Analysis of Seasonal Changes of Zenith Tropospheric Delay Components Determined by Data of Two Pairs of Aerological and GNSS Stations
Authors B. Kladochnyi, F. Zablotskyi and O. SerantSUMMARYIt is known that the tropospheric delay is one of the most important factors that reduce GNSS measurements accuracy. The aim of the work is to analyze the change of both hydrostatic and wet components of zenith tropospheric delay. Today, zenith tropospheric delay components are determined mainly in two ways. The hydrostatic component determined by using analytical models, such as Saastamoinen model. The wet component of ZTD is obtained from GNSS measurements using simulated value of hydrostatic component. The study evaluated the accuracy of the both hydrostatic and wet components of ZTD according to sounding data. For this, two pairs of aerological and GNSS reference stations was selected. First pair of stations is Praha-Libus aerological station and GOPE GNSS reference station, which located in Czech Republic. The second pair is Legionowo aerological station and GOPE GNSS reference station, located in Poland.

Danube Loess Magnetostratigraphy: a Perspective from Ukraine
Authors D. Hlavatskyi, V. Bakhmutov, Yu. Veklych, V. Shpyra and Ie. PoliachenkoSUMMARYA first palaeomagnetic study has been carried out on a new section with a potential lower boundary interval for the Quaternary, Dolynske 3 (Lower Danube, southern Ukraine). Recently, the Matuyama–Brunhes boundary (at 780 ka) was detected in the adjacent section of Dolynske 2. The current study focuses on the hydromorphic clays and pedosediments of the Bogdanivka to Kryzhanivka units (S13–S8). Samples from the Upper Bogdanivka (S11) and Upper Berezan (L9L1) subunits show a clearly defined reversed polarity related to the Matuyama chron; some samples from other layers were uninformative due to hydromorphic features and were rejected from the interpretation. Given the unsuitability of hydromorphic palaeosols and loesses for magnetostratigraphic studies, the determination of the Gauss–Matuyama boundary requires additional, including methodological, research on other sections of Ukraine. The stratigraphic completeness of the composite Dolynske section, its geomorphological location within the Pliocene Danube terraces and convenient geographical setting allow offering it for study as a reference section for the loess/soil formation in the Lower Danube basin. Furthermore, tentative stratigraphic correlations of loess-palaeosol sequences in south-eastern Europe require revision and adaptation in view of new magnetic data from the more complete Ukrainian loess sequences.

Erosion Processes of Mountain Tourist Trails in the Carpathian National Nature Park (Ukrainian Carpathians)
Authors V. Brusak, I. Hnatiak and V. ShtuhlynetsSUMMARYThe tourist trails of Skybovi Gorgany and Chornohora (Ukrainian Carpathians) are analyzed as well as different stages and degrees of trails degression are revealed. Erosion processes evolve on the V stage of recreational degression. It is established that tourist trails differ in the general condition and degrees of recreational degression and the length of the sections with the manifestation of erosion processes. Such diversity depends on the relation to the main elements of the relief, geological substrate, soil and plant cover and the amount of recreational load. Erosion processes are the most appreciable on the tourist trail “to Hoverla mountain” and “Dovbush trail” due to excessive recreational load. Finally, the authors propose organizational, managerial, and engineering activities for improving the condition of the trail.

