The optimal way to use geoinformation systems with graphical elements of symbols of veterinary significant objects in vector format

A significant problem in the field of standardization in the monitoring of infectious animal diseases is the lack of a system of conventional symbols of veterinary significant objects used in geoinformation technologies, in particular in digital and electronic cartography. The object of the study is the conventional signs of veterinary significant objects, which in the context of display on digital maps can be defined as "non–scalable", marked with corresponding pictograms. A systematic approach has been applied as a methodological basis for the epizootological research method. The basic graphic format of the proposed SVG symbols is used – (Scalable Vector Graphics), which is a modern generally accepted vector format. This article presents the results of cartographic display of pictograms of one of the three sets of symbols for the database – veterinary facilities for various purposes – for which the method of selecting basic signs is used. An algorithm for fixing elements of symbols of veterinary significant objects in the vector format of the SVG geoinformation system with maximum use of free software and secure information technologies is presented. Images in SVG format can be directly represented in current GIS and converted to almost any vector and raster formats without loss of image quality. The algorithm for developing a system of symbols for veterinary significant objects will be used in the Draft of the preliminary national standard in the future.

Development of a GIS-module for analog search using an analytical no-code platform

The article is devoted to the development of GIS-applications for searching analogs of oil and gas objects. Depending on the tasks to be solved and data sources used in oil and gas industry different methods of analogs search are applied. Program products developed on the basis of private methods can be used only to a limited extent, which raises the question about the expediency of resources spent on their development. For efficient creation of programs for analogues search we propose a two-stage scheme including the stage of development of a formalized search model based on analytical no-code platform and the stage of traditional final product development based on the formalized model. It is shown that analytical no-code platforms are an effective and accessible for non-programming specialists means of creating formalized models as a basis for software product development. The expediency of the development of applications for the search of analogs on the basis of geoinformation systems is substantiated. An example of implementing two-stage scheme in the development of module for searching analogs based on free geoinformation system QGIS with the use of Russian analytical no-code-platform Loginom is presented.

A heterogenous-source geoinformation system to manage climate-induced modifications on the landscape for sustainable development

Historical landscapes in Italy have been slowly changing over the centuries and this is because their features, once fixed into specific shapes, were perpetuated until new economic and social developments occurred. Yet, in the Alpine region, this territorial organisation underwent sudden changes after World War II (WW II), resulting in a loss in population and traditional agropastoral production in favour of skiing plants and holiday houses. Moreover, the loss of traditional knowledge pertaining to environmental behaviour has resulted in the urbanisation of lands that are vulnerable to extreme events. In turn, this has hindered sustainable urban development. Nowadays, modern mapping technologies enable the state of the landscape to be assessed before, during, and after extreme events, the increased frequency of which may be related to climate change. The case study examined in this paper is the flood that hit Limone Piemonte, Italy, between the 2nd and 3rd October 2020. On that occasion, an aerial survey of the affected areas was carried out using Uncrewed Aerial Vehicles (UAV) a few weeks after the event. Spatial analyses were also performed based on very high-resolution satellite imagery acquired a few days after the event in order to determine where to plan more detailed three-dimensional (3D) surveys. This has enabled assessments of damages at different map scales to be performed. Thanks to the availability of pre-event multitemporal cartographic reference datasets, it was possible to monitor the historical evolution of the affected areas. It was possible to assess the vulnerable areas before the event, as well as to evaluate the morphological and settlement changes after the disaster. Therefore, one of the goals of this manuscript is to demonstrate that geoinformation systems are among the primary technical tools used to analyse environmental and climatic alterations that impact landscapes. Finally, a 3D model of the affected areas was produced, fulfilling another goal of the research by providing the public administration with a sustainable and innovative tool for territorial and landscape management, in accordance with the 11th pillar of the United Nations Sustainable Development Goals (UN SDGs).

