The aim of the article discusses the first experience of creating digital environmental maps and analyzing the spatial distribution of macrophytobenthos in the Yashma coast (Absheron). The role of environmental mapping in studying the state and causes of pollution of seawaters is indicated. A description of the object of study and sources of technogenic impact on the environment in the study area is given. The present study based on identification of the current ecological state of macrophyte growth. Since pollution in coastal water bodies increases every day, studying environmental indicators is relevant for Azerbaijani scientists. Were used QGIS plugin version 2.18.12 “Semi-automatic classification plugin”, originally designed for interpretation of space images obtained from Landsat-3 and Sentinel satellites. Studying the flora of the coasts of the Absheron Peninsula is very important for determining environmental pollution.
