The objective of the study is to assess the state of agricultural seeds (level of weediness) on the
territory of the Krasnoyarsk Agricultural Research Institute of Federal Research Center «Krasnoyarsk
Science Center of the SB RAS» near the village Minino according to satellite data. For this purpose, an
algorithm for obtaining and processing PlaneScope satellite data for calculating the NDVI vegetation
index of agricultural seeds has been developed. On its basis a map of the spatial distribution of NDVI
wheat seeds with different levels of weediness has been created. According to PlanetScope satellite
data, an opportunity to interpret areas of wheat seeds with high and low levels of weediness has been
shown. It has been found that the NDVI value of pure plantation of wheat with a low level of weediness
is greater than the NDVI value of wheat seeds with a high level of weediness Целью работы является оценка состояния сельскохозяйственных посевов (степени
засоренности) на территории Красноярского НИИСХ ФИЦ КНЦ СО РАН вблизи пос. Минино
по спутниковым данным. Для этого разработан алгоритм получения и обработки спутниковых
данных PlanetScope для расчета вегетационного индекса NDVI сельскохозяйственных посевов.
На его основе создана карта пространственного распределения NDVI посевов пшеницы с
различной степенью засоренности. По спутниковым данным PlanetScope показана возможность
дешифрирования участков посевов пшеницы с высокой и низкой степенью засоренности.
Выявлено, что величина NDVI чистых посевов пшеницы и с низкой степенью засоренности
больше величины NDVI посевов пшеницы с высокой степенью засоренности

Classification of Agricultural Crops from Middle-Resolution Satellite Images Using Gaussian Processes Based Method
Safonova, Anastasiia N.; Dmitriev, Yegor V.; Сафонова, A.Н.; Дмитриев, Е.В. (Сибирский федеральный университет. Siberian Federal University, 2018-12)Agricultural applications of the Gaussian process (GP) based techniques is considered. A method of classifying crops from multi-temporal Landsat 8 satellite imagery is proposed. The method uses the model of spectral ... -
Supermassive hot Jupiters provide more favourable conditions for the generation of radio emission via the cyclotron maser instability - a case study based on Tau Bootis b
Weber, C.; Erkaev, N. V.; Ivanov, V. A.; Odert, P.; Grießmeier J.-M.; Fossati, L.; Lammer, H.; Rucker, H. O. (2018)We investigate under which conditions supermassive hot Jupiters can sustain source regions for radio emission, and whether this emission could propagate to an observer outside the system. We study Tau Bootis b-like planets ... -
Transit Lyman-α signatures of terrestrial planets in the habitable zones of M dwarfs
Kislyakova, K. G.; Holmström, M.; Odert, P.; Lammer, H.; Erkaev, N. V.; Khodachenko, M. L.; Shaikhislamov, I. F.; Dorfi, E.; Güdel, M. (2019-03)Aims: We modeled the transit signatures in the Lyman-alpha (Ly-α) line of a putative Earth-sized planet orbiting in the habitable zone (HZ) of the M dwarf GJ 436. We estimated the transit depth in the Ly-α line for an ... -
