Abstract
Summary The topical issue today is the problem of the effectiveness of the use of geo-information technologies for monitoring of water objects pollution, since ecologically clean rivers and lakes are a prerequisite for ensuring stable and safe water supply for the population. The paper suggests using Python software to process aerospace images taken from Landsat 8 satellite. Normalized Difference Water Index (NDWI) index was also considered for studying of water objects condition. The paper considers the use of the Normalized Difference Water Index - NDWI to determine the presence of water objects in the image using the above-mentioned program. This software allows you to save processed images in the correct format. The satellite method of observing the environment, proposed by the authors, allows us to follow the changes taking place on the surface of the Earth, using space images. The feasibility of using software that allows the processing of aerosp ace data is presented. The use of the NDWI index to determine the availability of water objects, to determine the turbidity and overall ecological status of reservoirs has been certified. A comparative analysis of two images using the index has shown that in the second case, the water object looks brighter and more appropriate to use for further studies.