Study of Coordinates Determination Accuracy Using GNSS RTK Technology by Receivers STONEX S900 and S700
Authors A. Vivat, A. Tserklevych, L. Poliakovska, N. Nazarchuk and O. HrabovyiSUMMARYGNSS (Global Navigation Satellite Systems) technology for determining coordinates has significant advantages over other geodetic methods. This is globality, all-weather, automation. The main disadvantage of GNSS is the dependence on the openness of the horizon for the visibility of satellites. The improvement of GNSS is, for example, the “Tilt” technology ( Luo at. al., 2018 ) - tilt sensors that bring the inclined receiver to a vertical line with an error of 2 – 5 cm depending on the angle of inclination. AGNSS technology is the transmission of corrections through a satellite channel when communication with the base station is lost.” The new “IMU” technology is short-term positioning in space without satellites. Technology “PPP” ( Mulic at. al, 2013 ) - increasing the accuracy of autonomous position determination by introducing corrections to disturbing factors (orbit, atmosphere, additional reflection). The most accurate way to determine the position on the earth’s surface using the GNSS method is the static method with an error of 1–2 mm. The RTK “Real Time Kinematic” method is very relevant today and is often used by surveyors, it provides high accuracy, quality and speed of coordinate determination. Today, GNSS technologies are more actively used by geodetic production and have practically replaced electronic tacheometry in topographic surveying. In our opinion, the “Tilt” technology can increase the accuracy of shooting points when the horizon is significantly closed for GNSS topographic surveying in RTK mode. The instruction on topographic surveying regulates the error for the largest scale of 5 cm. Increasing the number of satellites and satellite constellations should increase the accuracy and reliability of determining the coordinates in the RTK mode. In 2011, we conducted a similar study at the landfill in Berezhany ( Vivat, 2011 ). In the future, technologies will probably be developed that will increase the accuracy of determining coordinates in difficult conditions with a closed horizon. Therefore, such studies are relevant. In 2022, we proposed a synchronous RTK method ( Vivat at. al., 2021 , 2022 ) using two rover receivers to compensate for systematic errors.

Estimation of Zenith Tropospheric Delays Based on GNSS Data Around the Ukrainian Antarctic Akademik Vernadsky station
Authors S. Doskich, S. Savchuk and I. SavchynSUMMARYToday, the Antarctic continent is almost completely covered by powerful ice systems, which contain 90% of the world’s ice reserves and 70% of the world’s freshwater reserves. Any changes in the ice sheet in Antarctica will have global consequences and require careful monitoring. The GNSS method is an invaluable tool for such research. With the help of GNSS stations located in Antarctica, it is possible to conduct seismic monitoring, determine the amount of ice melting, calculate the amount of water vapour in the atmosphere, and measure ionospheric activity. The main goal of this study is to calculate the zenith tropospheric delays (ZTD) of GNSS stations in Antarctica. The tropospheric delay values were determined based on the data analysis in the double difference (DD) network solution mode and compared with the ZTD data from the PPP precise point positioning method. Calculated tropospheric delays can be used to estimate water vapor content in the Antarctic troposphere, to correct altimetric products for the influence of the moist component of the troposphere, and for remote sensing of the atmosphere.

Geoinformation Modelling of Recreational Resources of National Nature Park “Hutsulshchyna”
Authors I. Zobniv, D. Liashenko and N. KoperSUMMARYThe Natural Reserves Fund (NRF) has a special environmental and other value and functions to preserve the natural diversity of landscapes, maintain the overall ecological balance and provide background monitoring of the environment (Law of Ukraine “About Nature Reserve Fund of Ukraine”). The preservation, development and effective use of NRF, the formation of a national network of environmental protection areas and its integration into the All-European Econet is an extremely urgent task of Ukraine state policy. Nowadays, NRF protected areas, especially national nature parks, regional landscape parks, etc. have become increasingly popular among tourists. The number of recreants and tourists is increasing. Recreants and tourists are important stakeholders in territory management in Carpathian region. They are interested in staying in natural environment and sites with the uppermost visual attractive values. Recreants most of all need high level of natural resources for treatment and rehabilitation (mineral waters, climatic factors, etc.). ( Liashenko et al., 2021 ). That is why the necessity of sustainable recreational nature management is increasing, too. The most powerful recreational nature management instruments are GIS. These technologies are convenient for describing recreational resources quality and availability. They are useful for spatial data analyses, synthesis and visualizing with modern cartographic resources; web maps, web atlases, tourist web portals, etc.

