    Seismic inhomogeneities in the upper mantle beneath the Siberian craton (Meteorite profile)
/ V.D. Suvorov [et al.] // Russian Geology and Geophysics. - 2013. - Vol. 54, Is. 9. - pp. 1108-1120, DOI 10.1016/j.rgg.2013.07.023 . - ISSN 1068-7971

Nuclear explosion -- Seismic profile -- Siberian craton -- Upper mantle

Аннотация: The upper-mantle structure was studied from first-arrival data along the Meteorite profile, run using underground nuclear explosions. Unlike the layered, slightly inhomogeneous models in the previous works, emphasis was laid on lateral inhomogeneity at the minimum possible number of abrupt seismic boundaries. We used forward ray tracing of the traveltimes of refracted and overcritical reflected waves. The model obtained is characterized by considerable velocity variations, from 7.7 km/s in the Baikal Rift Zone to 8.0-8.45 km/s beneath the Tunguska syneclise. A layer of increased velocity (up to 8.5-8.6 km/s), 30-80 km thick, is distinguished at the base of seismic lithosphere. The depth of the layer top varies from 120 km in the northern Siberian craton to 210 km in its southeastern framing. It has been shown that, with crustal density anomalies excluded, the reduced gravity field is consistent with the upper-mantle velocity model. В© 2013.

    Observations of hydrophysical characteristics of stratified salt lake shira (Siberia) as an important part of its environmental monitoring
/ L. A. Kompaniets, T. V. Iakubailik // International Multidisciplinary Scientific GeoConference Surveying Geology and Mining Ecology Management, SGEM. - 2015. - Vol. 2: 15th International Multidisciplinary Scientific Geoconference and EXPO, SGEM 2015 (18 June 2015 through 24 June 2015, ) Conference code: 153969, Is. 3. - P635-642 . -
Аннотация: To understand the mechanisms of formation of water quality it is necessary to study both biological and chemical properties of a lake as well as its hydro regime. For many years researchers have focused on the study of chemistry and biology of Lake Shira (situated in Siberia), but a detailed investigation of its hydro regime has become possible only recently with the development of modern measuring instruments. Using the latest generation of measuring devices we have obtained the hydrophysical characteristics of the stratified salt lake in situ (air and water temperature, wind strength and direction, water velocity). Relationships between the measured data have allowed us to analyze the flow in the lake as a whole, thus outlining the problem of determining lake ecological status in the period under observation. © SGEM2014.

    Evaluation of seismic hazard using seismic microzonation techniques
/ E. Bodyakin, S. Peretokin, K. Simonov // CEUR Workshop Proceedings : CEUR-WS, 2017. - Vol. 1839: 2016 International Conference Mathematical and Information Technologies, MIT 2016 (28 August 2016 through 5 September 2016, ) Conference code: 127940. - P16-25 . -
Аннотация: It was shown the technique of seismic hazard assessment based on comprehensive use of methods of seismic microzonation. This technique consists of four steps. The first step is to collect geological, seismological, geophysical and topographic information. Each layer according to geological engineering survey and geophysical work are assigned physical and mechanical properties (density, limit shear stress) and the P-And S- wave velocity. Next (step 2) after visualization and examination input data using GIS technologies 3D modelling of the geological environment is performed (it is created a grid each point of which is referred to coordinates of the site). The number and depth of soil are set in each point based on geological drilling data. Then (step 3) at each point seismic intensity are calculated using instrumental methods including the method of acoustic impedance and computer simulation (GRUNT program). At the last stage according to the analysis of the results of theoretical and instrumental methods seismic microzonation map are created using GIS technologies. The procedure of constructing maps uses different methods of selection areas with the same seismic hazard (kriging, spline interpolation).

