The article presents the analysis of the current situation of the damaged land in Kaunas County. The methods of comparative, analytical as well as statistical and logical analysis were used for the investigation. The aim of the investigation is to carry out the analysis of the damaged land area in Kaunas County during the period between 2005 and 2017. The object of the investigation is Kaunas County damaged land. The study found that the number of affected areas in the county is 409. Because the damaged areas consist of mineral quarries and territories occupied by dumps, the article contains the description and condition of these areas. By 2009, there were 98 landfills in Kaunas County. Kaunas municipal waste management region comprises 6 municipalities; 58 old landfills and dumps were shut down, at present two regional non-hazardous waste landfills have been arranged. In 2017, the damaged land occupied 3,447.36 hectares and amounted to 14.15 percent of all Lithuanian damaged land and accounted for 0.43 percent of the county's area. During the period between 2005 and 2017 the damaged land area in Kaunas County increased by 236.48 hectares or 6.86 percent. The analysis of the damaged land area of the municipalities situated in the Kaunas County showed that the largest of these areas during the period between 2005 and 2017 was in Kaunas district municipality.

Savchuk, S., Polish Air Force Academy, Deblin (Poland) | Doskich, S., Lviv Polytechnic National Univ. (Ukraine)
According to the fast development and distribution of GNSS technologies all over the world, the large numbers of reference GNSS stations have appeared in Ukraine. These stations are included in the state and several private networks. The permanent GNSS observations gathered within these networks are processed and analysed by the Centre of Lviv Polytechnic National University. A cumulative solution (coordinates expressed at the specified epoch and velocities of all stations) was estimated by using the GAMIT-GLOBK software. The authors made several numerous tests using certain configuration of fiducial stations which belong to the EPN A class to transfer ITRF08 frame into Ukraine area and choose the best strategy of alignment of the Ukrainian national GNSS network to the EPN. Three different solutions with cretin tolerance set for Ukrainian GNSS network were estimated and each time the different set of coordinates was obtained. The differences reached several millimetres. Also for verification, our solution was compared with EPN solution. Received coordinates and velocities could have a geophysical interpretation and provide very useful information for local geodesy tasks.

Gecaite, D., Aleksandras Stulginskis Univ., Akademija, Kauno reg. (Lithuania) | Jankava, A., Latvia Univ. of Agriculture, Jelgava (Latvia)
Land consolidation – an important stage of agricultural and rural development. This is a significant land use planning process, when private, municipal and state land parcels located in rural areas are redistributed in a complex way, their boundaries and location are changed by the prepared land consolidation project of a certain area. Recently, there has been a lot of talk about the benefits of land consolidation to farm structure and productivity, restructuring of rural areas and development, but there is not enough emphasis on the benefits of our environment, landscape and biodiversity. Experience of European countries shows that the land consolidation projects can be useful not only for farmers, but also for our environment and its individual components. The article gives an overview of not only the positive aspects of environmental preservation. The fact that the land consolidation projects can bring negative results (i.e. that they are implemented without regard to the sustainable transformation of the territory) is noted as well.

2017
Perovych, L., Lviv Polytechnic National Univ. (Ukraine) | Begin, S., Ivano-Frankivsk National Technical Univ. of Oil and Gas (Ukraine)
This article is concerned with the problem of establishing process equipment deformation regularities, in particular, gas engine compressors at the compressor station of underground gas storage facility in Bohorodchany due to ground topographic surface vertical movements caused by gas flooding into and extraction from the reservoir bed in different seasons. Values of longitudinal and lateral pitches of gas-engine-compressor units’ foundation plates were determined using the results of topographic surface vertical movements monitoring. This provides an opportunity to predict adverse processes in gas engine compressors operation. On the other hand, this monitoring facilitates resolution of land resources sustainable and efficient use issues at underground gas storage territories.

2017
Heldak, M., Wroclaw Univ. of Environmental and Life Sciences (Poland)
The subject of the paper is the change trends in the trade in undeveloped land and real properties designated for agricultural and forestry purposes in Poland with respect to the value and surface area of real properties sold. Another aim of the study is to present the differences between average transaction prices of undeveloped real properties designated, among others, for residential, industrial, agricultural and forestry purposes. The research covers the period starting from the accession of Poland into the European Union structures. The Polish real property market has been very active in the analysed period. The analysis of tendencies in real property sales transaction values in Poland in the time period from 2004 to 2015 demonstrates that the increasing trend prevailed from 2004 to 2008. Then, in 2009, the value of transactions decreased in comparison to the preceding year.

Tsvyakh, O., National Univ. of Life and Environmental Sciences of Ukraine, Kiev (Ukraine) | Openko, I., National Univ. of Life and Environmental Sciences of Ukraine, Kiev (Ukraine)
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).

2017
Savchuk, S., Lviv Polytechnic National Univ. (Ukraine) | Kalynych, I., Uzhhorod National Univ. (Ukraine)
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.
