Method. Methods of geospatial analysis, in particular zoning of the territory by means of buffer polygons, and also application of a hexagonal grid are used for researches. Results. An algorithm for estimating the state of geodetic support of territories using the method of buffer zones and the method of hexagonal polygons is presented. A comparison of methods is performed and graphical schemes of both methods are presented. The analysis of the results allowed to establish that the state of geodetic support of the territories of the studied areas varies widely. For mapping on a scale of 1:10000 and 1:25000, geodetic support varies between 65–92 %, depending on the area. Bogorodchany district has the highest indicators, Horodenkivsky district has the lowest. The percentage of territories is reduced for larger scales of 1:5000 and 1:2000. Mapping on such a scale requires additional network thickening. The method of hexagonal polygons on average showed better results by 6.4 % than the method of buffer zones. The maximum difference between the calculated collateral obtained from the two methods is 9.7 %; the minimum is 2.4%. Scientific novelty and practical significance. The analysis of the provision of SGN points using geospatial analysis, on the example of Ivano-Frankivsk region, showed the feasibility of its use for these purposes. A comparative analysis of geospatial analysis methods to assess the state of geodetic support based on graphical materials and quantitative characteristics showed that the best results can be obtained using the method of hexagonal polygons. Using the method of buffer zones gives less reliable results. The proposed and researched approach can be used to study the provision of points of the State Geodetic Network for the whole territory of Ukraine, as well as for the territories of individual OTGs, districts and regions.","PeriodicalId":422474,"journal":{"name":"Modern achievements of geodesic science and industry","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125548561","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 aim of the work is to create a thematic map of National Parks and protected areas of Ukraine using GIS technologies. The objectives of the work are to propose a technological scheme of mapping of National parks and protected areas of Ukraine using GIS technologies and to describe the methodology of this mapping. Method. The first step was to search for input data and analyze them. Since the data was obtained from free online services, their geometric correction did not make sense, as they were already bound in the coordinate system WGS_1984. The following 11 layers were then vectorized: nature reserves, biosphere reserves, nature parks, regional landscape parks, reserves, natural monuments, protected tracts, botanical gardens, dendrological parks, zoological parks, parks-monuments of landscape art. An attribute database with the following structure is created for each vector layer: Name – name of the protected area, Oblast – location (region of Ukraine), Area – area of the territory (ha), Type – type of protected area according to the classification. Different symbols of protected objects are designed for each vector layer. In the future, it is planned to compile an atlas of National Parks and Protected Areas of Ukraine based on the created GIS. Results. As a result of this goal, we obtained a thematic map of National Parks and protected areas of Ukraine, which consists of 11 vector layers according to the classification of nature reserves of Ukraine and contains 1204 objects for which the corresponding attribute tables have been created. Practical significance. The practical significance of this work is quite high, because orderly, systematized spatial and attributive information will: help in resolving issues of land management and recreation; improving management efficiency; to promote the provision and development of scientific activity; to improve the information and educational functioning of the objects of the nature reserve fund, etc.","PeriodicalId":422474,"journal":{"name":"Modern achievements of geodesic science and industry","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126133609","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}

Changes in land cover, pollution of air, water and soil, and deterioration of their quality, loss of biological diversity occur for forest ecosystems at the regional and global levels. Climate change, rising temperatures and declining rainfall are provoking the development of pests that are most common in coniferous forests. Remote sensing technologies allow to create forest monitoring systems, including determination of plantation structure, detection of changes in forests due to fires, deforestation, environmental problems, in particular forest drying. The method of detecting changes in forests is based on the use of high-resolution space imagery and on the processing of images obtained from unmanned aerial vehicles to identify healthy, dried and partially damaged by drying conifers in test areas. The result of the study is an image obtained by the method of controlled classification. The accuracy of the classification depends on the choice of signatures, and for that the UAV images are used.

The current state of the tourism industry is characterized by growing demand for tourism services by using GIS technologies and increasing attraction for tourism. Specialists in this field are increasingly using geographic information technology to solve various problems of tourism. This article represents studies and possibilities of comprehensive information technology use in the field of tourism, such as, using of the avalanche pass for a tourist attraction. The information obtained from GIS technologies may have been used not only for travel agencies, but also to be useful for forestry workers but also (because it is an avalanche), should be taken by correspondent rescue services in the winter. Therefore, these studies currently remain relevant for scientific and practical issues. The goal of the work. Show how GIS technology performs the functions of spatial analysis and specific user tasks, such as, data processing, mapping, visualization of tourist routes and areas, etc. Thus, the most common usage of geographic information technologies for the formation of databases and filling mapping atributes about the tourist object and infrastructure of the tourist destination. Improving the informativeness is achieved by visualizing the various characteristics of the object, that is showing the avalanche area, avalanche path and power, which led to the destruction of the forest, and futher on. Method. A tourist route passing through the village of Chernyk, Nadvirna district, Ivano-Frankivsk region, north of Mount Polensky (Polenskaya) was used for this study. The research in this article is based on the use of the extremely destructive snow avalanche that came down from Polensky Mountain in the Ukrainian Carpathians on March 24, 2006 and led to destruction in a large part of the forest in the Gorgany Nature Reserve. Geoinformation modeling methods were used on the territory of the avalanche slope from Polensky Mountain. Results. A digital terrain model of the study area was created. Geotourism route was developed within Gorgan, also some additional studies were performed related to detailed mapping and surface modeling in terms of route safety. Experimental studies were performed based on materials (DEM) provided by the Research Institute, Geodesy and Cartography , also the SURFAR software package was used. On its way, the avalanche destroys not only a large amount of forest (lumber), but also young trees. By cutting and capturing the soil and forest, the avalanche carries all this material (vegetation, top soil, rocks, debris)to the foot of the mountain and changing the terrain as well. According to our estimates, the forest losses caused by this avalanche were as follows: about 2,500 trees were destroyed, or 1,575 cubic meters of lamber. Different models were created for Mount Polenska, which are shown in the relevant figures.

