Popis: To regulate the land relations of water fund lands, high-quality cartographic and geodetic materials are needed, which would make it possible to reproduce the real situation with sufficient completeness and detail. Studies of the structure of the river network are of great economic importance for solving the problems of rational use and protection of water resources. There are 63,119 rivers and streams (linear objects of hydrography) on the territory of Ukraine. The riverbeds are the most dynamic geographical objects, they are constantly shifting. In 30-50 years, the river can move a distance equal to the width of the channel or more. One of the ways to assess the level of aging of maps is directly related to changes in the quantitative characteristics of the contours of the area. Due to the unsatisfactory level of provision of cartographic materials, non-compliance with the deadlines for creating and updating topographic maps on the territory of Ukraine, aging and inconsistency with the current state of about 70% of topographic maps of all scales for more than 15 years. Often cartographic materials are heterogeneous in age not only for individual regions, but even the territory of one district. Web-mapping as an innovative direction of traditional cartography requires not only a single method of creation, but also the visualization of objects of the cartographic basis when changing the scale. Generalization based on valid scientific principles allows to obtain a new cartographic image. GIS-technologies as a possible tool for generalization - the main approach among cartographers and users of GIS-tools in the process of automation of traditional generalization. Finding out the peculiarities of generalization with the involvement of GIS technologies suggests that this process is not fully automated.
