The development of GIS technologies, of Earth remote sensing methods, improvement of the legal basis, as well as differences in approaches of creation and functioning of the cadastral systems puts on the agenda the task of using a unified methodological approach for the creation of the cadastral systems. It is particularly relevant during the period of integration and globalization of economic, sociopolitical, scientific and cultural, educational and other programs of different countries and, especially, of the countries of the European Union. The purpose of this research is to attempt to improve the structure of cadastral system with regard to land parcels registration outlining the main directions of scientific and practical research meant for the modernization of the cadastre. The results of the research are suggestions and recommendations about the possibility of creating a unified register of cadastral objects, land parcels in particular, as well as the list of scientific tasks aimed at the modernization and improvement of the cadastral system. The conclusions show that the cadastre should be regarded as the state informational and registration system of geospatial position of the objects, their quantitative and qualitative assessment and legal status at this stage of development of technical, techno-logical and legal trends. In a scientific sense, the cadastre is a branch of science which studies the patterns and principles of formation, functioning and preservation of cadastral objects, information about them and their register.

The solution of preserving and restoring the soil fertility problem of agricultural lands in the process of economic activity is one of the main tasks in achieving global food security. Implementation of a complex of soil protection measures, as a rule, ensures the preservation and even growth of soil fertility. Therefore, the purpose of the article is to determine the economic efficiency of introducing soil protection measures in the use of agricultural land. For this purpose, the following tasks were set and solved: the analysis of the current state and trends of the land resources use in agriculture; to investigate the tendencies of carrying out measures on preservation of soil fertility and prevention of its degradation; to substantiate scientific and methodical estimation principles of economic efficiency of introduction of soil protection measures in the conditions of Ukraine. The following basic methods were used to solve the research objectives: monographic analysis – when developing scientific publications on environmentally friendly use of agricultural land; comparative and statistical analysis – in studying the dynamics of the structure of the land fund of Ukraine by main types of land and economic activity; system-structural analysis and grouping – in the study of the nature and content of ecological and economic consequences of soil degradation, as well as approaches to assessing the economic effectiveness of soil protection measures; economic analysis and calculation of relative indicators – to evaluate the economic efficiency of soil protection measures in the process of agricultural land use; abstract-logical method − for theoretical generalizations and conclusions formation, etc. Established that soil degradation is now one of the most important industrial and environmental issues, which is the main reason for the inability to achieve high rates of environmental and economic efficiency of land use in the future. It was also substantiated scientific and methodical approach to determining the economic efficiency of soil conservation measures in the current market conditions, which is based on the additional income that is received as a result of increase crop yields on protected lands. It is established that effective protection of soils from degradation is possible with the systematic implementation of soil protection measures complex, developed taking into account the specific natural and economic conditions of each region or agricultural enterprise. The priority directions of realization measures on land protection are given.

This article analyses the issue of the inadequacy between the results of preliminary measurements performed during the land reform and results of cadastral measurements. The aim of the research is to analyse the change of areas of land parcels of Sakiai district, the mistakes which were made during the measurements and their causes, as well as to make the comparison between preliminary and cadastral measurements. The research methods are as follows: the review and analysis of scientific literature, the analysis of statistical data, the comparative analysis and the method of graphical modelling. The total area of analysed land parcels is 282718 m2. During the research, while comparing the preliminary data and the data of the measurements of land parcels obtained while performing cadastral measurements, it was established that an average increase of areas of land parcels is 0.0223 ha, decrease is 0.0034 ha, the total perimeter of all land parcels decreased by 24.9 m, the total area of arable land in land parcels increased by 0.1390 ha due to the increase of areas of land parcels, new mapped lands: tree and shrub plantations, grasslands, gardens. The average shift of turning points of land parcel boundaries in the locality after the performed cadastral measurements is 2.64 m. What is more, by applying some formulae, the accuracy of calculation of areas of land parcels was determined. It turned out that land parcels, which cover 96% of the area of the analysed land parcels, changed to the maximum permissible error of areas, and 4% exceeded the maximum permissible error. According to the data presented by the National Land Service it was established that 15% of the submitted cadastral files are not accepted. The most common causes are an inadequacy of land parcel boundaries to the documents of the planning of territories or the land holding projects (44%), mistakes in the preparation of files of cadastral data of land parcel, in the completing (23%), in the preparation of the land parcel plan (21%), and while filling in the form of land parcel cadastral data (13%).

