Подбор и анализ индексных изображений, пригодных для дешифрирования растительного покрова в условиях Внутригорного Дагестана.Методы. Исследование проведено на базе разновременных космических снимков высокого пространственного разрешения, полученных съемочной системой спутника серии Sentinel-2, с применением методов цифровой обработки геоизображений. Обработка осуществлена с использованием возможностей геосервиса Google Earth Engine.Результаты. Получены разновременные индексные изображения для территории Внутригорного Дагестана. Проанализированы временные ряды сезонных изменений индексов (NDVI, SAVI, EVI), что позволило выявить фенологические закономерности растительности и на основе этого картографировать растительный покров. Для данной территории созданы схемы дешифрирования растительности, по которым выделены участки: лишенные растительности, травянистая растительность разной степенью густоты, древесная (лиственная и хвойная).Заключение. При изучении растительного покрова по индексным изображениям в разных природных условиях необходимо учитывать природные особенности территории, а также использовать дополнительные источники пространственной информации, включая методы полевых исследований.</p></abstract><trans-abstract xml:lang="en"><p>Aim. Selection and analysis of index images suitable for deciphering the vegetation cover in the conditions of inner mountain Dagestan.Methods. The study was carried out on the basis of multi-temporal satellite images of high spatial resolution, obtained by the imaging system of the Sentinel-2 series satellite, using methods of digital processing of geoimages. Processing was carried out using the capabilities of the Google Earth Engine geoservice.Results. Multi-temporal index images were obtained for the territory of inner mountain Dagestan. The time series of seasonal changes in the indices (NDVI, SAVI, EVI) were analyzed, making it possible to reveal the phenological patterns of vegetation and to map the vegetation cover on this basis. Schemes for decoding vegetation have been created by which areas are distinguished according to the following characteristics: devoid of vegetation, herbaceous vegetation of varying degrees of density or woody (deciduous and coniferous).Conclusion. When studying vegetation cover using index images in a range of natural conditions, it is necessary to take into account the natural features of the territory, as well using additional sources of spatial information including field research methods.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>космические снимки</kwd><kwd>индексные изображения</kwd><kwd>вегетационный индекс</kwd><kwd>Google Earth Engine</kwd><kwd>Внутригорный Дагестан</kwd><kwd>SAVI</kwd><kwd>NDVI</kwd><kwd>EVI</kwd></kwd-group><kwd-group xml:lang="en"><kwd>space images</kwd><kwd>index images</kwd><kwd>vegetation index</kwd><kwd>Google Earth Engine</kwd><kwd>inner mountain Dagestan</kwd><kwd>SAVI</kwd><kwd>NDVI</kwd><kwd>EVI</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работа выполнена в рамках темы ГЗ ИГ РАН № АААА-А19-119022190168-8</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The work was carried out within the framework of the theme of GS IG RAS No. AAAA-A19-119022190168-8</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Henrich V. et al.