The use of the QGIS tools to determine hydrological characteristics. The experience in higher education

The development of geo-information systems with open access significantly expands the information technology possibilities in the modern educational environment. The use of geoinformation technologies is especially important for STEM specialties, for whom mastering BIM technology is a significant advantage in the labor market. Quantum geographic information system QGIS is widely used by various STEM specialties to expand learning opportunities and gain practical experience of calculations in higher education both in Ukraine and abroad. Morphometric parameters calculation for Ulichka river by QGIS tools is represented in the article. The 1st year master's degree students used QGIS for hydrological calculations. The calculations performed on QGIS were compared with the reference data and cartographic materials of Google map. Calculations showed a high correspondence of the obtained results with reference literature. Modern geographic information systems with free code are not very complex, but require additional knowledge and work skills. Methodical materials and information about additional possibilities of QGIS tools encourage students to study related educational components and search for information on Internet resources, which contributes to the development of the individual student trajectory and stimulates the study of professional English vocabulary. The ability to obtain high-quality illustrative material in the form of scaled maps with reference to coordinates provides the possibility of further use of the obtained material in BIM designs on the Autodesk family software and to use the results in future attestation thesis.

ИННОВАЦИИ В ЖИЗНЕННОМ ЦИКЛЕ СТРОИТЕЛЬСТВА ПОСРЕДСТВОМ ИНТЕГРАЦИИ BIM/ГИС

Innovation in the life cycle of construction is an important topic for the modern construction industry. The introduction of BIM (Building Information Modeling) and GIS (Geoinformation System) technologies into the construction process changes the traditional methodology of designing buildings and structures. The integration of BIM and GIS allows you to improve the accuracy and quality of information in design and construction. This is achieved through digital control and management of data stored in a single database accessible to all project participants. The use of system integration in the design of buildings makes it possible to display much more accurately the achievements of ergonomics and safety, work with energy, optimization of materials, as well as forecasting operating costs. Innovations in the construction life cycle can reduce time and financial costs, as well as improve the quality of work in the entire project delivery chain. This is important for various sectors, including residential construction, commercial real estate and infrastructure facilities. BIM and GIS also help to simplify the interaction between all project participants - from architects and engineers to builders and operational teams. This provides more effective problem solving and improves interaction throughout the project lifecycle. This study is dedicated to the topic of integration of BIM/GIS platforms. This article will describe the main terms and definitions, compare the functionality of the platforms under consideration. The advantages of technology integration will also be presented, the experience of using information modeling technologies used for urban planning activities on the example of a BIM model of a cafe building will be considered. The construction model will be exported from the BIM space to the GIS environment, during which some pros and cons of the transfers are identified, on the basis of which conclusions are formulated about the further application and integration of Graphisoft and Autodesk products.

Current Assessment of the Wetland Carbon Pool in Different Constituent Entities of the Russian Federation

A current more detailed assessment of the bog and wetland areas in the Russian Federation (RF) and the carbon stock in their peat layers has been conducted. Compared to the previous assessment (Vompersky et al., 1994), the creation of the geoinformation system (GIS) “Bogs of Russia” at the Institute of Forestry Science of the Russian Academy of Sciences (Vompersky et al. 2005), allowed to include, in addition to the cartographic basis, replenishable layers of thematic content and to determine the areas of peatlands and carbon stock in their peat layers not only for the whole country, but also for separate constituent entities of the Russian Federation country as a whole, but also for the constituent entities of the Russian Federation. It is important for the administration of each constituent territory to be aware of the peat reserve volumes in order for sustainable nature management to be maintained. It is shown that the area of bogs and marshlands amounted to 328 million hectares, peat stock — to 216.3 billion tons (abs. dry mass). The stock of carbon associated with the peat was 108.7 billion tons. Compared to previous estimates, the area decreased by 11% and carbon stock by 4%. The Annex to the article contains the data on the bogs and wetlands areas, overall carbon stock in their peat layers and specific carbon stocks per unit area of bogs and wetlands for different constituent entities of the Russian Federation. The carbon stocks estimates were also obtained separately for the main groups of bog and wetland habitat types.

Features of the application of geoinformation systems to increase the yield of agricultural land

The main problems in the effective use of land resources as an important factor of the country's development and population's food security are considered. The study was conducted in the northern region of the Republic of Kazakhstan. The object of the study was grain-growing farms in the Akmola region. The study concluded that satellite imagery and unmanned aerial vehicles should be used to monitor crops and assess yields in the Akmola region. These technologies allow for more efficient land management, prompt response to problems and informed decision-making. The experience of GIS application in the United States consists in the formation of database systems for all soil types that are of economic importance. There are 4 national soil databases, as well as several automated soil databases containing data on more than 13,400 soil varieties. The country's Soil Conservation Service has created soil geographic databases, including a geographic database on soil surveys, state soil associations, and major land resource areas. The economic efficiency of land conservation measures will be determined by the amount of net income, taking into account the prevented environmental damage in value form, using the efficiency coefficient of environmental costs relative to the total production and environmental costs. The acreage area in the Akmola region on average for 2018–2023 amounted to 26,264.32 thousand hectares, the average actual crop yield was 12.5 centner/ha. Based on the given system of formulas, the estimated crop yield on non-eroded soils (Yn) is 13.5 centner/ha, and the crop shortfall (V) due to land erosion is 871.88 thousand centners of grain, which is 69,750 thousand tenge at an average grain price of 80,000 tenge/t