    Dynamo models created on the planets under the influence of tidal forces of the satellite and the sun
/ V. A. Kochnev // International Multidisciplinary Scientific GeoConference Surveying Geology and Mining Ecology Management, SGEM : International Multidisciplinary Scientific Geoconference, 2017. - Vol. 17: 17th International Multidisciplinary Scientific Geoconference, SGEM 2017 (29 June 2017 through 5 July 2017, ) Conference code: 130800, Is. 62. - P899-906, DOI 10.5593/sgem2017/62/S28.115 . -
Аннотация: It is known that the movement of the liquid core creates electric currents, inducing a main magnetic field of the planet. The liquid core of the high temperature becomes ionized plasma (plasma), which It is quasi-neutral (not neutral) - by definition. One of the major geodynamo questions: what is the source of strength, causing fluid movement in the core of the planet? Many authors have investigated geodynamo: planetary rotation around its axis, the temperature difference and pressure as well as the Coriolis force. Moffatt (1980), at the end of his book, as expressed the problem mentioned above “… For example, it is not yet known that the ultimate source energy is the basic movements of the Earth’s disk Dynamo”. In this study, the role of the driving forces of the liquid core considered tidal forces created axial rotation of the planet and the influence of external objects (the Sun and planets, satellites). The value of the tidal force on the equator of the planet depends on the radius and the period of the axial rotation of the planet, mass, radius and the orbital period of the satellite around the planet. The paper presents the formula and the results of the calculation of tidal forces and forecast the relative values equatorial magnetic fields of the planets all the planets of the solar system. The interpretation of the results illustrated with drawings. The new version of the dynamo It helps to explain the reasons high intensity magnetic Jupiter's field compared to Saturn’s fields, Uranus and Neptune, and much more Earth field intensity compared with fields of Venus, Mercury and Mars. The calculations of the correlation values the magnetic field at the equator: on the model according to the forecast and observations on the planets. Correlation coefficient is 0.997, that indicates a close relationship observed and estimates fields, and this is indirect evidence of the correctness of the adopted model. © SGEM2017 All Rights Reserved.

    Analysis of the velocity profile in lake shira in summer using principal component analysis
/ O. Voldko, L. Kompaniets, L.

Аннотация: The development of modern technologies allows us to solve the problem of carrying out long-term measurements of velocity and temperature in lakes. The long-term local measurements of velocity have been conducted in Lake Shira (Khakassia) in the period 2014-2015.The velocity profile along the column of the liquid in Lake Shira occurs due to density summer stratification and wind. The horizontal velocities vary greatly in depth as well as in time. The principal component method has been performed to analyze the horizontal velocities. This method is widely used to evaluate complex space-time structures, since it allowsto describe the data compactly.The obtained data have been decomposed into empirically determined modes with different scales. This makes it possible to extract dominant modes in the data and in some cases to determine the corresponding physical process.The first empirical modes in all measures are analogous to the Ekman spiral of the stationary motion of a homogeneous liquid and the remaining modes can correspond to internal waves. © SGEM2017 All Rights Reserved.

    Modelling the static stress–strain state around the fan-structure in the shear rupture head
/ B. G. Tarasov [et al.] // Appl. Math. Model. - 2018. - Vol. 57. - P268-279, DOI 10.1016/j.apm.2018.01.020 . - ISSN 0307-904X
Аннотация: The mathematical model of an equilibrium fan-structure in the interface between two elastic blocks, simulating the shear rupture head in a hard rock under high confining pressure, is constructed. The stress–strain state far from the fan-structure is analyzed with the help of a solution of the problem on edge dislocation. The fan length is estimated using this solution. The model of formation of two oppositely directed fans due to the localized action of tangential stress, which pushes two edge dislocations with antiparallel Burgers vectors, is proposed. In complete formulation, the problem on an equilibrium fan-structure in the interface between infinite elastic half-planes is analyzed by means of original method of superposition of dislocations, leading to two nonlinear integral equations in the fan zone. To solve them numerically, the method of successive approximations is applied. Based on this method, fields of stresses and displacements around the equilibrium fan modelling of a deep-seated shear rupture in the seismogenic zone of the Earth's crust are computed. Such fields can be used, when setting the initial data in the analysis of dynamics of the fan-shaped mechanism. © 2018 Elsevier Inc.