Methods of Building a Digital Relief Model Using the Application of Geoinformation
More LessSUMMARYA digital model of the relief is defined as a digital and mathematical representation of the terrain based on a discrete set of starting points, which allow to reproduce its real surface and structure with a given accuracy. The research uses geoinformation systems Google Earth Pro and ArcGIS 10.2.1 to generate information from the DEM to calculate slope angles and exposure of slopes, the shape of slopes due to the curvature of their transverse and longitudinal sections on the example of model land use. Information about the relief for model land use, located outside the village. Yampil of Murovanska village council of territorial community of Lviv district, Lviv region, with an area of 6.775 hectares for farming was obtained using the Google Earth Pro geoinformation system. The terrain profile of the model land use is plotted, showing that its distance range is 9.95 km, where the minimum elevation is 247 m, the average elevation is 250 m, and the maximum elevation is 253 m. The rise/fall of the terrain corresponds to a value of 50.1/− 50 m, and the maximum slope of the surface is 3.8 and −4.0% with an average value of 0.8 and −0.9%. GPS Visualizer, an online utility that helps create maps and profiles from geographic data, is used to display the DEM of model land use in the ArcGIS geoinformation program. In the geoinformation program ArcGIS, for the construction of the DEM of model land use, a sequence of using the file conversion tool in GPS format, obtained when using GPS Visualizer, based on data of the KMZ type from Google Earth Pro, was performed. The Spline with Barries tool is used, which allows displaying the smallest height value − 246.95 m and the largest − 253.10 m for the model land use.

Study of the Activity of Volcanoes Using Remote Sensing Data and Gis Technologies
Authors T. Korkh, L. Babiy and N. HrytskivSUMMARYThe purpose of the implemented research is to study application of GIS technologies for processing remote sensing data on the example of the Cumbre Vieja volcano eruption. The object of the research is eruption of the Cumbre Vieja volcano, comprising the southern half of the Spanish island of La Palma in the Canary Islands, which began on September 19, 2021 at 15:12 local time and officially ended on December 25, 2021. Since the main task of the work is to study GIS methods to analyse consequences of the volcano eruption the several approaches of GIS analysis were applied. In the first part of the research, we analyzed various band compositions to get proper results and to highlight the lava flows and make their outlines more visible. Next step was to study applications of vegetation indices and as final part there was implementation of image classification for representing the results. We applied this approach to space images obtained for 3 different periods (30.09.21, 10.10.21, 9.12.21) and created a map showing the surface covered with lava and volcanic sediments, which gives the opportunity to visually display the processes of volcanic activity and its progress. The conducted studies showed that the means of geo-informational analysis and the use of remote sensing data provide opportunities for effective monitoring and follow-up of the consequences of volcanic activity. At the same time, it should be noted that for each case of volcanic activity, it is necessary to use separate approaches, due to different natural conditions, which have a significant impact on the content and quality of space images.

Some Aspects of the Creation of Complex Geospatial Features in Modern Geoinformation Systems
Authors N. Lazorenko, Yu. Karpinskyi and D. KinSUMMARYThe process of digitalization of the state, including the development of the national spatial data infrastructure, promotes new requirements for the creation of intelligent core reference data based on international and harmonized national standards and specifications. The main result is digital topographic maps in topographic-geodetic and cartographic production in the cartographic paradigm, that do not take into account the use of new associated features, the rules of the digital description of topographic features, and the rules of topological relationships between map features. Digital topographic maps have a unified content following the Classifier of the information displayed on topographic maps of scales 1:10 000 – 1:1 000 000. This Classifier was developed according to the rule: a feature has its own symbol and topographic code. Geoinformation technologies allow creating of complex features. Therefore, the goal of the research is to formulate the rules for creating complex (associated) geospatial features to ensure the intellectual level of topographic databases, which are the main product of the geoinformation paradigm. The article presents the concept of a complex (associated) feature based on the national standard DSTU ISO 19107:2017 Geographic information. Spatial schema (ISO 19107:2003, IDT). There are four types of collections of terrain objects that are considered in detail: geometric aggregates, geometric complexes, geometric composites, and global geometric complexes. Examples of features displayed on digital topographic maps were given for these types. The established rules for creating associated geospatial features must be taken into account during the development of the specifications of geoinformation products to ensure further compatibility and integration of core reference and thematic geospatial data in the NSDI.

