Abstract
Since 3rd July 2013, the Surveyor General of Poland leads a Project called Data model and database management system with spatial information on natural environment in aspect of thematic mapping - enviDMS. The Project is co-financed by Iceland, Liechtenstein and Norway through financial support from European Economic Area Grants 2009-2014. The Project is carried by the Head Office of Geodesy and Cartography (GUGiK) in cooperation with the Norwegian Mapping Authority KARTVERKET and a national partner - National Water Management Authority (KZGW). The Project determines an expansion of GUGiK previous works conducted by the National Geodetic and Cartographic Service on the cartographic thematic elaborations related to natural environment such as the Hydrographical Map of Poland in scale of 1:50 000. In accordance to the Act of 17th May 1989 – the Geodetic and Cartographic Law, the Surveyor General of Poland is responsible for development, maintenance and provision of thematic cartographic elaborations in the form of digital maps, including hydrographical maps, sozological maps, geomorphologic maps, agricultural-soil maps, land cover maps, land use maps, maps of technical infrastructure, maps of the average transaction prices of land, maps of the territorial divisions of the country, atlases of Republic of Poland. The Hydrographical Map of Poland in scale of 1:50 000 is a thematic map, which has been prepared by Surveyor General of Poland and Marshalls of Voivodships since 1985. The map presents, in complex manner, the conditions for water circulation, in connection with natural environment, the level of its development by man, as well as its transformations. It is developed on the basis of topographic map, upon which the results of fieldworks and charting of water objects and phenomena, soil permeability, and a lot of information related to management of water resources, assessment of water quality, as well as data concerning hydrosphere monitoring network. The thematic content of the map consists of the following groups of elements, arranged at several levels of information, among others: topographic watersheds, surface waters, underground water outflows, first level of underground water, soil permeability, phenomena and water management facilities, hydrometric points for stationary measurements. Hydrographical Map in scale of 1:50 000, in the form of analogue printout, is one of final products of the complex, thematic environment executed in GIS technology. The main challenge of the enviDMS Project is to develop a data model with its management system, which enables a widespread access and use of spatial information on natural environment in the scope of hydrographical and hydrological spatial data directly through the appropriate imports of data or via web services (WMS, WMTS). New data model shall be developed as an application schema including UML diagrams, catalogue of objects and XML schema. Besides that, the quality model and the catalogue of cartographic symbols shall be developed. Other activities within Project involve the harmonization, integration and standardization of data and services through the use of reference registers, in particular topographic database, as well as coordination of activities according to the model of national information infrastructure. Furthermore, for selected test areas, thematic spatial data will be collected more detailed scale of 1:10 000. The need to obtain data of greater accuracy is the result of intensive exploitation of the natural environment in highly urbanized and industrialized areas. The poster shall present the new approach to hydrographic mapping in Poland taking into account data modelling, mapping, functional and technical requirements of database management system issues.
