GEODATA PROCESSING AND WEB MAPPING IN VISTULA LAGOON ECOSYSTEM MANAGEMENT

WEB mapping and processing of GIS-type data (geodata) through the Internet becomes the newest technology applied in geosciences and live sciences. Research project entitled “System of the environmental and spatial information as the background for the sustainable management of the Vistula Lagoon ecosystem (VISLA), carried out at the University of Warmia and Mazury in Olsztyn, consisting in implementation of the innovative internet service for the management of environmental resources is presented in this paper. The main aim of the project is joint exploitation of several geodatabases, connecting land information systems (territory adjacent to the lagoon) with water quality information (in situ measurements), including remote sensing technology and finally the use of mathematical modeling to ecological processes analyses. Data models, modes of data acquisitions, integration and presentation of the results in the form of Internet map services are described. Different aspects of project organization and management linked to VISLA system architecture, software resources and procedures leading to web mapping of the results are shown. Specificity of system components and their mutual connections demanding high degree of formalism is presented in the form of UML diagrams and flowcharts. Adopted solutions and results are presented by some examples of thematic services. * Corresponding author.
