Publicly available sources of geographical data about river networks of European Russia

Abstract

The study provides results of a comparative analysis of several publicly available sources of data about the hydrographic network of the European part of Russia. The comparison was made by a number of quantitative and qualitative characteristics such as: detailed data (detailed network), accuracy (the degree of coincidence with real situation), initial materials used in the creation of a source, presence or absence of the attribute information. These parameters determine the applicability of a variety of sources to solve scientific and applied problems.
