| Abstract [eng] |
This research is devoted to solving the main problem of representation of the assessment results of different types of surface water bodies in the geographical information system (GIS). For the development of such type of infrastructure, the problems arise in a few directions: (a) how to express the complexity, differentiation and variety of surface water bodies, (b) how to extract knowledge for qualitative assessment, and (c) how to integrate new kinds of visualisation possibilities into the GIS. The surface water bodies are of a large spectrum of types with quite dynamically changing properties. The main problem in the realisation of such type of infrastructure is in finding the right relationships between the analysed objects of water resources and visualisation of them in GIS. The main question in this research is in revealing possibilities of integration of functions of digital maps with assessment processes of water bodies. Our approach is based on the development of a deeper knowledge base for defining the required domain properties and representing them in the computer-based ontology in connection with functions of GIS working online. The ontology is used here to design data warehouses' structures, define the relationship functions for expression of the dynamic assessment results in GIS, and map required inputs in user interfaces for online decisionmakers. The algorithms for the main integrating components between the Water Resource Management Information System and GIS have been developed as wrappers, while service provision scenarios enable maintenance of the information with complex features. It becomes easier to realise the decision support process by having the visualisation of the monitoring data assessment and the representation of it in the online working GIS. |
