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%).

Geoportal.lt is a Lithuanian state information system whose scope is to allow all data users to freely access geographic data, maps and e-services. The portal also allows drawing relief altitude profile and set the altitude of point on location. It is performed by applying the tool “Set altitude of point on location”. It is one of the newest tools of geoportal.lt website, whose accuracy has not been analysed, and which, according to the information provided by GIS Centre, complies with the requirements set for 1:50000 scale maps. This tool is selected as an object of research, while the aim of the research is to analyse the accuracy of data provided by Lithuanian spatial information portal tool “Set altitude of point on location” in case of different land covers. The following methods of investigation have been employed: literary analysis; the analysis of cartographic material; field measurements and data processing; comparative analysis of data. The data is processed using Geomap and Microsoft Excel programmes. After the analysis has been carried out, it was established that the most common errors in all types of land covers are from 0.5 m to 1.5 m. Such errors comprise 70 per cent in forest areas, 35 per cent in built-up territory, and 53 per cent in thin land cover. Taking into consideration that the website geoportal.lt operates on the basis of orthographic map whose accuracy is 1 meter and the discussed tool shows the altitude of the nearest known point, it can be stated that the obtained presumptions are permissible. To summarise the obtained data, the tool is reliable. The reliability of the data is 91 per cent in thin land cover, 86 per cent in forest area, 75 per cent in built-up area. To compare it with topographic maps of analogous format, where the errors of altitudes may reach up to 10 meters, the tool is reliable even in case of major errors.

Ivaviciute, G., Aleksandras Stulginskis Univ., Akademija, Kauno reg. (Lithuania)
The article presents the comparative analysis of the Kaunas city anthropogenic landscape change during the period between 2006 and 2014. For this analysis the land fund statistics of the Republic of Lithuania were used. The components of anthropogenic landscape change are graphically shown in the figures. During the analysis the Kaunas city statistics were compared with the data of Kaunas County and the Republic of Lithuania. Comparative, analytical as well as statistical and logical analysis methods were used for the investigation. The object of the investigation is anthropogenic components of Kaunas city. The aim of the investigation is to carry out the analysis of the change of Kaunas city anthropogenic components in the period of 2006-2014. The work analyses the change of urban landscape components, the reasons of the established change. The built up territories comprise the majority of anthropogenic landscape of Kaunas city i.e. 90.05 per cent, while the damaged territories make up 0.06 per cent and Kaunas city roads constitute 9.89 per cent of the analysed landscape. It was established that during the analysed period the built-up territories of Kaunas city increased by 312.78 ha i.e. 3.53 per cent. Within 9 years the road area increased by 14.04 ha or 1.44 per cent, while the damaged areas increased by 1.89 ha. Having analysed the statistical data of Kaunas city anthropogenic landscape areas it was estimated that within the period of 2006 -2014 the area of these territories increased by 328.71 ha or 3.34 per cent. e area of these territories increased by 328.71 ha or 3.34 per cent.

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.
