyses possibilities of transferring European software solutions and concepts in the field of environmental information systems to the target region of Southeast Asia. The needs and demands in the target region of Southeast Asia, as identified by a specific survey in Thailand, taken to be representative for the target region, in order to establish the status quo with respect to theoretical concepts and applications. An investigation of EU-funded and German and Austrian research projects and additionally an analysis about European software solutions was carried out, as was in addition European software solutions. A similar analysis of the current position of environmental information systems in the target region was also carried out and revealed a considerable gap in terms of the ability of European software solutions to meet the demands of the target region. It is hoped that this paper will contribute to the transfer of knowledge between Europe and countries in Southeast Asia by pinpointing specific possibilities for using European software in meeting the needs and demands of Southeast Asia.
- KonferenzbeitragEnvironmental information systems for land planning(Sh@ring – EnviroInfo 2004, 2004) Laniado, Eliot; Botta, Marco; Cappiello, Alessandra; Di Guardo, AndreaDecision-making processes in land planning require that information is shared among all the interested subjects. For information sharing to be effective, it is not sufficient to make the information available; it is necessary to make such information easy and convenient to access and understand, using for example online software tools. This paper presents a set of software tools for information sharing: a software for the communication of the procedures, a data and indicators catalogue, and a light geographic information system. The software tools presented are designed, implemented and tested within the LIFE-Environment Project SFIDA to support the elaboration of a plan for sustainable tourism in three Italian municipalities located close to Lake Garda.
- KonferenzbeitragBiological Information System (BIS): Sh@ring Data and Experiences(Sh@ring – EnviroInfo 2004, 2004) Strobl, Peter T.; Blaschka, AlbinThe technologies underlying the BIS project (Strobl/Blaschka/Heiselmayer 2003) enable a scientific information system paying special attention to open standards and platform independence. We believe we should not strive for homogenizing the scientific database landscape using only one single data exchange path, but focus on optimizing interoperability of diverse systems. The current BIS implementation supports taxonomical, syntaxonomical and distribution data, reflecting research projects hosted at our department. The system does not cover all user requirements, but only those which are really needed, since “return of investment” topics played a central role in the design. BIS permits access with various client platforms. Replacing proprietary software with open source software to implement our XML and OOP based approach we anticipated a general trend in the public sector. BIS' technologies are freely available for low-funded research.
- KonferenzbeitragDiscovering the most important factors for communities of soil microarthropods using machine learning(Sh@ring – EnviroInfo 2004, 2004) Demšar, Damjan; Džeroski, Sašo; Krogh, Paul Henning; Larsen, ThomasIn agricultural soil a set of anthropogenic events shapes the ecosystem processes and populations. The risk of impact from anthropogenic sources on the soil environment is almost exclusively assessed for chemicals, although in agriculture other factors like crop and tillage have large impact too. Thus, the farming system as a whole should be evaluated and ranked according to its environmental benefits and impacts. Our starting point is the availability of data sets describing the agricultural events and the soil biological parameters. Using that datasets and machine learning methods for inducing regression and model trees, we produced empirically based models useful for predicting the soil quality in terms of quantities describing the soil microarthropod community from agricultural measures. However, inducing models for predicting soil quality is not our only goal. What we are also interested is to discover additional knowledge on a higher level and identify the most important factors for population densities of springtails and mites and their biodiversity. We do that by preferring smaller and simpler models to bigger and more complex models, while trying to minimize the performance loss of the models at the same time. Using that approach we identify that microarthropod communities are most sensitive to crops and tillage.
- KonferenzbeitragTransfer Of Information Among Water Quality Monitoring Sites: Assessment By An Optimization Method(Sh@ring – EnviroInfo 2004, 2004) Harmancioglu, Nilgun B.; Cetinkaya, Cem Polat; Geerders, PaulAllocation of sampling sites is the initial and the most crucial step of the water quality monitoring network design and redesign process. Several different approaches have been used within the last 20-30 years in the selection of sampling sites. As yet, there are no standard design procedures to accomplish such a network. However, there are some scientific methods which may help to minimize the subjective aspects of design. This paper examines the application of an optimization method that can be used to assess an existing water quality monitoring for information transfer between its sampling sites. The method uses dynamic programming to evaluate the reduction of the number of sampling sites in a basin with respect to different monitoring objectives. The methodology is demonstrated in the case of the Gediz River basin in Turkey.