The system does not have a single storage location. The data register is stored simultaneously for all participants in the system and is simultaneously updated with changes, which minimizes the risk of information loss. At the moment, we can trace such a global trend as the use of blockchain technology in various industries, because it affects most industries. We have the opportunity to use blockchain technology from our usual banking operations to real-time finance and real estate. Today, this trend integrates into other industries, which are actively developing and implementing numerous startups. It is safe to say that the blockchain is creating a revolution and today it can be compared with the ingenious invention of the XX century – the Internet.

To date, there are many developments in the definition of elements of EEO. However, there are a number of issues in their practical implementation. This applies primarily to attempts to improve the accuracy of obtaining the coordinates of the points of objects on the ground. Aim. Investigate the possibility of the proposed algorithm for determining the elements of EEO of digital images obtained by aerial surveying from an UAV. Methodology. Based on the condition of collinearity, two types of functions are determined for which the minimum is searched. This process of determining the elements of the EEO is performed using software. A diverse set of programs makes it possible to implement such a search, and a reasonable initial approximation of the EEA and provides a definition of their optimal parameters [Hlotov, 2020; Zavarzin, 2013; Berezina, 2018; Kim Hon Ir, 2017]. Results. The proposed approach was tested on the corresponding digital images obtained by aerial surveying from UAVs at checkpoints, which made it possible to justify the effectiveness of the proposed method. The specified RMSE had the following values: = 0.15 m, = 0.18 m, = 0.40 m. After specifying the steel error = 0.06 m, = 0.03 m, = 0.25 m. The analysis of the unknown results confirms the improvement of the accuracy of coordinate determination by specifying the values of RMS relative to those obtained in the software package Models and the proposed algorithm. Scientific novelty and practical significance. An algorithm has been developed that makes it possible to determine the value of EEO using software without the use of special software for digital image processing. First of all, it makes it possible to improve the accuracy of EEO determination for digital images obtained from UAVs and allows to significantly expand the range of tasks using UAVs.","PeriodicalId":422474,"journal":{"name":"Modern achievements of geodesic science and industry","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114622692","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}

Object of study. The object of the study is the monitoring of the Dniester HPP-1 dam according to the GNSS network data of the stationary system for monitoring the spatial displacement of structures (SSMSDS) of the Dniester HPP-1. The basis of the Dnister SSMSDS are two base GNSS stations additionally equipped with a robotic total station, which are installed on a strong foundation and located at a distance of several hundred meters from the dam. There are control points equipped with a GNSS receiver, antenna and an angle reflector with a 3600 viewing angle on the crest of the dam. The results of GNSS measurements are transmitted to the Leica GNSS Spider software, which processes and determines the coordinates of the base and control points. The GEOMOS software performs a joint estimation of GNSS results and linear-angular measurements. Methodology. To generalize the displacements of GNSS stations of Dnister HPP-1 the method of statistical analysis of time series is used. Authors examine the covariance interrelationships between all GNSS stations of the stationary system for monitoring the spatial displacement of structures (SSMSDS) of the Dnister HPP-1, which are placed on the dam based on the results of measurements from 1.07.2017 to 31.03.2021. For the selected periods of anomalous short-term displacements, the average values of covariance for each GNSS station are calculated. Results. During the period from 1.07.2017 to 31.03.2021 and according to the results of covariance interrelation for most GNSS stations, 3 epochs of anomalous altitude displacements are established (T = 2017.8 ± 0.1, T = 2019.0 ± 0.1, T = 2019.4 ± 0.1). Based on the covariance analysis, it was found that for periods of anomalous vertical displacements, the kinematics of the GNSS station MP01 differs significantly from the kinematics of GNSS stations MP02-MP05. The kinematics of GNSS-stations MP02-MP05 is constant, which indicates the anomalous movement of the unit on which the GNSS-station MP01 is installed in relation to the other blocks of the dam of the Dnister HPP-1. Scientific novelty and practical significance. Authors proposed the method for studying the geodynamics possesses of large industrial areas covered by a network of GNSS stations. Based on the GNSS measurements the periods of anomalous displacement are reveled and further search for spatial kinematic interrelationships between pair of GNSS stations is established. The developed methodology can be used to differentiate the kinematics of structural elements with installed GNSS stations such as engineering structures, industrial areas, geodynamic polygons.","PeriodicalId":422474,"journal":{"name":"Modern achievements of geodesic science and industry","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129850017","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}
