Complex for reception and real time processing of remote sensing data

The basic problems and trends in the development of modern systems for the reception, storage and real-time processing of satellite data are considered. Abrupt increase in the capability of satellite systems, significant increase in the amount of satellite information and its availability, the development of data processing and presentation technologies, and the use of web technologies are discussed. Data sources of modern remote sensing systems of the Earth and the features of their practical use are considered. It is concluded that the most effective way to obtain real-time information from meteorological satellites are satellite stations that receive data in the X-band at a frequency of 8 GHz. The performance characteristics and capabilities of the equipment of the new satellite receiving complex at Krasnoyarsk Science Center are given. Use of up-to-date computer equipment (high-performance servers and storage systems, local area network with a bandwidth of 10 Gbit/s) and logical separation into the stages of data conversion (data reception, primary and thematic processing) provide the construction of a modern scalable data-processing system for remote sensing data. The paper presents the results of the work on creation of specialized software for information and analytical systems for real-time satellite monitoring

Iron and attendant impurities settled from industrial waste water by ferritizing and formation of nanoparticles in batch bacterials culture have been studies. Iron settlement by ferritizing forms magnetic sediment extractable by magnetic separation..

Detection of changes in urban environment based on infrared satellite data

Changes in the microclimate of the urban environment often occur as a result of changes in urban development, artificial changes in the relief, and the cutting down of forest plantations. Due to changes in the urban environment there is a change in the microclimate of the city, which entails a direct change in the land surface temperature. Changes in the urban environment can be detected using space images of different spatial resolution in the visible and far infrared range. Landsat data is currently the most accessible, complete, and open for studying these changes. Thermal imaging is widely used for monitoring urban sites. To increase the spatial resolution, synthesis of Landsat-8 images with higher spatial resolution images of Planet Scope is used, which allows increasing the spatial resolution of surface temperature maps produced from Landsat-8 images from 30 meters to 3 meters. The paper presents the results of an assessment of the land surface temperature in the city of Krasnoyarsk for a two-year period from September 2016 to September 2018 based on the analysis of Landsat-8 and Planet Scope satellite images
