This article is devoted to the study of geodynamic processes in the Tysza River basin within the Transcarpathian region with an analysis of geodetic observations obtained over the past decade. Method. Karst monitoring began with the identification of the most dangerous areas of the earth's surface that are subject to vertical displacements. After the detection of the most dangerous areas the local geodetic monitoring was carried out at facilities within the urban settlement to prevent possible accidents: Solotvyno, Dilove and Bila Tserkva. A collection of archival aerial photography was also used to develop a methodology for identifying changes in landscapes and landforms under the influence of geodynamic processes. Results. UAVs were used to remove karsts. On the basis of digital aerial photography data were created: orthophotos and digital terrain models. Digital aerial photography was carried out in accordance with the requirements of regulatory documents. To determine the dynamics of landslides and karst the digital aerial photography must be repeated several times at certain intervals. Aerial photography work was carried out in two stages in 2020 and 2021 Contour points were selected for identification marks. They are recognized on aerial photography and the terrain with an accuracy of at least 0.1 mm on the scale of the created plan. Mathematical processing of geodetic GPS measurements was performed using Trimble Geomatics Office software. After photogrammetric processing, the quality control of the obtained results was performed and digital surface models using DEM and TIN methods. Orthophotomaps on a scale of 1:1000 were made from raster images of aerial photographs, taking into account the created digital terrain model. There is a need for monitoring work to update information on the state of modern karst formations and areas with exogenous processes in Solotvyno and Bila Tserkva, Tyachiv district and the village Dilove, Rakhiv district, Transcarpathian region. The technology of topographic and geodetic works with the use of UAVs and GPS measurements in mountainous areas has been developed and tested. The results of aerial photography were used to visualize the study objects and to convey information regarding the deformation processes to local governments. For processes of natural or man-made nature (displacement, landslides, karst) requires the development of individual approaches to the use of UAVs. With the mass use of UAV images, a data bank is formed, which cannot be obtained by other methods. The study made it possible to create the method of complex determination of movements in exogenous and technogenic areas in mountainous areas with the use of the latest technologies. It allows quick establishing a plan-altitude basis of the required accuracy in the reference coordinate system in solving a number of applied geodesy problems using satellite technologies and UAVs for observations by objects.

Methodology. The TEC and the data of global ionospheric maps (GIM) for the SULP station were used in the work, as well as the data from the Ionolab website for better clarity, where the nodal values of the TEC are essentially used, from the same global ionospheric maps (GIM). The essence of the research was to compare the values of TEC, obtained by the two above-mentioned methods in different periods of solar activity (a high solar activity-data for 2013, a low solar activity-for 2018). Results. It was determined that the differences of TEC at a low solar activity are mostly negative and reach ≈8 ТЕСU, and at the peak of solar activity both were measured and the model TEC values were basically the same and varied in range from 0.3 to 6.8 ТЕСU. Scientific novelty. The variations of the values of total electron content TEC for the SULP station in different periods of the manifestation of solar activity were obtained and given and it was established that at a low solar activity the measured TEC values prevail over the model values by more than 20 % and do not exceed ≈6 ТЕСU, and at a high solar activity both the model and the measured values are practically the same and range approximately from 4 to 31 TECU. Practical significance. The results obtained can be used for constructing regional maps and the velocities and direction of ionospheric stain movements, as well as in solving some issues for a certain region.

There are numerous potential causes of landslides, including both natural and man-made ones. Their growing frequency raises alarm due to the often catastrophic consequences of these events. The monitoring of regions prone to landslides is a multifaceted undertaking that involves the use of several technologies and approaches, such as geospatial technology and modeling. The primary objective of this work is to construct a spatial analysis model for a region in northwestern Romania that is susceptible to landslides. A case study was conducted to estimate the susceptibility of landslides in a monitored region located near Sighetu Marmației, Romania. To achieve this objective, a combination of several technologies and approaches were used, such as remote sensing, land surveying, aerial photogrammetry, geographic information systems, and spatial modeling. The research region underwent landslide susceptibility evaluation by processing geo-information data using Geographic Information Systems (GIS) and developing a prediction model based on the MaxEnt (Maximum Entropy) approach. The research's distinctive contribution is integrating geo-information data acquired from the hazardous site utilizing geomatics methods into a novel geo-monitoring system. The research offers valuable insights into the monitoring of landslides, adding to the current body of literature by introducing an expanded paradigm. The study's theoretical and practical implications might be valuable for professionals, local authorities, emergency response agencies, and other parties involved in mitigating the danger of landslides.

