The state of plant communities in areas located in the Tersko-Sulak lowland was studied by assessing phytocenotic indicators: the structure of vegetation cover, projective cover, species diversity, species abundance and elevated production, as well as automated decoding methods. There are almost no virgin soils and natural phytocenoses here; all of them have been transformed into agrocenoses (irrigated arable lands and hayfields, rice-trees and pastures). The long-term impact on pasture ecosystems of natural and anthropogenic factors leads to significant changes in the indigenous communities of this region. Phytocenoses are formed mainly by dry-steppe types of cereals with the participation of feather grass, forbs and ephemera, a semi-desert haloxerophytic shrub - Taurida wormwood. At the base of the grass stand is common coastal wormwood and Taurida wormwood - species resistant to anthropogenic influences. Anthropogenic impacts have led to a decrease in the number of species of feed-rich grain crops and a decrease in the overall productivity of pastures. Plant communities in all areas are littered with ruderal species. The seasonal dynamics of the land cover of the sites was estimated by the methods of automatic decoding of satellite images of the Landsat8 OLI series satellite for 2015, dated by the periods: spring - May 20, summer - July 23, autumn - October 20. Satellite imagery data obtained by Landsat satellite with a resolution in the multispectral image of 30 m per pixel, and in the panchromatic image - 10 m per pixel, which correspond to the requirements for satellite imagery to assess the dynamics of soil and vegetation cover. Lower resolution data, for example, NDVI MODIS, does not provide a reliable reflection of the state of soil and vegetation cover under arid conditions. In this regard, remote sensing data obtained from the Internet resource https://earthexplorer.usgs.gov/ was used.

The article deals with A. Bushkovsky’s novel Rymba that goes beyond the topics typical of Russian North prose. Rather than limiting himself to admiring nature and Russian character, the author portrays the northern Russian village of Rymba in the larger context of the country’s mentality, history, mythology, and gender politics. In the novel, myth clashes with reality, history with the present day, and an individual with the state. The critic draws a comparison between the novel and the traditions of village prose and Russian North prose. In particular, Bushkovsky’s Rymba is discussed alongside V. Rasputin’s Farewell to Matyora [ Proshchanie s Matyoroy ] and R. Senchin’s The Flood Zone [ Zona zatopleniya ]. The novel’s central question is: what keeps the Russian world afloat? Depicting the Christian faith as such a bulwark, Bushkovsky links atheism with the social and spiritual roles played by contemporary men and women. The critic argues, however, that the reliance on Christianity in the novel verges on an affectation. The book’s main symbol is a drowning hawk: it perishes despite people’s efforts to save it.

O presente trabalho visa compreender a natureza e suas ações no cotidiano urbano de Parnaíba, cidade do litoral do Piauí, nos anos 1970. Buscamos em meio às notícias dos periódicos locais o retrato das enchentes ocorridas no recorte em questão, bem como suas ações e problemas causados para os munícipes. Com isso, fazem parte do nosso corpus documental três jornais que circulavam em Parnaíba naqueles anos, Folha do Litoral, Norte do Piauí e Jornal Inovação. Para além, foram utilizadas ainda o anuário Almanaque da Parnaíba e o livro de memórias Cada rua, uma história, do jornalista e escritor Caio Passos (1982).*This paper aims to understand the nature and its actions in the urban daily life of Parnaíba, a seaside town in the state of Piauí, in the 1970’s. We searched through news from the local periodicals the picture of floods that occurred in the chosen period, as well as its actions and the problems caused to the citizens. Thus, three newspapers that circulated in Parnaíba during those years, Folha do Litoral, Norte do Piauí and Jornal Inovação compose our documentary corpus. In addition, the annual Almanaque da Parnaíba and the memory book Cada rua, uma história, both written by the journalist and writer Caio Passos (1982), were also used.Keywords: Parnaíba; nature; the 1970’s.

Abstract. This paper presents a new Multiview Stereo Pipeline (MVS), called CARS, dedicated to satellite imagery. This pipeline is intended for massive Digital Surface Model (DSM) production and has therefore been designed to maximize scalability robustness and performance. Those two properties have driven the design of the workflow as well as the choice of algorithms and parameter trends, making our pipeline unique with respect to existing solutions in literature. This paper intends to serve as a reference paper for the pipeline implementation, and therefore provides a detailed description of algorithms and workflow. It also demonstrates the pipeline robustness and stability in several use cases, and compares its accuracy with the state-of-the-art pipelines on a reference dataset.

This article discusses the task of developing an urban planning methodology for assessing the degree of destruction of residential areas aff ected by hostilities in Syrian cities. This methodology will be the basis for the theoretical substantiation of the process of restoration the destroyed residential areas of the cities and their functional planning organization in the context of ongoing military confl icts. The research is based on the methodology for assessing the degree of destruction of buildings presented in GOST R 42.2.01-20141 « Civil defense. Assessment of the state of potentially dangerous facilities, defense and security facilities under the infl uence of damaging factors of conventional weapons» .The state of the buildings destruction is determined using satellite imagery as well as fi eld tests. The parameters of the damaging factors are determined analytically. The developed methodology makes it possible to determine the degree of destruction of residential areas within the radius of destruction formed by the excess pressure of the blast wave and the explosives used and to assess the suitability for recovery in the context of continued hostilities. On the basis of the established degree of destruction of residential areas, a scheme of urban planning zoning of the residential area of Homs was made.

The Impact

In the conditions of scientific and technological progress, the relationship of society with nature has become much more complicated. Man got the opportunity to influence the course of natural processes, started to use almost all available renewable and non-renewable natural resources, and as a result, began to pollute and destroy the environment. Specialists of the State Ecological Academy of Postgraduate Education and Management, within the framework of the scientific work “Development of the methodological basis of orthotransformed satellite imagery application in environmental assessment”, solved an actual scientific and applied task, which is to form a methodological basis for the use of orthotransformed satellite imagery to create information services for environmental monitoring of objects of critical infrastructure and expanding the capacity of the National Center of the provision of central executive authorities of information about the results of environmental monitoring based on space systems data through the development of methods of using orthotransformated satellite imagery for the assessment of the environmental state. The possibilities of using multispectral space images to assess the state of the environment are determined and the necessary software for this is given. Based on the classification algorithm of enterprises and objects of critical infrastructure of Ukraine, a GIS-compatible database of objects of critical infrastructure of Ukraine classified by their environmental impact was developed and a methodology for using orthotransformed satellite imagery was developed to assess the impact of the corresponding categories of critical infrastructure facilities of Ukraine on the state of the environment. During creating the ideology of geographic information systems, the requirements for technical means on which the service should be deployed, the procedure for maintaining, filling and updating the database of objects of critical infrastructure of Ukraine, the mechanism and procedure for visualizing impact assessments of all objects of the developed base based on GIS-systems.