    Empirical orthogonal analysis of temperature and vertical velocity in lake Shira
/ O. S. Volodko, L. A. Kompaniets, L. Gavrilova // International Multidisciplinary Scientific GeoConference Surveying Geology and Mining Ecology Management, SGEM : International Multidisciplinary Scientific Geoconference, 2018. - Vol. 18: 18th International Multidisciplinary Scientific Geoconference, SGEM 2018 (2 July 2018 through 8 July 2018, ) Conference code: 142896, Is. 3.1. - P251-258, DOI 10.5593/sgem2018/3.1/S12.033 . -
Аннотация: The empirical orthogonal functions method is widely used for the study of the hydrophysical characteristics in meteorology and oceanography, for example for the analysis of ocean surface currents in the North Carolina and the distribution of horizontal velocities in the Shira Lake. This method is also applied to study the distribution temperatures with depth in the Pacific Ocean and to analyze sea surface temperature in the Western North Atlantic. The empirical orthogonal functions method gives us an optimal modal decomposition of the data and allows us to identify particular modes with relevant physical processors. The empirical orthogonal functions analysis used in this study was performed to measure temperature and vertical velocity in Lake Shira (Southern Siberia, Russia) in the summer of 2014 and 2015. The measurements of currents were recorded using Acoustic Doppler Current Profilers 600 kHz and 1200 kHz at two points. The measurements of temperature were recorded by termistor sensors distributing with depth at ten locations. The first and second empirical orthogonal modes for temperature account for 70-90 % of the total energy. They were used to identify the periods of summer heating and the location of the thermocline. The first mode for surface temperature accounts for about 96 % of the total energy and corresponds to surface temperature gradients. The first mode for vertical velocities accounts for about 10 % of the total energy and the analysis of the corresponding modal coefficient makes it possible to determine the periods when water moves up or down vertically. © SGEM2018 All Rights Reserved.

    Distribution of endemic crustaceans from the lake baikal to the Yenisei River
/ A.

Аннотация: Yenisei River is the main Siberian river, it is one of the seven largest rivers in the world and it is the most high-water river in Russia. It is known that the emergence of large hydraulic structures causes a prolonged, and sometimes irreversible, destabilization of aquatic ecosystems. The construction of Krasnoyarsk hydroelectric power station (HPS) caused global changes in hydrological, hydrochemical and hydrobiological regimes in the Yenisei River. The Yenisei River in the downstream of the HPS does not freeze in winter over 100-300 km from the dam. Hydropower engineering has caused global changes in Yenisei’s zoobenthos, especially in the HPS downstream. The stoneflies and blackflies have almost disappeared from the benthic fauna, the density and number of caddisflies and mayflies species have significantly decreased. Quantitative characteristics of zoobenthos in the area from the dam to the Angara’s estuary have greatly increased: quantity – by more than 2 times, biomass – by 5 times. The growth of indicators is determined, firstly, by the spread of Gammaridae from Lake Baikal through the Angara river upstream of the Yenisei, while their proportion in the total zoobenthos biomass increased by 10 times. This work is devoted to the spatial dynamics of Baikal endemic amphipods in the Yenisei, which spread far beyond the Baikal not only downstream, but also upstream. The results of expedition hydrobiological studies, conducted in 2015-2016 in several zones of the Yenisei River from its head to the mouth, are presented. Throughout the river, Gmelinoides fasciatus quantitatively dominated among the Gammaridae, Philolimnogammarus viridis took the second place. Only in the lower reaches and in the delta of the Yenisei the leading positions were transferred to Pontoporeia affinis-a representative of the estuary-relic complex of organisms. Baikal endemics actively populated the Upper Yenisei section below the Sayano-Shushensky hydroelectric power station, especially in the areas of massive macrophyte distribution. There is a divergence of ecological niches in G. fasciatus and Ph. viridis in the Yenisei: the dominant prefers silty sand-and-shingle biotopes with a calm speed rate; the subdominant tends to prefer stony-pebble bottom washed by a rapid current. Over the past 15 years, the density and proportion of crustaceans in the zoobenthos have increased in the Angara-Podkamennaya Tunguska section. © SGEM2018 All Rights Reserved.

    Flow analysis in closed oval-shaped salt lake based on numerical modeling and field observations in summer
/ T. Iakubailik, L. Kompaniets // International Multidisciplinary Scientific GeoConference Surveying Geology and Mining Ecology Management, SGEM : International Multidisciplinary Scientific Geoconference, 2018. - Vol. 18: 18th International Multidisciplinary Scientific Geoconference, SGEM 2018 (2 July 2018 through 8 July 2018, ) Conference code: 142896, Is. 3.1. - P327-334, DOI 10.5593/sgem2018/3.1/S12.043 . -
Аннотация: A salt stratified Lake Shira has been the subject of extensive research because of its central role in the existence of the Khakassia resort area. The previous research was mainly aimed at water quality issues. The studies of the physical dynamics of Lake Shira relevant to the present work include the general observation of currents on the basis of the field experiments in 2011-2014. Velocity measurements were carried out using Doppler Current Profilers with frequency 600 kHz and 1200 kHz in the bottom track mode in 2012 and at several permanent stations in other years. Temperature measurements were performed using distributed temperature sensors at several stations. In the field observations, internal waves were detected. Three-dimensional primitive equation numerical model GETM is applied to simulate hydrophysical processes in Lake Shira. The model is hydrostatic and Boussinesq. The measured temperature and salinity distribution is taken as the initial data for computations. Computations with time constant wind and the initial horizontally homogeneous and vertically stratified density illustrate the dependence of three dimensional current on the wind strength and direction. The calculations with the variable wind speed show that the termination of the wind leads to the appearance of the internal waves. © SGEM2018 All Rights Reserved.