The methodological basis of the study is a combination of methods of field research and geoinformation analysis using GIS, which allowed to identify the main centers of the highlands of Chornohora of rockfalls, screes, landslides and linear erosion. On the basis of the landscape approach the spatial differentiation of geological and geomorphological processes in high altitude terrains and landscape structures is analyzed and their complex analysis is carried out, and with the help of geoinformation and statistical data processing on location and number of cells the intensity of negative processes is calculated. The main result of the study is a map of the distribution of negative geological and geomorphological processes (rockfalls, screes, landslides and linear erosion) in the landscape complexes of the subalpine and alpine highlands of Chornohora, as well as a map of a key area near Smotrych Mountain, which expresses landscape processes at the level of landscape striyas and tracts. As a result of the research the structure and specifics of development of geological-geomorphological processes in geocomplexes of different origin and with different morphological and morphometric parameters are analyzed. The influence of geological structure on the development of processes is manifested in the dominance of massive sandstones and sandstone flysch, which contributed to the development of large and steep landforms with inherent intense rockfalls, screes and linear erosion. The analysis of the intensity of the manifestation of these processes testifies to their greatest development in the geocomplexes of ancient-glacialexarational genesis-corries, cirques, glacial troughs, nival niches, etc. The development, nature and intensity of the manifestation of negative geological and geomorphological processes in landscape complexes of nival erosion and denudation genesis differ significantly. The peculiarity of the differentiation of processes here is their clear dependence on the composition and peculiarities of the occurrence of bedrock stratum, relief morphometry and so on. An important result of the study is the above-mentioned map of the highlands in the vicinity of Smotrych Mountain, which expresses the previously little-studied landslides to the narrow bands of argillites and argillite flysch. Originality. The relationship between the diversity and distribution of negative geological and geomorphological processes with the genesis of landscape complexes of the Chornohora highlands, their structure, structural-lithological and morphometric features is determined. Landscape differentiation and intensity of rockfalls, screes, landslides and linear erosion in the highlands of the studied massif are analyzed and described. Practical significance. The results of the study contribute to the further study of the dynamics and properties of highlands landscape complexes of Chornohora, as well as provide an opportunity to predict the peculiarities of the geological situation and optimize the nature management system, in particular-organizational features of recreational and tourist activities.

Methodology. The main criterion for evaluation of the authenticity of the old plans is the study of their geometric accuracy, which is determined by the magnitudes of errors that arise when measuring lengths, angles, coordinates, and other cartometric attributes. For the investigation of accuracy, quantitative method used direct measurements of the lengths of lines and angles between two directions in the oldert and modern plans and analysis of these measurements based on the statistical theory of errors using the Gauss and Bessel formulas. Results. According to this methodology, for each plan, the mean square error of the distance, the angle of rotation, and the mean square error of the directional angles were determined. These characteristics made it possible to compare the errors of linear and angular variables of two time-varying and multi-scale plans of Lviv to each other and concluded that the plan of Lviv in 1931 is more accurate with respect to the angular measurements. Distortion distances are characteristic for both Lviv's plans. Nevertheless, there was less relative mean square error is in the plan of 1931, despite its smaller scale. The calculated distortion coefficients of the lengths of lines and the amplitude of fluctuations of the boundary values of the scale denominator made it possible to carry out the analysis of distortion in different parts of the plan and to continue the study of the accuracy of the above-mentioned cartographic materials using graphical research methods that allowed us to evaluate and illustrate spatial variations of errors, as well as to detect and understand the facts and technical aspects of creating these cartographic works. Scientific novelty and practical significance. The determination of the geometric accuracy of the 1844 plans of Lviv, as a tool for scientific research, is relevant since it enables us to evaluate the cartographic publication as a result of human activity more objectively and fully. Numerical data obtained during such a research made it possible to compare the cartographic, documentary, and content values of old plans. The quantitative technique chosen in the study of Lviv's old plans, based on direct measurements of the lengths of lines and angles between two directions, made it possible to compare the errors of linear and angular variables of timevarying and multi-scale plans of Lviv. Having been calculated in this research, this methodology can be used to evaluate the accuracy of other plans of Lviv and any other city.

