Cadastral measurements of land parcels are conducted under the guidance of territory planning documents designed by resolutions of the Government of the Republic of Lithuania which in turn regulate the collection of real property cadastral data. However, not always boundaries of the measured land parcels correspond to the documents of territory planning and factual consumption of land. This problem becomes obvious when measuring agricultural land which is most frequently formed in land management schemes during the land reform. The aim of the research is to analyze the correspondence of land parcels after cadastral measurements to the documents of territory planning, identifying discrepancies between line lengths and areas of land parcels. Having investigated the correspondence of agricultural parcels to territory planning documents on the basis of the line lengths designed, it was found that higher line lengths occurred after conducting cadastral measurements. Having identified discrepancies between the areas of agricultural parcels and territory planning documents, one can make an assumption that significant differences could be noticed which manifest inadequacy existing in territory planning documents.

The main reason of land fragmentation in Latvia was the restitution of ownership rights to former landowners or their heirs, as well as the land acquisition by other persons in the process of the land reform. As a result the ownership structure was obtained which is not competitive in the aspect of production efficiency. Different instruments as land consolidation, land reallotment and others can be applied for the reduction of land fragmentation. The reduction of land fragmentation should play an essential role in the use of the land corresponding to the spatial development plans which determines perspective land use. Therefore the improvement of the ownership structure should be one of the stages of land use planning.

Remote monitoring of the atmosphere is designed to obtain information about the state of the atmosphere. The principle of the remote monitoring system of the atmosphere is based on the registration and processing of spacecraft radio signals of the Global Navigation Satellite Systems (GNSS). The wet tropospheric delay component of the electromagnetic signal (Δρ sup(tropo) sub(w)), which is derived from the GNSS observations data analysis, is used to calculate the water vapour content in the atmosphere. It is well known, that this parameter is critical to meteorologists, because the water vapour content in the atmosphere is a key parameter in the construction of numerical weather modelling. In this article the IWV - Integrated Water Vapour has been estimated and the expected accuracy of its determination on the basis of the operational GNSS data processing from reference station network ZAKPOS and the results of aerologic sensing of the atmosphere are given.

2014
Celms, A., Latvia Univ. of Agriculture, Jelgava (Latvia) | Ratkevics, A., Latvia Univ. of Agriculture, Jelgava (Latvia) | Rusins, J., Latvia Univ. of Agriculture, Jelgava (Latvia)
Along with the development of the technological possibilities, the Global Positioning Satellite System (GNSS) is increasingly used in geodetic measurements. Using GNSS, measurements are performed in horizontal plane as well as for point elevation determination. The aim of the article is to demonstrate that the GNSS measurements’ static mode has a high accuracy. To achieve the aim the following objectives were set: 1) to perform global positioning measurements in Class I national leveling network, 2) to calculate the elevation above the sea level, 3) to evaluate the accuracy of performed GNSS measurements. The following research methods were used: static measurement method and analytical method for comparison of the obtained data.
Mostrar más [+] Menos [-]Statistical and distant cartography data of abandoned (unused) land
2014
Gudritiene, D., Aleksandras Stulginskis Univ., Akademija, Kauno reg. (Lithuania) | Abalikstiene, E., Kaunas Forestry and Environmental Engineering Univ. of Applied Sciences (Lithuania)
The problem of abandoned agricultural land is relevant in Lithuania, particularly in the territories where poor soils are dominant. The aim of this research is to analyze the statistics of abandoned land in poor soil regions by different estimation methods. The abandoned land was registered for the purposes of the research. Areas might be determined by using statistical data and by applying the results of a distant research method. The initially obtained data showed large differences among the areas of abandoned land determined by different calculation methods, and this might cause a lot of problems, in particular when clarifying the validity of the land taxation. Therefore the initial data of the research concerning abandoned land should be essentially revised. The results of abandoned land accounting and evaluation (inventory) in each territory should be checked and confirmed by the committee of qualified specialists. The reasons of abandonment should be determined for each land plot, and further use of the plot should be determined. Plots of abandoned agricultural land should be estimated for each parcel of the private land and registered in the cadastre data as additional information for estimation of the land tax.
Mostrar más [+] Menos [-]Analysis of farming land usage in Southern Lithuania
2014
Sinkeviciute, V., Aleksandras Stulginskis Univ., Akademija, Kauno reg. (Lithuania)
Peculiarities of farming land usage in southern Lithuania are analyzed in the article. The analysis of archival data and cartographical material reflecting the structure of farming land in Marijampolė, Šakiai, Kazlų Rūda, Alytus, Lazdijai and Vilkaviškis municipalities was accomplished. Information was taken from yearbooks and archives of public institutions of the Republic of Lithuania and other sources as well. It was determined after analysis of collected information that usage and location of cultivated land greatly depend on the land’s productivity. The largest amount of undeclared farming land is in the districts where the land less favourable for farming is dominant. The analysis of the period of last 10 years has shown that the area of farming land decreased by 753 ha in Lazdijai district and by 194 ha in Vilkaviškis district, but increased by 5.5 ha in Alytus district on average per annum.
Mostrar más [+] Menos [-]Verification of set of abandoned lands' data by the field method
2014
Gudritiene, D., Aleksandras Stulginskis Univ., Akademija, Kauno reg. (Lithuania) | Jasiniauskaite, R., Aleksandras Stulginskis Univ., Akademija, Kauno reg. (Lithuania)
The aim of the research was to identify the change of abandoned lands in Ūdrija cadastral area of Alytus district. This particular area was selected due to the diversity of land cover objects and because of a good agrarian condition. According to the data of 2010, the cadastral area of Ūdrija had 176 plots of abandoned land with the total area of 61.41 ha. After the verification 179 plots of a land were found, with the total area of 62.84 ha. It can be said that there is a minor increasing tendency of abandoned lands. During field verification as many as 41 mismatches were identified. The mismatch of the data was influenced by two main factors: a two year period between the information of the data set and field verification, as well as errors of the data set. To sum up, the information of verification has changed slightly. It happened because some mismatches were positive (identified new areas of abandoned land), while others were negative (plots of land which were in a set of data were denied during the verification).