    Configuration of sources of earth’s magnetic field obtained by solving inverse magnetometry problem
/ V. A. Kochnev // International Multidisciplinary Scientific GeoConference Surveying Geology and Mining Ecology Management, SGEM : International Multidisciplinary Scientific Geoconference, 2018. - Vol. 18: 18th International Multidisciplinary Scientific Geoconference, SGEM 2018 (2 July 2018 through 8 July 2018, ) Conference code: 142901, Is. 6.1. - P553-560, DOI 10.5593/sgem2018/6.1/S28.073 . -
Аннотация: Sources of magnetic field are often approximated by dipoles or current loops, however it this work they are approximated by magnetized prisms instead, which is possible due to equivalency between magnetized objects and currents. Distribution of effective magnetization is then obtained by solving inverse magnetometry problem using the adaptive method of refining the unknown values based on discrepancy between initial values and model values. Z-components of Earth’s magnetic field in IGRF-2005 model in geocentric coordinate system are used as initial values. This allows obtaining the distribution of volumetric currents and magnetic moments for the Earth’s core, which is found to be significantly asymmetric, with four major anomalies, corresponding to surface anomalies: Australian, Canadian, South-Atlantic and Siberian. Work contains additional analysis of the model, initial values and features of the used method in relation to obtained result. Potential source of energy maintaining the currents is suggested, in form of tidal forces, caused by the gravitational influence of the Moon and the Sun. © 2018, International Multidisciplinary Scientific Geoconference.

Kolosova // International Multidisciplinary Scientific GeoConference Surveying Geology and Mining Ecology Management, SGEM : 18 / 18th International Multidisciplinary Scientific Geoconference, SGEM 2018 (2018 ; 02.07 - 08.07 ; Albena). - 2018. - 18DOI 10.5593/sgem2018/2.1/S07.033 . -
Аннотация: Carrying out scientific experiments and field observations requires systematization, coordinated storage and possibility of online analytical processing of primary data to obtain consistent results and to discovery new knowledge. The article presents an approach to building a model-driven system based on the software platform of primary data collection and analysis. An approach to the constructing the control model of the data consolidation system based on the analysis of data description in the context of the stages of scientific research is suggested. It describes the process of formation of the control model and data consolidation system configuration for scientific research via the platform interface. The control model of the system is based on the definition of objects of the area of exploration, their properties and relations between them. The proposed approach is illustrated by an example of the problem of assessing the degree of soil degradation, anthropogenic and technogenic load on the soil using bioluminescent enzymatic analysis. The obtained results are the basis for further analytical and intellectual processing of the accumulated data.

Аннотация: The main task of complex environmental monitoring is evaluating the state of an aquatic system and state prediction of ecosystem links under different levels of water supply, anthropogenic influence and climatic fluctuations. The paper analyzes the inter-annual dynamics of functional activity of bacterio – and phytoplankton of the Krasnoyarsk reservoir depending on abiotic factors (reservoir filling level and temperature conditions). The data have been obtained from series of regular observations during the growing season in the 2000 – 2017. In the work, distribution of concentration of chlorophyll "a" and photosynthetic activity of the phytoplankton, production characteristics of bacterioplankton and biochemical oxygen demand (BOD5) are presented. The analysis is carried out in the model-driven system of support of hydrobiological studies of the Krasnoyarsk reservoir by the method of k-means. Systematization of accumulated data of scientific research has become a basis for a sequence of long-term investigations, a comparative analysis of data from related studies and data analysis.

