Such a constellation could provide operational monitoring of fast-moving atmospheric cyclones, measuring directly the parameters of storm waves (altitude and orbital velocity)—which would replace the existing constellation of microwave scatterometers, providing operational monitoring of the World Ocean surface in the 3 H (H—altitude of the satellite’s orbit) field of view with a resolution of about 10 km—but with calibration of the received images by wind speed and direction, which leads to huge errors when trying to introduce altitude calibration in the Small spacecraft have many advantages over large satellites. For example, they are relatively inexpensive to build, take minimal time from design to launch, are easily modified to solve a specific problem, and create less radio interference. The approach under consideration consists in redistribution of tasks to be solved between the constellation of satellites in orbit. High orbiting navigation satellites, for example, can be used as transmitter carriers (of the illumination of the surface) that use the necessary broadband signal with acceptable periodicity. Receivers of reflected signals are placed on board small spacecraft, and at formation of wide-band radar image of sea surface with necessary resolution ∼10 m (that only on order exceeds acceptable on small spacecraft size of receiving antennas)—in flight direction is necessary to use synthesized aperture of receiving antenna.

As a result of modern reforms, Russia has become a leading player in the foreign food market. However, these positive developments take place against the background of a process of deepening regional differences in the productivity of the agricultural sector. The aim of the study is a comparative analysis of the dynamics of the withdrawal from circulation of sown areas in the Kirov province during the crisis of the 1990s. and post-crisis period 2000–2020. The analysis of spatio-temporal dynamics of the withdrawal from circulation and restoration of croplands was carried out by remote sensing methods for three agro-climatic zones and the main types of soils in the Kirov province. The main resource of the region is soddy-podzolic soils, which accounted for more than 77 % of the cropland in 1990 and about 70 % in 2020. The reduction in the area of cropland with this type of soil reached 90 % in the northern and 80 % in the central and southern zones, regardless of their differences in heat supply. Crisis period 1990–2000 characterized by the highest rate of withdrawal of agricultural land from circulation. In the post-crisis period, the reduction in sown areas only continued. Against this background, there is an extremely slight recovery of cropland (about 5 % of the 1990 level). There are natural differences in the restoration of sown areas in agro-climatic zones and by soil types, but they are poorly reflected in the overall negative dynamics of cropland, due to the low agro-climatic potential of the entire Kirov province.","PeriodicalId":31498,"journal":{"name":"InterCarto InterGIS","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69899501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From this it follows that in order to draw up recommendations on forest reclamation measures aimed at increasing the durability of forest plantations, it is necessary to use the available remote sensing data and modern GIS technologies when examining protective forest plantations. The use of modern technologies will allow for a more qualitative assessment of the state of forest plantations in the Volgograd region. The use of the free desktop geographic information system QGIS in research demonstrates a number of possibilities, in particular, deciphering the current state and conducting digital inventory mapping of protective forest plantations based on GIS technologies and aerospace methods. Subsequently, the obtained data will be applied in the development of methods and principles that are scientifically substantiated and aimed at the rational use of resources and the regulation of anthropogenic impacts on the agroforest landscapes of the region. The study was carried out in the southern part of the Ilovlinsky District of the Volgograd region, located in the subzone of chestnut soils on the Kachalino test site. As a result of the study, the use of QGIS made it possible to decipher protective forest plantations in order to determine their spatial distribution, quantity, species and structural composition. On the laid out sites, the main reference schemes of rock mixing were compiled and key signs of protective forest belts were identified during interpretation. The mapping of the forest fund was carried out on the basis of data obtained in the course of visual and instrumental interpretation. The results obtained will become the basis for the development of a regional agroforestry reclamation geoinformation system necessary for updating existing forest maps, monitoring the state of forest plantations and planning various forest management activities aimed at the effective management of the agroforestry fund of the Volgograd region.","PeriodicalId":31498,"journal":{"name":"InterCarto InterGIS","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69899523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The initial data for calculations are arrays generated by the program for processing aerial photographs obtained with drones in photogrammetry mode. The algorithmic basis of the tool is the well-known geoinformation tool named Cut & Fill, used in conjunction with a database on the location and geometry of a large number of sections of the western coast of Crimea. The sequence of operations involves sampling from two or more arrays of points according to a given spatial location, performing vertical alignment with use the number of ground control points, performing interpolation into a regular grid of the size accepted for each section, calculations and presenting the results in tabular and graphical form. All the results obtained are saved for reuse and, in addition, their graphical analysis for spatial and vertical alignment is possible. It is also possible to build vertical sections on any row or column of a regular grid.