Implications of Water Quality Index and Multivariate Statistics for Improved Environmental Regulation in the Irtysh River Basin (Kazakhstan)

The selection of sites for permanent environmental monitoring of natural water bodies should rely on corresponding source apportionment studies. Tools like the water quality index (WQI) assessment may support this objective. This study aims to analyze a decade-long dataset of measurements of 26 chemical components at 26 observation points within the Irtysh River Basin, aiming to identify priority zones for stricter environmental regulations. It was achieved through the WQI tool integrated with geoinformation systems (GISs) and multivariate statistical techniques. The findings highlighted that both upstream sections of tributaries (Oba and Bukhtarma rivers) and the mainstream of the basin are generally in good condition, with slight fluctuations observed during flooding periods. Areas in the basin experiencing significant impacts from mining and domestic wastewater treatment activities were identified. The rivers Glubochanka (GL) and Krasnoyarka (KR) consistently experienced marginal water quality throughout the observation period. Various contaminant sources were found to influence water quality. The impact of domestic wastewater treatment facilities was represented by twofold elevated concentrations of chemical oxygen demand, reaching 22.6 and 27.1 mg/L for the KR and GL rivers, respectively. Natural factors were indicated by consistent slight exceedings of recommended calcium levels at the KR and GL rivers. These exceedances were most pronounced during the cold seasons, with an average value equal to 96 mg/L. Mining operations introduced extremal concentrations of trace elements like copper, reaching 0.046–0.051 mg/L, which is higher than the threshold by 12–13 times; zinc, which peaked at 1.57–2.96 mg/L, exceeding the set limit by almost 50–100 times; and cadmium, peaking at levels surpassing 1000 times the safe limit, reaching 0.8 mg/L. The adverse impact of mining activities was evident in the Tikhaya, Ulba, and Breksa rivers, showing similar trends in trace element concentrations. Seasonal effects were also investigated. Ice cover formation during cold seasons led to oxygen depletion and the exclusion of pollutants into the stream when ice melted, worsening water quality. Conversely, flooding events led to contaminant dilution, partially improving the WQI during flood seasons. Principal component analysis and hierarchical cluster analysis indicated that local natural processes, mining activities, and domestic wastewater discharge were the predominant influences on water quality within the study area. These findings can serve as a basis for enhanced environmental regulation in light of updated ecological legislation in Kazakhstan, advocating for the establishment of a comprehensive monitoring network and the reinforcement of requirements governing contaminating activities.

The Importance of Surveyors and GPS Technology in Systematic Land Registration in Georgia: A Study of the Challenges and Opportunities

The purpose of this work is to explore the historical and contemporary importance of land registration, focusing on the crucial role played by Georgia’s surveyors. The paper concentrates on the combination of GIS-based state systems with GPS PlateTalk map registrations to resolve conflicting cadastral information as well as for accurate ownership record keeping. The Georgian absence of a unified legal and administrative framework significantly complicates land boundary delineation leading to disputes among surveyors. To standardize surveying practices and improve accuracy, an all-encompassing legal framework must be put in place. The study adopts historical, comparative legal, and hermeneutic research methods using examples from Germany and Holland that demonstrate how such advanced technologies as drones, LiDAR, and blockchain can enhance the precision, speed, and security of survey practice. Furthermore, professional education investment must be increased in both teachers and attorneys who are also informed about Geoinformation Systems (GIS), thus enabling them to perform their functions properly when it comes to law matters concerning land registers. Conclusions urge policy-makers to invest in modern technological gadgets as well as engage in legislative reforms that would make their cadastral systems stronger. That would result in the creation of robust cadastral systems by investing in modern technology as well as carrying out legal reforms that would modernize their existing cadastral systems.

