Geographic information mapping methods as a basis for systematization of environmental monitoring data on the Angara River system

This work proposes a model for the application of cartographic and geographic information mapping methods to systematize environmental monitoring data. In particular, based on the results of sampling and study of biological material (roach, Rutilus rutilus (Cyprinidae, Cypriniformes)) from the Angara River system, we obtained an array of information this could be processed and organized on its basis by means of a cartographic presentation of research materials on the state of the environment of water bodies in the Irkutsk region.