Cadastral measurement provides cadastral data of a parcel determining its boundaries. In theory, based on the legislative regulations, the boundaries of adjacent parcels should not cross the boundaries of parcels, therefore an overlap of parcels is not possible. Yet the question arises if this requirement is met. The study has been conducted to examine the assumption regarding the possible overlap of adjacent parcels when the parcels abut a road. The study object consists of 24 parcels randomly selected from Kėdainiai district municipality, Lithuania which abut the following roads of national significance: road No. 144 (Jonava – Kėdainiai – Šeduva) and road No. 195 (Kėdainiai – Krekenava – Panevėžys) as well as regional road No. 2007 (Akademija – Šlapberžė – Berželė). The cadastral measurements of the selected roads were carried out in the period of 2013–2014. During the study, the analysis of the conditions of overlapping of boundaries and the areas of the overlap have been carried out. The results of the study indicate that the boundary accuracy of parcels is inaccurate in relation to road boundaries.

One of the primary measures of the land reform is to create the national land registry and related land information database, which can be formed only through a complete inventory of land. This article analyses land inventory data in the current stage of land cadastre functioning and development of land relations, as well as discusses justification of organizational and legislative preconditions for land inventory in Ukraine.

The article generalizes theoretical and practical addition to the components of mathematical processing of geodetic measurements, which are the basis and used to support work in land management and cadastre. The research identifies general components of mathematical processing of geodetic measurements and components which are primarily used in the field of land management and cadastre. Completed investigation of the theoretical and practical foundations of these components and developed theoretical and practical additions improve the results of mathematical processing of geodetic measurements.

There are still many drawbacks in legal regulation of construction, cadastral registration of linear facilities, as well as land management in the above-mentioned aspects in the Russian Federation, therefore this study is a theoretical overview and analysis of the existing legal framework. The definition of linear facilities had been incorporated in the City Planning Code of the Russian Federation only in 2016, thus a legal regulation of the issue at stake is of great significance at the moment. The key issues in the area of state cadastral registration and surveying are developing, including cadastral registration and registration of linear facilities and land plots as a united (integrated) complex object of real estate. The results of the research indicate the necessity of developing specific rules for the allocation, construction and reconstruction of linear facilities in addition to determining the legal status of land plots, where such placement takes place.

The land consolidation project of the parts of Vilkaviškis district municipality, Pilviškiai and Klausučiai elderates, Alksnėnai and Sūdava cadastral area is analysed in the article, the main indicators of the project, the meaning of land consolidation, the need to improve the order of the execution and implementation of these activities are described in the article. The survey was carried out to examine the opinion of the participants of the project regarding the advantages of the proceeding and results of the project as well as some of its drawbacks.

Under the conditions of a global reduction in forest areas and climate change, it is important to preserve as many tree-covered areas as possible and understand change trends. The article purpose – aims at identifying forest area change trends of 19th –20th c. in the current forest land of the eldership Raudonė. In the research, historical topographic maps compiled during different periods, and 2019 data from the forest registry are used. The research method of a comparative analysis is employed. The change in forest areas was analysed, and forest areas that remained unchanged for 200 years were identified. The comparison of current forest areas reflected in the cadastral data and forest areas of the considered period allowed identifying the tendency of assigning land the purpose of forest land. During the research, the period with largest forest areas was determined to be the 19th c., and with the smallest – 1st half of the 20th c. During the Soviet period, forests areas were increasing, but did not achieve the same level as in the 19th c.