Разработка мер по сохранению биологического разнообразия рыб, предложений по организации системы мониторинга состояния популяций редких видов рыб западного региона Республики Казахстан

The purpose of the work is to develop measures to ensure the development of fisheries, the conservation of fish resources and the biological diversity of the ichthyofauna of Western Kazakhstan (Mangystau, Atyrau, Aktobe and West Kazakhstan regions), improving the principles and methods of management and protection of fish stocks. The research was carried out both according to the methods generally accepted in the post-Soviet space, and according to the methods developed by the authors (a temporary method of accounting for the number of fish, withdrawal coefficients for populations of fish with undermined stocks) and methods of foresight research. The monitoring system for rare and endangered fish species should include both in-life research methods and the capture of a minimum necessary number of individuals in order to further domesticate and form breeding herds, artificially reproduce and release the resulting juveniles into those reservoirs. The continued decline in populations of rare and endangered fish species indicates the low effectiveness of the measures taken to preserve them. In order to prevent the loss of the gene pool, it is necessary to select sexual products for cryopreservation during the monitoring process. In addition to monitoring the condition of rare species of fish and other animals conducted by scientific organizations, it is necessary to create a geoinformation system for monitoring rare species, which any resident can replenish by sending experts photos of samples of flora or fauna with observation coordinates. The results of the work are supposed to be used to determine further ways of developing reservoirs in the context of “green growth”.

Identifying managed aquifer recharge and rain water harvesting sites and structures for storing non-conventional water using GIS-based multi-criteria decision analysis approach

In arid climates, conventional water resources are severely limited and stressed in the face of rapid population growth and future climate change. So, it is necessary to find alternative non-conventional water resources for use in drought situations. Additionally, the non-conventional water resources in these areas are not sufficient to meet future water demand. Therefore, non-conventional water resources can be adopted as a strategic reserve to bridge the gap between water supply and demand in case of emergency and drought events. These resources might include rainwater harvesting, treated wastewater, and desalinated seawater. Managed aquifer recharge (MAR) can be applied to store these resources in the hydrogeological system using Geo information System—Multi Criteria Decision Analysis (GIS-MCDA) approach for determining the suitable MAR location for storage. North-west Kingdom of Saudi Arabia area was chosen for this study because it is extremely arid, has high potential for social and economic development, and it has newly constructed non-conventional water infrastructures distributed throughout the area including water desalination plants, Tertiary Sewage Effluent (TSE) waste water plants, and flash-flood storage dams. To identify the suitable MAR site location and structure, different data related to aquifer hydrogeology, surface hydrology, hydrometeorology, and water quality were applied. Then, GIS-MCDA holistic approach was applied with aid of ordered weighting average (OWA) technique. Finally, two maps were created to show the MAR location and structure type. Potential map indicates that ~ 18.85% of the area is suitable for MAR installations. About 0.17% of the total area exhibited very high potential, where infiltration ponds can be applied, 1.86% had high potential for construction of check dams with diversion channels, and 16.82% had moderate potential for installation of recharge wells. Additionally, 56 MAR structures were proposed and a map showing their locations has been created. Thus, results indicated that the study area is promising for MAR installation. These maps could aid the decision makers to propose a sustainable development plan for the future water resources of the area.

Development of farming systems in the Prienisey Siberia

The paper presents the results of research conducted to assess the development of farming systems in the Prienisei Siberia over a long period of time as a basis for identifying factors determining crop productivity, and as an information basis for forecasting crop yields by 2030. The work provides information covering more than two hundred years of land practice in the Prienisei Siberia. It was found that in all the periods of agricultural production, each of which corresponds to a certain farming system, the trend of yield change was positive. Each successive period was shorter than the previous one, with yields increasing significantly. The period of extensive technologies application in farming lasted more than 140 years. At this time, yields increased by 0.0018 t/ha per year. The period of use of the ordinal (low-intensity) farming system lasted approximately 50 years. The yields then increased by 0.0204 t/ha per year. During the period of intensification of the farming system, which took about 30 years, the yields increased by 0.0212 t/ha per year and reached about 2.1 t/ha by the end of the period. The period of formation of high-intensity farming system is the shortest, characterized by the highest productivity growth rates – 0.0639 t/ha per year. If this trend is maintained, the long-term average yield of 3.0–3.5 t/ha will be reached approximately by 2030. For each soil-climatic zone it is advisable to have its own, original farming system, developed taking into account soil-agrochemical properties, landscape and climatic peculiarities, characterized by more in-depth differentiation of individual working area. It should present digital technologies using modern electronic means of informatization, geoinformation systems, remote methods and means of technological processes control, aerial and space methods of agro-ecosystems diagnostics.

