Application of GIS-Technologies for Monitoring the Condition of Hydrological Network

摘要

This article discusses major issues and global trends in the organization of hydrological observations. An approach to optimization of the hydrological network based on the use of geographic information systems (GIS) as a tool for processing, analysis and mapping of the hydrological data is offered. The calculation of the criteria of the number of hydrological stations for the European territory of Russia is made, and the main hydrological characteristics of the region are mapped. The results are analysed and the prospects for further research are outlined.
