В данном исследовании представлены существующие методы дешифровки аэрокосмических снимков лесов и определение наиболее актуального метода для оценки состояния и управления заповедными лесами, а также иными особо охраняемыми территориями на землях лесного фонда Крыма. / This study presents the existing methods of decoding aerospace images of forests...
Radar remote sensing data are used in a wide range of applications such as the detection and tracking of targets, the characterization of the environment or the estimation of geophysical parameters. These data are usually collected by SAR instruments on-board airplanes or satellites. However, developments in technologies permit radar sensors to be ...
Data capturing multiple axes of tree size and shape, such as a tree's stem diameter, height and crown size, underpin a wide range of ecological research—from developing and testing theory on forest structure and dynamics, to estimating forest carbon stocks and their uncertainties, and integrating remote sensing imagery into forest monitoring progra...
La caractérisation statistique du «fouillis de mer » est un problème important en télédétection radar microondes.Elle repose en général sur des modèles purement empiriques qui ne sont pas directement interprétables en termes d’état de mer et ne peuvent pas se prêter à une procédure d’inversion. Pour modéliser la distribution statistique de l’intens...
L’imagerie radar est utilisée depuis plus de 40 ans pour l’observation de la Terre. Elle permet l’acquisition de données à haute résolution spatiale, sur l’ensemble du globe, de jour comme de nuit et quasi indépendamment des conditions atmosphériques et météorologiques. Même si la réponse radar des surfaces océaniques est en général bien caractéris...
The objective of this paper is to present an approach for mapping irrigated areas at plot scale using the Sentinel-1 radar time series. Over a study site located in Catalonia region of north Spain, a dense temporal series of Si backscattering coefficients were first obtained at plot scale and grid scale (10km x 10km). The S1 time series at plot and...
В 2016 г. была опубликована база данных о фитомассе (стволы, листва, ветви, корни) модельных деревьев основных древесных и кустарниковых видов 22 стран Евразии в количестве 7330 определений, из которых более 70 % приходится на территорию России (http://elar.usfeu.ru/ bitstream/123456789/ 6103/1/Usoltsev_%20Database_en_16.xlsx).

Irrigation plays a significant role in agricultural production in order to meet the global food requirement under changing climatic conditions. To fulfil the high demand of food with an ever-increasing global population, better planning of irrigation is required. Therefore, more focus is being set on the assessment of irrigation performance for imp...
In the context of monitoring and assessment of water consumption in the agricultural sector, the objective of this study is to build an operational approach capable of detecting irrigation events at plot scale in a near real-time scenario using Sentinel-1 (S1) data. The proposed approach is a decision tree-based method relying on the change detecti...