Preliminary Studies of Seismicity Caused by the Water Level Changes in Dnister Upper Reservoir
Authors I. Brusak, K. Tretyak and R. PronyshynSUMMARYThe research presents preliminary studies of seismicity in region of Dnister upper reservoir and confirms the assumption of ( Savchyn & Pronyshchyn, 2020 ) study that claims that the Dnister Hydro Power Complex can be considered as one of the objects where the phenomenon of reservoir induced seismicity has been recorded. Specially installed seismic station «Novodnistrovsk» recorded 956 earthquakes from 2012 to 2021, but only 40 earthquakes are reliably recorded by three or more seismic stations. The earthquakes occur in the contact of structures of different lithological composition at a depth of 1–3 km close to Dnister upper reservoir. Therefore, friction between the structures occur and the corresponding release of energy precisely in the contact zone of the two structures is observed. We calculate the volume changes in the reservoir based on the OpenTopoMap Model in QGIS software and the known changes in the water level from 2012 to 2021 year. The Pearson correlation coefficient between the reservoir absolute volume change and the total seismicity determined through the energy class is 0.64. Further research can be devoted to the search for a functional interrelationship between the parameters, dividing the studied data into equal periods. Similar studies can be carried out at different reservoirs, which have different geological structures.

Pleistocene Climate Fluctuations Recorded in the Magnetic Susceptibility of the Longest Lpss of Ukraine
Authors V. Bakhmutov, D. Hlavatskyi, G. Melnyk, S. Mychak and S. CherkesSUMMARYThe cyclical structure of loess-palaeosol deposits reflects the patterns of climate change and is a valuable archive of palaeoenvironmental information. In various regions of the distribution of the loess-soil sequences (LPSs), palaeoclimatic signals are differently “recorded” in the magnetic properties of rocks, types of fossil soils and the composition of the ancient vegetation. The similarity of variations in the recording of magnetic susceptibility and other palaeoclimate proxies in the same age marine and lake sediments confirms the possibility of palaeoclimatic reconstruction by magnetic properties. In this study, we present rock magnetic and magnetostratigraphic results, in comparison with the lithological-palaeopedological and palynological properties, obtained from the most complete Pleistocene LPSs in Ukraine, at the Roksolany and Vyazivok sections. Our data confirm that the magnetic susceptibility is a powerful tool in the reconstruction of palaeoenvironmental changes, and should be widely used in the study of loess and soil deposits, and in the resolving geological, economic, and environmental problems.

Study of Problematic Issues in Establishing the Borders of Territorial Communities and Entering Data About Them into the State Land Cadastre
Authors R. Kharytonenko, A. Barvinskyi, R. Derkulskyi, I. Kupriianchyk and Ye. ButenkoSUMMARYStudies have shown that the land management project provided for at the legislative level regarding the establishment of territorial boundaries of territorial communities has general requirements, but does not take into account the specifics of the establishment of the boundary when it is entered into the State land cadastre. Stages of work execution in the development of a land management project regarding the establishment of boundaries of the territories of territorial communities are proposed. Emphasis is placed on which existing and conditional boundaries must be taken into account when establishing the boundary of the territory of the territorial community. It is emphasized the need to provide at the legislative level the possibility of determining a part of the boundary of the territory of a territorial community, taking into account the presence of various economic and legal issues and the impossibility of establishing the entire border of the communities that were affected during military operations.

Authors M. Malanchuk, O. Hulko and O. PobutaSUMMARYPolissia in Volyn region is the area of many lakes, which create a strategic potential of fresh water, organic and mineral resources. Thus, the urgent task is to make cadaster accounting of lakes and assess their natural and anthropogenic transformations by using advanced methods of remote sensing (RS) and technologies of geographic information systems (GIS-technologies). The conducted research has confirmed that the water area of the model lake in Polissia of Volyn region is getting smaller due to the effect of natural and anthropogenic transformations. The obtained results of assessment of the temperature regime of the Bilske lake surface by using the data of Landsat-8 (TIRS) in EO Browser show the tendency to raise of the annual average temperature, and therefore, activation of the processes of eutrophication in summer seasons and accumulation of the residues of autochthonous and allochton substances. By analysing space images (Sentinel-1, Sentinel-2, Landsat) of high resolution with different spectral range, researchers are able to assess ecological conditions of the lake by NDVI index, to identify the dynamics of thermal regime of the lake surface. The research confirms the tendency of raise of the water body temperature. The proposed approach to assessment of the ecological conditions of lakes by applying RS technologies is effective both in the methodical and practical terms.

Authors Yu. Onanko, T. Pinchuk-Rugal, A. Onanko, O. Dmytrenko and S. KuzmychSUMMARYIn order to determine the productivity of oil and gas field reserves it is necessary to assess the void-pore space of the reservoir rocks that form them. Atomic-force microscopy and acoustic emission methods were used for this purpose on samples of sandstone SiO2 reservoir rock to study its porosity coefficient. The growth of internal friction maximum height testifies the growth of the structural defects concentration n, and the broadening of internal friction maximum here represents the relaxation process of structural defects new types in sandstone SiO2 reservoir rocks. The structure of the MySQL database of geological information, physical and petrochemical properties of sandstone SiO2 reservoir rocks, special data management procedures have been developed. All results of calculations carried out by the automated system, are recorded in the database in automatic mode, which made it possible to exclude the possibility of entering incorrect data by the operator in manual mode. The measuring of internal friction background after mechanical treatments, temperature gives information about the changes of the elastic strains fields in sandstone SiO2 reservoir rock.

Research and Improvement of Bimetal Benchmark Construction
Authors I. Trevoho, E. Ilkiv, M. Halyarnyk, D. Kukhtar and O. HrushkoSUMMARYIn order to provide a reliable source base for the night networks on large industrial and infrastructure objects, they apply deep-depth monitors. Most often as deep-depth monitors use palm or metal monitors. They are laid in hard rock, which provides reliable storage of high-altitude network level for long time. They are placed as close as possible to the equipment (25–50 m), or directly in the shop ( Baran, 2012 ). The simplest structure of deep rapper - metal or reinforced concrete fuel, clogged at a depth of 20–50 m to the level of root pored. Two pipes are used for the metal rheer: The basic one is made of steel; and auxiliary - made of duralumina and placed in the main pipe. In the base of the river two pipes are fixed to concrete anchor. Inside the main pipe of the river is additionally equipped with a perforated pipe. This allows you to lower the thermometer and measure the temperature of the monitor rod in different depths. At the top of the benchmark you can set the linear movement indicator or mechanical micrometer ( Baran, 2012 ). When the temperature is changed by ∆t=t-t0 (t0, t is the temperature at the first cycle of the neling and the current cycle), the height of the repper tubes is changed by the value entered as an adjustment. The metal repertoire has different constructions. The so-known compensating metal benchmark, which consists of three pipes of different diameter: Two pipes are made of steel, the third one is made of duralumina. The principle of this bi-metal rapper is based on compensation of temperature expansion of two steel pipes with coefficient of linear expansion 12.5•106- and one duralumina pipe with twice the coefficient of linear expansion 22.6•10−6 1/°C ( Baran, 2012 ). This article offers an overview and principle of the author’s bietal pen, work with which does not require additional calculations and calculations of amendments.

Horizontal Deformations and the Stressed State of the Earth Surface Caused by Reorientation of the Shape of the Lithosphere
Authors A. Tserklevych, Y. Shylo, O. Shylo and O. ZayatsSUMMARYThe surface of the lithosphere is geometrically rotated relative to the geoid, and in geological time the orientation of these shapes and the parameters of the ellipsoids that approximate them have changed. This ambiguity between the shape of the lithosphere and the shape of the geoid can create stresses, aimed at masses redistribution within lithosphere in compliance with the shape of the geoid. The parameters of the biaxial and triaxial ellipsoids were derived based on the digital elevation model ETOPO1. The digital elevation model paleoDEM, was used to model the transformation of the shape of the Earth and assess the impact of its reorientation on the stressed-deformed state of the lithosphere in distant geological epochs. Equations for computation of displacements and deformations, which are related to the transformation of the figure and the orientation of the upper shell of the planet, are given. The interpretation of the obtained results of studies of the planetary dynamics of the shape of the Earth’s lithosphere and the global deformation state is given.

Estimation of Accuracy for Solving Incorrect Geodetic Problems
Authors A. Sohor, A. Brydun, Yu. Hubar and O.-M. SerantSUMMARYThe most reliable way for calculating linear equations by the method of least squares, which can be used for solving incorrect geodetic problems, is based on matrix factorization. This method is called singular expansion. Other methods require less machine time and memory. But they are less effective in accounting for input errors, round-off errors, and linear dependence. The methodology of such scientific research is that for any matrix A and any two orthogonal matrices U and V there is a matrix Σ connected by the formula. The idea of the singular decomposition is that properly chosen matrices U and V turn most of the matrix Σ entries into zeros and make this matrix diagonal with non-negative entries. The novelty and relevance of scientific solutions lie in the expediency of applying the singular decomposition of the matrix when obtaining linear equations of the least squares method, which can be used to solve incorrect geodetic problems. The goal of scientific research is to obtain a stable solution of parametric equations of corrections to measurement results in incorrect geodetic problems and its accuracy estimation. The method of solving normal equations by successive elimination of unknown variables (Gaussian elimination) is quite common in geodesy but does not provide stable solutions for ill-conditioned or incorrect geodetic problems. Therefore, in the case of unstable systems of equations, it is proposed to use the method of singular decomposition of the matrix. In computational mathematics this method is called SVD. The SVD singular decomposition method makes it possible to obtain stable solutions for both stable and inherently unstable problems. Such an opportunity to solve precisely incorrect geodetic problems is connected with the use of some limit τ, which can be selected based on the relative errors of the matrix of coefficients of the parametric correction equations and the vector of geodetic measurement results. Moreover, the solution of the system of normal equations obtained by the SVD method will have the smallest magnitude. Thus, applying the singular decomposition of the matrix of coefficients of parametric equations of corrections to the results of geodetic measurements, we obtained new formulas for estimating the accuracy of the least squares method when solving incorrect geodetic problems. The derived formulas have a compact form and make it possible to calculate elements and accuracy estimates quite easily, practically neglecting the complex procedure of finding the inverse of the matrix of coefficients of normal equations.

Theoretical Calculation of the Dilute Aqueous Solutions Activity Coefficients Taking into Account Factors of Electrical Nature
Authors M. Kravchenko, Yu. Bereznytska, L. Vasylenko and S. FedorenkoSUMMARYThe work is devoted to development of the diluted water solutions activity coefficient calculation methodology, using the equalization of the self-agreed systems continuum electrodynamics and allocating processes which are characteristic for the electric system. The dependence of calculated ion activity factors on concentration of diluted water solutions, which are divided into three groups, was obtained. It is justified that for single- and two-valent electrolytes of the first group the influence of the general mechanism of interaction between ions is characteristic, which is determined by the action of ion electric gravity and it`s features. The growth of activity in the area of large concentration values for electrolytes containing hydrogen ion and lithium ion is shown. It has been found that the activity values in the area of electrolytes large concentrations increase is connected with the manifestation of forces of pushing electrical origin in processes, which are accompanied by redistribution of charges. On the basis of equalization for the dielectric component properties of electrolytes water solutions are described. The dependence for calculation of electric field potential, field strength and charge density were obtained. Given the change of diluted water solution internal energy for “i” class ions and free energy is obtained the expression for chemical potential ions. The calculation of the diluted water solutions activity average coefficient is proposed taking into account the nature of electric factors.

Perspectives of Three-Dimensional Modelling of Geodetic Surveys in the Assessment of Real Estate
Authors D. Khainus, T. Anopriienko, D. Sopov, A. Iukhno and M. SavchenkoSUMMARYThe issue of using three-dimensional modeling to create a 3D cadastre in Ukraine is becoming more and more relevant every year. The development of the 3D cadastre will contribute to the introduction of 3D registration, as the registration of not only a certain part of the territory, but also a certain space to which the right of ownership extends according to the law. The creation of a 3D cadastre will contribute to obtaining clearer, objective, reliable, visual land cadastral information about real estate objects, which in turn will have an economic and social effect in the evaluation of land and real estate ( Popov, 2009 ). One of the main tasks of geodetic science is the study of issues of determining the area of the site, its exact geodetic dimensions, geographic coordinates and features of the relief ( Achasov et. al., 2016 ). Also, of great importance is engineering geodesy, which examines areas for future construction, which is quite relevant in today’s realities, for the post-war reconstruction of our country and the assessment of real estate. Modern possibilities for processing and transforming spatial graphic information using computer programs allow solving a wide range of tasks related to the construction of three-dimensional models for construction and land management. The problems solved by applied geodesy are no exception. An important scientific direction of geoinformatics is a set of actions related to the integration of all possible options for collecting, processing and transmitting information with further automatic processing.

The Method of Optimizing Measurements with a Ground Laser Scanner of the Green Plants of T. Masarik Park in Uzhgorod
More LessSUMMARYThe work is devoted to the optimization of the observation space when performing terrestrial laser scanning (TLS) based on the analysis of multiple observation zones and the selection of the minimum number of observation points that maximize the visual coverage of the selected area during the study of green areas. NLS involves the use of maximum resolution and careful selection of scanning locations. When using the sorting method, the number of terrain points increases rapidly, which leads to a rapid increase in the computational requirements for multi-view site planning. In this work, we propose an algorithm for filtering candidates’ points of view with an improved Monte Carlo method for planning TLS when mapping recreational areas of settlements and inventorying green spaces.

Authors I. Trevoho, O. Vanchura, A. Khoptar, P. Periy and V. TarnavskyySUMMARYGeodetic instruments must be examined and metrologically checked for compliance with technical regulations in order to ensure the unity of measurements. In modern geodesy, linear measurements mostly dominate, and metrological monitoring of means of measuring technology (MMT) to transfer them a unit of length from a working standard is carried out on a linear geodetic basis that performs the functions of a working standard. At the same time, the accuracy of the standard objects should be three times higher than the accuracy of the research instruments. A standard linear geodetic base of original design was created and has been operating for many years at the scientific geodetic polygon near Lviv, designed for long-term use, taking into account the accumulated world experience. Considered design features and ensuring measurement accuracy, methods, and results of many years of experimental calibration of the basis and the results of two international metrological reconciliations (carried out for the first time in Ukraine), which confirmed the high stability of the lines of the working standard. National Science Center (NSC) “Institute of Metrology” periodically carried out certification of this basis and it is widely used for scientific research and metrological verification of MMT of various companies and models, by various organizations and enterprises of the country’s geodetic industry.

Research of Agricultural Crops in Kamianets Podilsk Region
Authors O. Stepanenko and P. TrofymenkoSUMMARYAnalyzing the state of agricultural crops and forecasting their harvest is quite important for Ukraine, as these indicators significantly affect its economic situation. Thanks to its fertile soil, Ukraine is called the “breadbasket of Europe”, and it has every chance to become the “breadbasket of the world”. As an exporter of grain (primarily wheat, corn and barley), the country ranks third in the world with 60 million tons of production per year, behind the United States of America and the European Union. More than half of the harvest is sent abroad. Ukraine is also a leader in the world market of oil crops (sunflower, soybean, rapeseed). The country is one of the leading producers and exporters of many other agricultural products ( GO German-Ukrainian Forum, 2020 ). Thanks to conducting a survey of the area of arable land and grain crops, monitoring the condition, growth and development of agricultural vegetation, it is possible to predict various factors: the degree of plowing of the territory, the need to apply nutrients to a certain area of planting, etc. The purpose of this work is to classify grain crops using the methods of remote sensing of the Earth from 2005 to 2022. Research object: Kamianets-Podilskyi district, Khmelnytskyi region. The tasks of the research are: assess the condition of agricultural crops in the Kamianets-Podilsky district of the Khmelnytskyi region; conduct research on the germination of grain plants; analyze the leaf cover of the appropriate area.

Temperature Regime and Ice Cover Dynamics in the Coastal Regions of the Antarctic Peninsula
Authors V. Fedoniuk, Yu. Luhinina, M. Fedoniuk, V. Ivantsiv and S. BondarchukSUMMARYClimate change affects all regions around the world, but the ice covered areas are particularly vulnerable in this case. The Antarctic ice sheet is the largest single mass of ice on Earth. Melting of ice sheets is dangerous, as it can lead to flooding of low-lying coastal areas and other negative processes. In this study, we use remote sensing methods to analyze the changes in air temperature and its impact on the condition of the ice sheets in the coastal regions of the Antarctic Peninsula. Analysis of space images of the Antarctic Peninsula coast for the period 1985–2020 showed that the ice covered area shrinked, as a result, the length of the coastline expanded, and it became more winding. The length of the coastline has increased by 20–25%. Temperature analysis of the investigated area during 1985–2020 (according to the data provided by the Ukrainian Antarctic Akademik Vernadsky station) showed clearly that the average, maximum, and minimum air temperatures have been trending upwards. The average annual air temperature and the average minimum air temperature increased by 1–1.5 0C, the average maximum air temperature during this period increased by 3.30C. This is a sign that global climate change is also impacting the southernmost regions of Earth.