    Characteristics of the zoobenthos communities in the mountain rivers of the yenisei basin
/ A. Andrianova // International Multidisciplinary Scientific GeoConference Surveying Geology and Mining Ecology Management, SGEM : International Multidisciplinary Scientific Geoconference, 2019. - Vol. 19: 19th International Multidisciplinary Scientific Geoconference, SGEM 2019 (30 June 2019 through 6 July 2019, ) Conference code: 150487, Is. 3.1. - P81-88, DOI 10.5593/sgem2019/3.1/S12.011 . -
Аннотация: In 2015, zoobenthos communities in the river Yenisei (upper and middle course) and in its tributaries (rivers Abakan, Mana, Kan, Agul, Kungus) was studied. All watercourses are mountain rivers, in the bottom fauna of which lithoreophilic organisms predominate, populating stony soils in a large current, at low water temperatures and favorable oxygen conditions. In zoobenthos, 231 species of macroinvertebrates were found, widely distributed in the Palaearctic and Holarctic regions. Dominant complexes were characterized by variability with the distance from river sources. In the river Yenisei benthos species composition expanded from the upstream (48 species) to the lower reaches (69 species). In the upper reaches of the Yenisei (area 1 - from the Kyzyl city to the city of Shagonar) the core of the benthic communities was represented by mayflies, caddis flies and chironomids. Downstream (area 2 - from the dam of the Mainskaya hydro power station to the Abakan city) the determining factor for the formation of the zoobenthos structure was the abundance of phytocenoses, where the Baikalian amphipods Gmelinoides fasciatus dominated. In the zoobenthos of the Middle Yenisei (area 3 - from the dam of the Krasnoyarsk Hydroelectric Power Station to the mouth of the Angara River), the chironomids took the leading positions. The quantitative distribution of the bottom fauna in the Yenisei was characterized by low values in the upper reaches (612 ind./m2and 4.2 g/m2) and high values in area 2 (5.5 thousand ind./m2and 19.5 g/m2). In the middle course of the Yenisei in area 3, the density of benthic communities (2.8 thousand ind./m2and 10.5 g/m2) is quite consistent with our earlier studies in the beginning of 2000s - 3.5 thousand ind./m2and 10.8 g/m2. In the tributaries of the Yenisei, the benthos species composition is more diverse than in the Yenisei; maximum values were in the rivers Mana and Kan (110 and 103 species, respectively). Bottom communities are represented predominantly by chironomids and mayflies, in the river Kan caddis flies complemented the quantity. The quantitative distribution of the bottom fauna in the tributaries of the Yenisei was heterogeneous. The smallest abundance (577 ind./m2) was recorded in the river Abakan, that belongs to the basin of the Upper Yenisei. The maximum abundance (2.8 thousand ind./m2) was found in the river Mana flowing into the Yenisei above Krasnoyarsk (basin of the Middle Yenisei). In the Kan River, which flows into the Yenisei below Krasnoyarsk, the abundance of benthos is comparable to its tributaries Agul and Kungus (1.2-1.9 thousand ind./m2). The distribution of biomass in the studied water streams depended on the taxonomic structure of benthic communities. The maximum values (10.1 and 12.3 g/m2) were found in the rivers of the Middle Yenisei - Man and Kan, and are associated with the dominance of caddis flies. In the rivers Abakan, Agul and Kungus biomass on average did not exceed 8 g/m2, while the contribution of stoneflies is higher than in other rivers. © SGEM2019.

