Applying the combination of GIS tools with upgraded structural and morphological methods for studying neotectonics

Structural and geomorphological methods are often applied to the search for small oil-producing structures. Morphometric analysis of digital elevation models has proved to be the most informative one. Morphometric surfaces can be used to evaluate the direction and amplitude of vertical movements, to outline local and regional neotectonic structures and assess their petroleum saturation. This paper shows how to enhance the traditional morphometric analysis with GIS (geographic information systems) tools. A manifold increase in the efficiency of morphometric analysis takes it to a qualitatively new level. Setting specific parameters for some geoprocessing tools (for example, stream network tools) can be very important when studying local structures in small areas. In case of large territories, the output result is almost independent of the calculation errors. The improved technique proposed in this paper was tested on a large territory located in the Volga region. As a result, high-order morphometric surfaces were obtained, which was not possible before. In addition, a statistically significant relationship was discovered between morphometric surfaces and distribution of oil deposits, which can be considered a reliable prospecting indicator in the Volga-Ural petroleum province. Keywords: neotectonics; structural and morphological methods; geoinformation systems; hydrocarbon potential assessment.

Complex Analysis of Data from Agrochemical and Soil-Erosion Monitoring Using Geoinformation Systems

The article describes a comprehensive analysis of agrochemical and soil erosion monitoring data, using the example of the Alekseevsky district of the Belgorod region with the use of a geoinformation system. The GIS automatically generates tables with data grouped by various characteristics: soil type, degree of erosion, slope steepness and exposure. The content of mobile forms of phosphorus and potassium, organic matter, and the level of soil acidity in the context of the district in areas with different exposures, the degree of erosion and the steepness of the slope was analyzed. The most productive soils are located on the plain, followed by the slopes of the northern exposure, neutral, then southern. Erosion processes occur more strongly mainly on the slopes of the southern exposure, and the northern slopes are characterized by humidity. Down the slope, the nutrient content decreases, the level of soil acidity increases.

Creepex as a parameter of seismo-geodynamic studies based on geo-information systems

The GIS-EEDB (the Expert Earthquake Database) and GIS-ENDDB (the Earth’s Natural Disasters DataBase) geoinformation systems implement methods for spatial-temporal analysis of both classical and new characteristics of the seismogeodynamic process. One of the new characteristics is a normalized creepex parameter that can be used in the statistical approach to studying of seismicity to assess a relative contribution of “soft” (creep) and “hard” (explosion) movements to the overall process of focal radiation. In this paper, the following modifications of the creepex parameter are proposed and compared: 1) Cr0 Cr0_world and CrN CrN world as the result of reducing the parameters Cr0 and CrN of each event to the world average values of the creepex, obtained from the polynomial dependence of Cri_world (i = 0, N) on MS_world where Cri_world are calculated based on the world average estimates of Ms_world and mb_world at uniform intervals of the seismic moment (NEIC catalog), 2) Cr_bji as the result of reducing CrN of each event to CrN_bji i.e. to the average for the studied in this work BJI catalog creepex values obtained from the polygonal trend CrN (MS) of all the catalog events. The advantage of using the creepex parameter, reduced to the trend of averaging the magnitudes of the catalog in question, is revealed, since the smallest linear dependence of the creepex on the magnitude is achieved (in comparison with the classical and normalized creepex) and the symmetry in the maximum amplitude of the deviation of the parameter relative to zero is preserved. Examples of the application of the compared parameters in specific seismic-geodynamic studies of aftershock processes of the Molucca and Simushir earthquakes also demonstrate the advantage of the parameter Cr_bji n the observed correspondence of the variations of the latter to the known physical processes in the focal zone of the Kashmir event, studied by the seismic-geodynamic methods of the GIS-EEDB geographical information system.

Land use analysis of Lake Khanka basin using remote sensing data

The paper presents results of the analysis of the land use map compiled for transboundary Lake Khanka Basin using remote sensing data and geoinformation systems. The map reflects the distribution of 12 land categories in Lake Khanka basin in 2017 (arable land, abandoned arable land, paddy field, abandoned paddy field, shrubs and sparse growth, forest land, open pit, settlements, meadows and pastures, wet meadows and marshes, water bodies, forest cuttings and fire sites). The data of land use structure in the whole Lake’s watershed, in its Russian and Chinese parts are given. Data on the distribution of different land categories in the administrative territories of the rank of districts (Russia) and counties (China) are also presented. The analysis of land use structure showed that about 50 % of the Chinese part of the basin is covered by anthropogenically transformed natural complexes. The share of such lands in the territory of Russia amounts to 28 %. Agriculture is the most important factor in the change of natural complexes in Lake Khanka basin. Before early 1990s, the area of farmland had increased in the basin on both sides of the border, after that there was a significant reduction in cultivated lands, which had lasted for 10 years in the territory of China and for 20 years in Russia. Over the past decade, the area of cultivated areas in the basin and adjacent territories has extended again, which indicates an increase of anthropogenic impact and requires serious attention to monitoring of the ecological state of lands in the basin.

VECTORIZATION OF MAPS OF RURAL SETTLEMENTS IN THE PREPARATION OF LOGISTICS WITH HELP OF GEOINFORMATION TECHNOLOGIES

The article is devoted to the traditional sphere of application of Geoinformation systems – logistics and use of Geoinformation technologies in the process of preparation of future logisticians on the basis of the offered technique of carrying out laboratory employment with use of vectorization of a rural settlement map. It is claimed that Geoinformation technologies allow to present statistical information on maps and provide tools for processing spatial statistical information with taking into account its qualitative and quantitative properties. The reasons of efficiency of the mechanism of the decision of a logistic problem are defined, some widespread ways of optimization of logistic activity on the basis of the geographical approach are considered and the directions of its optimization are established. The main professionally necessary tasks that represent a valuable part of cartographic literacy of future professionals in the field of logistics are highlighted. Due to the priority of development and detailing the maps of urban settlements, there is a decrease in attention to rural and remoted areas, which, to some extent, creates some inconvenience in designing transport routes to the necessary points of location. The sequence of laboratory work on vectorization of the selected part of the map of the rural settlement is offered. Comparing it with the modes "Satellite" and "Map" and adhering to the selected fixed scale, additional graphic prompts are applied. This work is performed in the training of specialists in the specialty 015.38 Professional Education (Transport) at Ternopil Volodymyr Hnatiuk National Pedagogical

Assessment of the Gross Potential of Local Waste Based on Geoinformation Systems for Bioenergy Production

This article analyzes the gross potential of local hydrocarbon waste and biomass using the example of the Republic of Uzbekistan with the aim of producing bioenergy. To calculate the raw material potential, we used official and reference data on the production and consumption of fuel, fertilizers and the formation of organic waste, the accumulation of municipal solid waste (MSW), the amount of saline land where halophytic plantations can be created, which can be considered as biomass. Based on the collected data, mathematical operations and calculations of the potential of biogas technology were performed. A block diagram has been developed that describes the steps of a Geo Information Systems (GIS) map. GIS maps have been created that give a visual representation of the spatial distribution of the gross potential of various types of waste in the regions of the republic and can serve as a tool in planning the distribution of biogas technology.