On the Methodology of Analysing Aerial and Satellite Images to Detect Archaeological Sites

Today, the use of remote sensing methods is an integral part of archaeological research. The use of various types of aerial and satellite photography at the level of micro-regions makes it possible to collect data on large areas in a short time. The received data are subject to archaeological deciphering – the process of recognition, detection and interpretation of archaeological information based on photographic images of the Earth’s surface. In the course of deciphering pictures, photographic images of objects are analysed, which have a number of decipherable features, that is, characteristic ones by which archaeological objects can be recognised. Modern processing and recording of these data is carried out in geoinformation systems, taking into account their spatial reference. The analysis of domestic publications showed that this direction is promising for future research in Ukrainian archaeology. However, the researchers do not provide a general, clear methodology for working with aerial photography materials and features of archaeological deciphering. Summarising this information prompts the creation of a consistent description of such work. This description is intended to formalise those research operations, which in one way or another were performed by the above-mentioned authors. The paper is an attempt to create a methodology for the archaeological deciphering of aerial and satellite photos for the remote study of archaeological monuments and the protection of archaeological heritage. It is intended to summarise the previous experience of publishing the methodology of working with remote sensing of the land in the archaeology of Ukraine and to structure it on the basis of our own developments. The proposed scheme is not final or mandatory, but only offers one of the options for the approach to thematic deciphering in archaeology. Undoubtedly, the given algorithm of actions will require improvement and expansion as a result of the accumulation of practical experience and theoretical achievements. It is important to emphasise that this branch of archaeology is closely related to technical sciences and technologies in general and therefore requires thoughtful introspection and competent theorising. To obtain reliable results of deciphering in archaeology, it is necessary to always pay attention to the analysis of the research process and the multi-level process of checking its results. The reliability of the obtained data definitely depends on the clarity and awareness of the sholar’s actions, which in turn has a great impact on various fields of archaeological science, and even national security. The reliability of data depends on the “purity” of research operations, which is extremely important in the process of monitoring archaeological objects. The current state of archaeological monuments in Ukraine in the conditions of martial law, and especially on the territories of hostilities, requires urgent monitoring. With the help of modern aerial and satellite photographs, it is especially relevant and necessary today to investigate the damaged archaeological landscapes, wide application of remote sensing of land, satellite navigation systems and geo-information technologies with decoding, for the collection, processing and analysing the information in combination with the data of specific aerial visual surveys using drones and traditional methods of surveys in those areas where it is possible.

FORMATION OF SPATIAL FACTORS ENSURING THE INVESTMENT ATTRACTIVENESS OF REGIONAL LANDS

It has been proven that modern directions and features of land relations at the regional level require a rethinking of approaches to their formation in the context of ensuring the investment attractiveness of regional lands. The purpose of the study is to identify spatial factors in ensuring the investment attractiveness of the lands of the regions. To achieve the goal, the following tasks were solved: to analyze the state and trends of changes in spatial factors; to substantiate the spatial factors of ensuring the investment attractiveness of the lands of the regions. In order to solve the problematic aspects, it is necessary to define and justify the spatial factors of ensuring the investment attractiveness of the lands of the regions, which is an urgent and timely task. A categorical apparatus for determining the investment attractiveness of the lands of the regions was formed, which is based on a set of interrelated spatial, economic, urban planning, ecological, innovative, security, regulatory and legal factors and modern tools of geo-information systems, methods, models, which made it possible to build a quantitative basis for the development of adoption reasoned decisions regarding the attraction of investments in the field of land relations at the regional level. As a result of the study, the factors of land formation and use that affect the investment attractiveness of the lands of the regions and build the foundation for the creation of spatial support are determined. Spatial factors ensuring the investment attractiveness of land at the regional level are determined. The presented factors are an element of a multi-level system of indicators for assessing the level of ensuring the investment attractiveness of the lands of the regions in the context of the development of the integral assessment method. Spatial factors as an important element of investment attractiveness of regional land use are used in mathematical modeling to establish cause-and-effect relationships and create a basis for characterizing further changes. This makes it possible to develop scientifically based recommendations for ensuring the investment attractiveness of regional land use. Keywords: land use, investment attractiveness of land, regions, spatial factor.
