- KonferenzbeitragMultiple Dependencies and Scenario Management in Emission Inventories(The Information Society and Enlargement of the European Union, 2003) Humer, Heinrich; Winiwarter, Wilfried; Schimak, GeraldAssessment 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.
- KonferenzbeitragEvaluation of Environmental Chemicals in Databases: An Example for the Interdisciplinarity between Environmental Informatics and Environmetrics/Chemometrics(The Information Society and Enlargement of the European Union, 2003) Voigt, KristinaThe relationship between environmental informatics and environmetrics/chemometrics is evident as all disciplines want to give a deeper insight into environmental topics (in case of chemometrics into environmental chemical topics). According to the author a strong interaction exists in many fields, like environmental databases and information systems. Databases without their use and evaluation are only data cemeteries. For an effective use of environmental information the data-analysis is of utmost importance. In this paper the mathematical and statistical evaluation of the contents of 12 databases is demonstrated. Environmental chemicals are taken as an example.
- KonferenzbeitragStandardization of Environmental Data and Information Management in the Czech and Slovak Republic(The Information Society and Enlargement of the European Union, 2003) Hřebíček, Jiří; Pitner, Tomáš; Benko, VladimírTwelve years of Czech and Slovak experiences in standardization of environmental data and information management arising from national and European union legislation are discussed in this paper. The standardization process in both countries (the previous Czechoslovak Republic) began in early nineties of the last century and could only be considered as successful if the proposed standards are accepted and used. When creating Czech and Slovak standards, it had to be assured that, as well as having a good technical solution, it was backed up by motivated users people that feel they really need to have the standards – and who are willing to use them.
- KonferenzbeitragRequirements of a Modern Hydrological Workbench Illustrated by the Integrated Data Management Information System WISKI and its Implementation at the Environment Agency of England and Wales(The Information Society and Enlargement of the European Union, 2003) Wood, Simon; Roenick, Christoph; Natschke, MichaelDue to the improvement water management practice and policies, e.g. the new European Water Framework Directive, the requirement for hydrological data in quantity and quality has increased in recent years on a worldwide level. Today, comprehensive developments in information technology form an ideal basis for building modern hydrological information systems. The case study discusses the implementation and use of a hydrological information and management system at the Environment Agency of England and Wales. The implementation of the system has required the data migration of hydrological data measured at over 30,000 Stations and stored in over 140 databases throughout England and Wales to a single database. This allows and supports access for 300 concurrent Agency employees to manage the data to meet the objectives and vision of the Agency and supports data acquisition and provision to and from industry, environmental organisations, academia and individuals for management and improvement of the environment. This paper describes the Hydrological, Meteorological, and Environmental Data Management Software Package WISKI and the implementation of it at the Environment Agency of England and Wales. The software combines the modern standards of data management with a highly sophisticated Windows based application, designed in cooperation with many European Water Agencies, authorities, engineers and hydrologists. The system consists of a central database server for the storage and management of data, and a client application to allow users interact with the data. Data can be viewed and validated using powerful graphical and tabular interface tools, further analysis can be performed using either own or third party statistical and modeling packages. The results can be easily disseminated to other organisations concerned with the management of the environment on a wider level. Developments based on Internet technologies concern the use of thin clients to allow access to hydrological data through the Internet.
- KonferenzbeitragModel of the Object-Oriented Environmental Information – A New Approach in the Environmental Data and Information Management(The Information Society and Enlargement of the European Union, 2003) Sluka, Jan; Hřebíček, JiříUnderstanding differences and connection between the term of environmental data and the term of environmental information are very important for environmental data and information management. The environmental data representing environmental information are usually obtained from authorized monitoring and data collections. From the reason of standardization process European environmental infromation system is designed a object oriented model of the environmental information in the paper. This model issues from definitions of environmental information in Aarhus Convention and Directive 2003/4/EC. It consists of all its classes, which are presented and discussed, in the paper. Quality controlled monitoring process is very import in data processing for further information management in interpretation of environmental data. The role of introduced new models of environmental metrics is discussed in paper also.
- KonferenzbeitragAssessment of Telecommunication-Supported Dynamic Vehicle Routing Strategies(The Information Society and Enlargement of the European Union, 2003) Hilty, Lorenz M.; Rogger, André J.; Hartmann, Frank A.We describe the application of a simulation model in the domain of dynamic vehicle routing. This model allows for the assessment of optimization potentials in terms of distance, cost and energy savings. Telecommunication between trucks and their central dispatchers has made it possible to react to short-term orders and traffic disturbances. Therefore it is advantageous to go from a static to a dynamic strategy of vehicle route planning. Then a company must ask how to deal with orders coming in on short notice and what consequences different strategies to handle these orders have on the length of distances driven and the utilization of trucks. Our simulation model is able to answer this question using a sample of the data from one trucking company for its specific situation. All constraints relevant in practice are used in the form of corresponding parameters such as different capacity limits of vehicles, the number of vehicles, drivers’ working times, etc. An additional parameter makes it possible to vary hypothetically (0-100%) the percentage of orders considered “dynamic”, i.e. the ones that have to be integrated into truck routes that are already proceeding. In this way the relative value of different strategies to solve an instance of the Dynamic Vehicle Routing Problem (DVRP) can be simulated given different dynamic shares. Important output variables include the sum of distances driven, the associated costs for the company and the environmental impact. Our model was used to study a Swiss trucking company as an example. It became apparent that the dynamic share influences the total distance driven very differently depending on the strategy chosen.
- KonferenzbeitragDeveloping Different Environmental Database Applications Using a Generic Software(The Information Society and Enlargement of the European Union, 2003) Hussels, Ulrich; Lüttgert, Matthias; Nagel, JanetMotivated by the requirements of environmental departments and of the federal environmental agency, a generic concept for developing techno-scientific and administration databases was realized with the aim of using only one software for an as large as possible number of different database applications with specific data models. The program combines a configuration module (modelling part) and an administrative module respectively with a quite complete database application. The modelling tool is integrated with the application and guarantees the consistency of those model aspects that are not in focus at each step. The application provides fine graded object structures, historised types, different list types and pointers as well as overall-structures for the management of different data models, data sources and model views. This makes it easy to create even very complex models.
