The article reveals difficulties to make managerial decisions as to optimization of recreational objects’ location considering economic and technological parameters of an impact with application of fuzzy modelling. The authors propose methods of evaluation of alternative variants of managerial decision making applying programs of Mathcad with the further prospect of choosing alternatives.

The article presents the Lithuanian forest land change in the period of more than a hundred years. The causes leading to forest land use change are analysed in the article. The beginning of forestry in Lithuania can be traced back to Sigismund Augustus times starting from 1557, when Wallach reform was launched. However, over time forest land and its use evolved for a variety of political, social and economic factors. In 1795 the state-owned forests in Lithuania amounted to 35% of the total area of forests; other forests were owned by landlords, churches and kulak farms. Later forests were cut down quite rapidly, many of them burned down, but reforestation work was insignificant. The smallest forest coverage during the analysed period was in 1945, just 16.5%. Forests were thinned out, wastelands and waterlogged areas dominated. Later, albeit with different variations, the forest coverage of Lithuania increased and today forest area accounts for more than 34% of the total area of the country, the majority of which are private forests. More detailed characteristics of forest land use and user trends as well as their causes are presented in the article. It also looks at the possible prospects.

Land as a production factor occupies a special position in the economic activities of the urban population. Land resources in big cities are not only territorial basis for placing industrial and production structures, but also a space for urban life in general. However, to assess the effectiveness of urban land use, primarily the ecological and economic potential of the use of the urban land resources should be determined aimed at sustainable development of urban agglomerations (Volodchenkov, 2010). The rapid pace of development of large cities in the world and an increase of their impact on the environment and society is accompanied by the set of economic, ecological and social problems which significantly influence the development of settlements in general (Stolʹberh, 2000; Onyshchuk, 2001). However, the process of urbanization as a result of rapid scientific and technological revolution requires large areas for deployment of large scale production facilities and urban settlements in the conditions of natural resource management (Kontorovich, Rivkin, 1986).

The national geodetic infrastructure of Ukraine has developed rapidly into Ukrainian Coordinate Reference System UCS – 2000, a fully GNSS compatible coordinate reference system, which is realised through networks of active GNSS stations. They provide data for post processing and streamed raw data for real-time network (RTN) solutions. The RTN raw data are currently being used by both Trimble (ZAKPOS Network), Leica Geosystems (System Solutions Network) and Topcon (TNT - TPI Network) to provide independent RTN solutions. This study is the first in the public domain to evaluate the performance of RTN services in Ukraine and it is intended to provide guideline information for geo-spatial practitioners. Based on collecting RTN data at five locations and using standard observing and processing methods, an accuracy of 25 mm ±10 mm with respect to 2D coordinates and 34 mm ±14 mm with respect to the heights was achieved. The three systems were shown to be generally comparable although some initialization problems were experienced. The result has revealed expected ~2-5 cm (95%) precision for the horizontal and vertical components; however, large horizontal and vertical biases were observed, which can be as high as 8 cm.

Land management and improvement of computer technologies in land use are one of the most important tasks of the state; their effective implementation is closely linked to the widespread implementation of modern achievements of information technology. The achievement of the maximum transparency of the processes is vital in the field of geo-information and spatial data resources during increasing the reliability and manageability of the infrastructure.

The article shows results of compiling recommendation land use maps for land use and land resources management of the university experimental farm “Velykosnitynske”. Large-scale GIS mapping of experimental farms allows to improve land use and decision making, prepare recommendations to solve land management issues, planning of technology processes and efficient crop growing technology. Compiled recommendation maps are aimed to assist in rational land use planning and sustainable development of the territory.

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 changes in the ownership structure were to be implemented by the Agricultural Property Agency of the State Treasury, which, under the Act of Law of 11 April 2003 on the structuring of agrarian system (i.e. The Journal of Laws of 2012, item 803, as amended), on 16 July 2003 became the Agricultural Property Agency with eleven local branch offices. For the purposes of this article the monographic method was used for the overview of relevant literature and legal provisions, whereas the statistical analysis was employed in the data of the Central Statistical Office and reports on the activities of the Agricultural Property Agency. Until the end of 2015 the main objective of the Agricultural Property Agency was to restructure and dispose of the assets within the Agricultural Property Stock of the State Treasury. Since its foundation, the Agency expanded the Stock by 4.74 million ha. Over time, the operating conditions for the Agency were in a state of flux – they were being adjusted to the changing socio-economic situation. At the beginning, leasing was the basic form of disposal of the Stock land. After Polish accession to the European Union an increased interest in the acquisition of agricultural property was observed. By the end of 2014, as a result of land sale, free-of-charge land transfers or other transactions, approximately 3.2 million ha were disposed of, i.e. about 70% of the whole land which was taken over. Currently, according to the legal provisions, long-term lease is the basic form of disposal of the Stock land.

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.

Land cover objects are reflected in a set of georeferential data and are constantly changing. These changes can be accurately examined by computer and interactive information systems. One of the main advantages of computer information systems is the fact that their maps can be constantly improved and updated. The update of georeferential data was conducted in a selected area using the ArcGIS software. After the analysis of the Lithuanian land cover data, the area meeting the following criteria was selected: a diverse landscape, the abundance of different objects (built-up areas, forests, bodies of water), an adjacent city and good access to major metropolitan areas. The article presents the updated georeferential data and tracks changes in the updated data of built-up areas, areas overgrown with trees and shrubs, dams, swimming pools, lakes, ponds and roads in the selected area within the period from 2008 to 2015. The results revealed that changes occurred in all analysed layers. It proves that land cover objects are constantly changing. The greatest change was observed in the data of built-up areas. In comparison with 2008, in 2015 even 41% of built-up areas was changed (i.e. the old boundaries were revised, new and defunct built-up areas were discovered), 125 new areas have overgrown with trees and bushes and 46 changes were observed in ponds and pools.