- KonferenzbeitragGESREAU : development of tools to use with a geographical database for the management of water resources(Sh@ring – EnviroInfo 2004, 2004) Soutter, Marc; Mattei, AlainFrom the beginning of the 90's, the office for water protection, soils and wastes management (SESA) of the Etat de Vaud (Switzerland), in collaboration with the Laboratory of Hydrology and Land Management of the Swiss Federal Institute of Technology in Lausanne (HYDRAM), undertook the development of a global and integrated water resources management system named GESREAU (see [1]). This system is based on an ARGIS/Oracle architecture under Unix, with a periodic export to Windows-based PC (ArcView and Access), and is used on an operational basis since 1996. From summer 2001, a new set of developments was started. The general scope was to provide integrated tools to analyse the hydraulic features of the river network, the hydrological properties of the watersheds, and to link those two kinds of information (see web site in [3]). An upgrade to the latest ESRI products is planned for the end of 2005. Currently, this system makes it possible to manage 5500 km of rivers and 1200 watersheds digitised from paper maps, several hundreds of cross-sections, etc. The present paper describes the set of engineering tools that has been developed within this framework. The targeted application fields are : • simple hydraulic studies, on the basis of the Manning-Strickler formula applied to cross sections, • hydraulic simulations with a widely used model (HEC-RAS), • development and study of longitudinal profiles of rivers, • the integration of a regionalization method to estimate peak flows in all catchments and sub-catchments, • determination of the hydrological characteristics of any sub-catchment and their exportation into files to be used by hydrological simulation models.
- KonferenzbeitragThe Umweltdatenkatalog as a repository for environmental impact studies(Sh@ring – EnviroInfo 2004, 2004) Voell, MathiasIn this article we examine the capabilities of the Umweltdatenkatalog to meet the requirements of the second European Union directive on public access to environmental information; we will show how the UDK can be used as a repository for information on environmental impact assessments.
- KonferenzbeitragMERCURY: New Problems for an Old Pollutant(Sh@ring – EnviroInfo 2004, 2004) Newland, LeoAn increase in the number of health advisories for mercury, especially with regard to consumption of fish and fish products, has created new concerns for human health. The problem is most acute in certain populations (pregnant women, children, etc.) and provides a basis for the limiting of fish consumption. Data show a greater than 30% increase in the number of mercury advisories/bans in the last ten years.
- KonferenzbeitragCITEAIR – Common Information to European Air(Sh@ring – EnviroInfo 2004, 2004) Hodges, Nick; Heich, Hermann-JosefThe development of Europe ́s urban centres is in many ways linked with the development of sustainable mobility options. Changes in behaviour, economic growth or recession and structure of the population are factors that have an immediate impact on transport and mobility patterns. Cities and regions are the place where the most complex challenges in transport and environment need to be solved. Air quality has unquestionably adverse effects on human health. Traffic is the dominant source of environmental impacts in most urban areas. Local and regional authorities must therefore find efficient and integrated solutions for their environmental and traffic problems to improve the quality of life for their citizens. The requirement on European cities and regions to implement the related EU regulations on air quality has led to a multitude of initiatives to develop sustainable solutions, which balance the often competing demands of environmental quality and economic growth. The absence of a common approach for the implementation of these regulations has led to a variety of isolated solutions. This suggests that there is a need for pooling knowledge to developing better and more efficient solutions, solutions which go beyond the obligations of the related EU directives, creating synergies through the share of know-how, knowledge and experiences. This paper presents the content and the approach of the European Project CITEAIR – Common Information to European Air which is co-funded by the INTERREG IIIC programme. The project started in March 2004 and will be finished in February 2007. The main focus of the project is the further development and deployment of IST-tools, methods and policies for the efficient management of the urban environment and to inform the public on the environmental situation in a common format.