    Development of an algorithm for assessing the underlying surface in the areas of felling on heat maps based on remote sensing data
/ A. V. Dergunov [et al.] // International Multidisciplinary Scientific GeoConference Surveying Geology and Mining Ecology Management, SGEM : International Multidisciplinary Scientific Geoconference, 2019. - Vol. 19: 19th International Multidisciplinary Scientific Geoconference, SGEM 2019 (30 June 2019 through 6 July 2019, ) Conference code: 150486, Is. 2.2. - P517-524, DOI 10.5593/sgem2019/2.2/S10.063 . -
Аннотация: Response to anthropogenic disturbances, recorded according to remote sensing of the Earth, has a long-term manifestation not only in the spectral characteristics of the channels of visible and near infrared ranges of satellite imagery, but also in the study of the temperature field. The paper deals with the local excess temperature of the underlying surface in the areas of cutting the territory of the Angara region, compared with the background values identified by satellite data Landsat 5 and 8 for the seventeen-year period. Estimates of the relative difference in the temperature of the underlying surface of the cutting area in comparison with the average background values are obtained. To this end, a number of software products to automate the archiving and conversion of satellite information has been developed. These software products are designed for calculation of the radio-brightness temperature of the underlying surface of disturbed and undisturbed areas of forest vegetation in the pre-selected areas of the territory. They are also used to average the obtained data of radio-brightness temperature and to calculate the difference between the average values of the radio-brightness temperature of the underlying surface of the disturbed areas relative to the undisturbed, that is, the background. This approach can significantly reduce the processing time of a large amount of information and optimize the amount of data storage. Separately, the study area was analyzed according to the NDVI vegetation index. The data obtained demonstrate a high rate of recovery of grass cover and grass-shrub layer immediately after damage to forest vegetation. It is shown that during the considered period of time (17 years) the value of excess temperature decreases, which is determined by the processes of vegetation restoration, including stand on felling. It is established that the increased temperatures of the underlying surface in the place of cuttings are remained for at least 15 years, and the temperature increase over the background values in the conditions of the observed successional processes is not less than 10%. As a limiting factor in the restoration of the temperature background of the underlying surface, fires can act. © SGEM2019. All Rights Reserved.

Аннотация: The experience of introduction of GIS technologies in the regional agriculture system of the Krasnoyarsk Territory is given. The digital model of Experimental Agricultural Enterprise “Minino” situated near Krasnoyarsk city is formed using geoinformation technologies, remote sensing data and methods, web mapping software tools. The resulting digital model contains relevant information about the agricultural fields, varieties, crops, soil, granulometric composition, soil-forming rocks, conditions of occurrence in relief. Multispectral satellite images have been selected for the territory under consideration, allowing to effectively solve the problems of agricultural monitoring. A series of technological, digital maps and cartograms have been created, which concentrate information on crop rotations and cultivated crops. In general, a multi-layer electronic map of the agricultural enterprise was created, tabular information of the database of the history of fields was introduced, taking into account all the performed agro technical measures. Access to the prepared thematic maps is carried out on the basis of web-mapping tools. The developed software provides the ability to visualize geospatial data in a normal web browser or by standard web mapping services in desktop software such as MapInfo, QGIS, ArcGIS, etc. Geospatial database of soil information is the first step of digitalization of the system of agriculture of the Krasnoyarsk territory. © SGEM2019.

    Analysis of vortex structure in a shallow stratified lake

Gavrilova // International Multidisciplinary Scientific GeoConference Surveying Geology and Mining Ecology Management, SGEM : International Multidisciplinary Scientific Geoconference, 2019. - Vol. 19: 19th International Multidisciplinary Scientific Geoconference, SGEM 2019 (30 June 2019 through 6 July 2019, ) Conference code: 150487, Is. 3.1. - P41-48, DOI 10.5593/sgem2019/3.1/S12.006 . -
Аннотация: In the summer period of 2018 satellite-tracked quasi-lagrangian drifter was launched in saline stratified Lake Shira (Republic of Khakassia, Russia). The analysis of obtained data was revealed a mesoscale vortex structure in the lake. At the same time, measurements of the current velocity were carried out at several points in the lake using an Acoustic Doppler Current Profiler (ADCP). The reliability of the data obtained using the quasi-lagrangian drifter is confirmed by a comparison with the data for the current velocity and for the direction and speed of the wind. The horizontal velocity was analyzed using complex empirical orthogonal functions. The hodograph of the first temporal coefficient shows the elliptical structure of the current. This effect may be due to the strong variability of wind on the lake during the summer period or to the vortex structure of wind stress. To clarify the origin and distribution of the mesoscale eddies (vortices) in Lake Shira, it is necessary to conduct a study with a large number of drifters. © SGEM2019.

Аннотация: The results of research and development devoted to the creation of information and computing support for the system of operational satellite monitoring in the regional center for remote sensing of the Earth in Krasnoyarsk are considered. The initial information comes from its own satellite reception complex of Krasnoyarsk Science Center and via Internet channels from Roscosmos geoportal. The created software package provides a full cycle of operations with satellite data, including-their reception and pre-processing, placement in the archive, conversion and visualization services with the help of a specialized geoinformation web system to work with the catalog of satellite data. Special information content of this system has also been created, including a collection of basic cartographic substrates, additional cartographic data layers. A set of tools for operational analysis of available information, including tools for working with different combinations of layers of multispectral images, has been implemented.