This paper analyzes the problems that occur with the current classification of state geodetic networks in the modern world. Постановка проблеми. Класифікація геодезичних вимірів, що була розроблена понад сімдесят років тому для забезпечення побудови планових державних геодезичних мереж традиційними наземними геодезичними методами (тріангуляції, полігонометрії, трилатерації), у своїй основі базувалась на прийнятих тоді методах побудови планових мереж та методиках вимірювань. Це було зумовлено поточним станом справ у геодезичній галузінаявним парком геодезичних інструментів, досвідом проведення попередніх робіт, залученням до покриття новоохоплених територій іншими аспектами польових і камеральних робіт тощо. Серйозним випробуванням для традиційної класифікації геодезичних вимірів стали супутникові вимірювання, які не вкладаються у наявну класифікацію. Зв'язок із важливими науковими і практичними завданнями. Висвітлені в цій публікації питання тісно пов'язані з Основними положеннями створення Державної геодезичної мережі (ДГМ) України. Основні положення побудови ДГМ встановлюють загальні вимоги та принципи її побудови, моніторингу її пунктів і передбачають побудову ДГМ із застосуванням як сучасних глобальних навігаційних супутникових систем (GNSS), а також допускають використання традиційних геодезичних методів.

Results of experimental check of accuracy one of frequency GPS-receivers on control points of a real geodetic network in region Zakarpatja are resulted. Постановка проблеми у загальному вигляді. За останні півтора десятка років став доступним для використання значний потенціал Глобальної системи визначення місцеположення (GPS), призначеної для навігації та визначення координат різних об'єктів, для наукових та прикладних досліджень. Головними факторами бурхливого розвитку GPS є її всепогодність, оперативність, висока точність, малі габарити приймальної апаратури, простота експлуатації і відносно невелика вартість. До цього слід додати, що конфігурація орбіт GPS-супутників дозволяє практично з будь-якої точки земної поверхні приймати сигнали щонайменше від чотирьох супутників, а як показує практика спостережень їх число коливається від п'яти до десяти. Висока точність забезпечується принципом вимірювань, який базується на визначенні псевдовідстаней "GPS-супутник-GPS-приймач" за різницями фаз сигналів, прийнятих від супутників, та сигналу, що генерується приймачем. Вищенаведене визначає актуальність і перспективність використання GPS для рішення широкого спектру наукових задач, пов'язаних з вивченням Землі:

The methodological basis of the study is a combination of methods of field research and geoinformation analysis using GIS, which allowed to identify the main centers of the highlands of Chornohora of rockfalls, screes, landslides and linear erosion. On the basis of the landscape approach the spatial differentiation of geological and geomorphological processes in high altitude terrains and landscape structures is analyzed and their complex analysis is carried out, and with the help of geoinformation and statistical data processing on location and number of cells the intensity of negative processes is calculated. The main result of the study is a map of the distribution of negative geological and geomorphological processes (rockfalls, screes, landslides and linear erosion) in the landscape complexes of the subalpine and alpine highlands of Chornohora, as well as a map of a key area near Smotrych Mountain, which expresses landscape processes at the level of landscape striyas and tracts. As a result of the research the structure and specifics of development of geological-geomorphological processes in geocomplexes of different origin and with different morphological and morphometric parameters are analyzed. The influence of geological structure on the development of processes is manifested in the dominance of massive sandstones and sandstone flysch, which contributed to the development of large and steep landforms with inherent intense rockfalls, screes and linear erosion. The analysis of the intensity of the manifestation of these processes testifies to their greatest development in the geocomplexes of ancient-glacialexarational genesis-corries, cirques, glacial troughs, nival niches, etc. The development, nature and intensity of the manifestation of negative geological and geomorphological processes in landscape complexes of nival erosion and denudation genesis differ significantly. The peculiarity of the differentiation of processes here is their clear dependence on the composition and peculiarities of the occurrence of bedrock stratum, relief morphometry and so on. An important result of the study is the above-mentioned map of the highlands in the vicinity of Smotrych Mountain, which expresses the previously little-studied landslides to the narrow bands of argillites and argillite flysch. Originality. The relationship between the diversity and distribution of negative geological and geomorphological processes with the genesis of landscape complexes of the Chornohora highlands, their structure, structural-lithological and morphometric features is determined. Landscape differentiation and intensity of rockfalls, screes, landslides and linear erosion in the highlands of the studied massif are analyzed and described. Practical significance. The results of the study contribute to the further study of the dynamics and properties of highlands landscape complexes of Chornohora, as well as provide an opportunity to predict the peculiarities of the geological situation and optimize the nature management system, in particular-organizational features of recreational and tourist activities.

