The presented article analyzes the topical issue of using geographic information systems in monitoring agricultural land in the Republic of Uzbekistan. Research methodology - analysis of scientific literature on a given problem, as well as practical domestic experience. The scientific novelty of the article lies in the demonstration of modern and relevant data on the land monitoring system within the framework of the agricultural industry on a specific example of a country - the Republic of Uzbekistan. As the main conclusions and results of the article, we can highlight the fact that Most of the economy of Uzbekistan is based on the development of the agricultural sector. In the field of agricultural production, high technologies are actively used here, namely, geographic information systems, which allow real-time collection of data on the area and other characteristics of agricultural land. So, systems based on GIS technologies have been used in the field of agricultural production since 2005. They collect and automatically process information on the turnover of agricultural land. As world practice shows, there are broad prospects for expanding the functionality of such systems. Thus, an integrated monitoring system allows you to plan the harvest and predict the amount of necessary fertilizers to be applied to the soil, analyze the effectiveness of agricultural work, etc. The integrated monitoring system is based on a map linking information about the location, area and boundaries of agricultural land. The results of the article are of theoretical and practical importance for modern science and can be recommended as citation in scientific papers.

Accelerated water erosion is the major problem of agricultural soils all over the world and also in the Slovak Republic. Accelerated erosion occurs in 55 % of agricultural land. It belongs to physical degradation of fertile land, and the whole process is irreversible. Therefore, it is very important to localize the presence of accelerated erosion and apply the basic principles of soil erosion control. Geographic information systems (GIS) are an effective tool for various environmental analyses, so it can also be succesfully used for determination of potential erosion intensity. The aim of this work was to create a map of domain areas that describes potential water erosion. As an area of interest the cadastral territory of Topolcianky in the Slovak Republic was selected. For this purpose the GIS software Arcview from ESRI was used. Water erosion process was modelled by universal soil loss equation (USLE) which computes an average annual soil loss. The limit values of acceptable intensity of soil loss are defined in the Collection of Laws of the Slovak Republic (Act No 220/2004 Coll). The final result of this work is a map that divides the domain area according to potential annual soil loss into several categories. In this case the domain area was divided into four categories. The first category, named slightly threatened soil, had 620,05 ha of agricultural land (77,48 per cent of the total agricultural land of domain area). The second category, called averagely threatened soil, had 106,56 (13,32 per cent of the total agricultural land). The third category (intensively threatened soil) had 70,91 ha (8,86 per cent of the total agricultural land) and finally the fourth category (very intensively threatened soil) had 2,74 ha (0,34 per cent of the total agricultural land).

Remote Sensing Methods

Purpose: determination and analysis of the relevance of the geographic information systems (GIS) use in assessing the degradation degree of agricultural land as a result of erosion processes. Discussion: the article is devoted to the problem of studying modern methods for assessing the state of agricultural lands subject to negative processes. Water and wind erosion (deflation) are the most widespread and harmful types of soil degradation. So, water erosion (19.32 % of the territory of the surveyed lands) is the most widespread on the agricultural lands of the Russian Federation. The main tool for identifying soil degradation processes is the monitoring system, and the most effective and promising method for assessing the degree of land degradation is the Earth remote sensing (ERS) method. All of the above, together with reclamation techniques (land reclamation, field-protective afforestation, etc.) is a means of preserving and improving the quality of agricultural land resources, including those prone to erosion and deflation. The main advantages and examples of detecting soil degradation using remote sensing data are presented. The analysis of information on the spread of negative processes on the lands of the Russian Federation is carried out. Based on the analysis of the current state of land erosion, it becomes urgently necessary to carry out a set of measures to stabilize and restore the fertility of agricultural land. Conclusions: objective and reliable data on the state of soil erosion can be obtained only by combining ground (agrochemical surveys) and remote sensing methods of the Earth. Since the assessment of the degree and territorial distribution of soil degradation types can be carried out with high reliability using aerospace photography materials and ground-based research data, it is necessary to use remote sensing methods of the Earth and geographic information systems more widely, in addition to field surveys.

The Serbian Armed Forces support represents a part of the military activity aimed at creating conditions for the execution of missions and tasks. For successful support, it is necessary to establish the cooperation with relevant institutions of the Republic of Serbia. The conceptual definition of the geo-topographic support has been researched in the context of previous and current regulations, which have shown that the achievements of information and communications technology have influenced not only the development of the geographic information systems, but also directly the definition of this concept. The importance of the geographic information systems in the collection, processing, analysis and use of geospatial data has also determined the contents of the geo-topographic support. The continuous development of the geographic information systems in the direction of establishing a service-oriented approach to the distribution and use of geospatial data, will directly affect the future improvement of the content of the geo-topographic support. Such a process is accompanied by the establishment of the geo-topographic support principle, which should enable the construction and maintenance of a stable structure, in order to successfully carry out the assigned missions and tasks of the Serbian Armed Forces.

Geoinformation technologies are applied, without exaggeration, in all spheres of human activity, and the geological industry is no exception. Geoinformation systems in geology help to solve a number of practical problems. Geologists specializing in mineral exploration use a variety of data sets to search for new, cost-effective deposits, from geological maps, hyperspectral aerial photographs and multispectral satellite imagery to databases of various formats. The geographic information system is an ideal platform for combining such heterogeneous information and its subsequent analysis. The article describes the experience of the national mining company of the Republic of Azerbaijan CJSC AzerGold in the use of geographic information systems in the exploration of non-ferrous metal deposits using the example of the development of the Filizchay and Aghyokhush deposits. The authors considered production problems, described the problems that arise at the stage of exploration and proposed methods for solving them, the need for the integrated use of information systems in exploration when searching for deposits of non-ferrous metals is noted. A database structure has been developed for the purpose of geological exploration of non-ferrous metal ores, including sections such as topography, geochemistry, geophysics, structural geology. The structure of geoinformation support for geological exploration of non-ferrous metal ores is proposed, which combines the functionality of geographic information systems (GIS) and mining geological information systems (MGIS). The stages of geoinformation processing of initial data are illustrated, on the basis of which a geological exploration strategy was formed at the Filizchay pyrite-polymetallic deposit, and then the optimal places and number of wells, coordinates, directions and angles of incidence of wells were determined quickly and with high accuracy, as well as the resource potential was specified. The role of interpolation methods in determining the primary exploration wells in the exploration of the Agyokhush gold deposit is disclosed.