Methodology. The main criterion for evaluation of the authenticity of the old plans is the study of their geometric accuracy, which is determined by the magnitudes of errors that arise when measuring lengths, angles, coordinates, and other cartometric attributes. For the investigation of accuracy, quantitative method used direct measurements of the lengths of lines and angles between two directions in the oldert and modern plans and analysis of these measurements based on the statistical theory of errors using the Gauss and Bessel formulas. Results. According to this methodology, for each plan, the mean square error of the distance, the angle of rotation, and the mean square error of the directional angles were determined. These characteristics made it possible to compare the errors of linear and angular variables of two time-varying and multi-scale plans of Lviv to each other and concluded that the plan of Lviv in 1931 is more accurate with respect to the angular measurements. Distortion distances are characteristic for both Lviv's plans. Nevertheless, there was less relative mean square error is in the plan of 1931, despite its smaller scale. The calculated distortion coefficients of the lengths of lines and the amplitude of fluctuations of the boundary values of the scale denominator made it possible to carry out the analysis of distortion in different parts of the plan and to continue the study of the accuracy of the above-mentioned cartographic materials using graphical research methods that allowed us to evaluate and illustrate spatial variations of errors, as well as to detect and understand the facts and technical aspects of creating these cartographic works. Scientific novelty and practical significance. The determination of the geometric accuracy of the 1844 plans of Lviv, as a tool for scientific research, is relevant since it enables us to evaluate the cartographic publication as a result of human activity more objectively and fully. Numerical data obtained during such a research made it possible to compare the cartographic, documentary, and content values of old plans. The quantitative technique chosen in the study of Lviv's old plans, based on direct measurements of the lengths of lines and angles between two directions, made it possible to compare the errors of linear and angular variables of timevarying and multi-scale plans of Lviv. Having been calculated in this research, this methodology can be used to evaluate the accuracy of other plans of Lviv and any other city.

This paper analyzes the problems that occur with the current classification of state geodetic networks in the modern world. Постановка проблеми. Класифікація геодезичних вимірів, що була розроблена понад сімдесят років тому для забезпечення побудови планових державних геодезичних мереж традиційними наземними геодезичними методами (тріангуляції, полігонометрії, трилатерації), у своїй основі базувалась на прийнятих тоді методах побудови планових мереж та методиках вимірювань. Це було зумовлено поточним станом справ у геодезичній галузінаявним парком геодезичних інструментів, досвідом проведення попередніх робіт, залученням до покриття новоохоплених територій іншими аспектами польових і камеральних робіт тощо. Серйозним випробуванням для традиційної класифікації геодезичних вимірів стали супутникові вимірювання, які не вкладаються у наявну класифікацію. Зв'язок із важливими науковими і практичними завданнями. Висвітлені в цій публікації питання тісно пов'язані з Основними положеннями створення Державної геодезичної мережі (ДГМ) України. Основні положення побудови ДГМ встановлюють загальні вимоги та принципи її побудови, моніторингу її пунктів і передбачають побудову ДГМ із застосуванням як сучасних глобальних навігаційних супутникових систем (GNSS), а також допускають використання традиційних геодезичних методів.

Results of experimental check of accuracy one of frequency GPS-receivers on control points of a real geodetic network in region Zakarpatja are resulted. Постановка проблеми у загальному вигляді. За останні півтора десятка років став доступним для використання значний потенціал Глобальної системи визначення місцеположення (GPS), призначеної для навігації та визначення координат різних об'єктів, для наукових та прикладних досліджень. Головними факторами бурхливого розвитку GPS є її всепогодність, оперативність, висока точність, малі габарити приймальної апаратури, простота експлуатації і відносно невелика вартість. До цього слід додати, що конфігурація орбіт GPS-супутників дозволяє практично з будь-якої точки земної поверхні приймати сигнали щонайменше від чотирьох супутників, а як показує практика спостережень їх число коливається від п'яти до десяти. Висока точність забезпечується принципом вимірювань, який базується на визначенні псевдовідстаней "GPS-супутник-GPS-приймач" за різницями фаз сигналів, прийнятих від супутників, та сигналу, що генерується приймачем. Вищенаведене визначає актуальність і перспективність використання GPS для рішення широкого спектру наукових задач, пов'язаних з вивченням Землі:
