    • Analyses oh height education of geographic information systems in Lithuania 

      Sužiedelytė Visockienė, Jūratė; Kumetaitienė, Aušra; Špūraitė, Jurgita (17th International symposium on "Modern technologies, education and professional practice in geodesy and related fields": with a special session for young specialists and students exhibition: papers : 08-09 November 2007, Sofia, Bulgaria, Europe, 2007)
      The subject of paper is to present information about Geographic Information System (GIS) in the Lithuania and discussed related problems. In the four universities teach GIS or subject with GIS contents. They are the Vilnius ...

    • Calculation of corrections due to unparallelism of axes of instrument 

      Renata, Bagdžiūnaitė; Zakarevičius, Algimantas; Sužiedelytė Visockienė, Jūratė (16th International Symposium on “Modern Technologies, Education and Professional Practice in Geodesy and Related Fields", 09-10 November 2006, Sofia, Bulgaria / Union of Surveyors and Land Managers in Bulgaria, 2006)
      The errors that appear due to unparallelism of axes of distance measuring instruments are discussed in the article. The presented formulae are used for eliminating those errors. The main axes of the instruments can be ...

    • Estimation of spatial deformations of the Earth-crust in the Ignalina nuclear power plant region by applying the data of GPS monitoring 

      Zakarevičius, Algimantas; Aksamitauskas, Vladislovas Česlovas; Stanionis, Arminas (16th International Symposium on “Modern Technologies, Education and Professional Practice in Geodesy and Related Fields", 09-10 November 2006, Sofia, Bulgaria / Union of Surveyors and Land Managers in Bulgaria, 2006)
      Spatial Earth-crust deformations have been assessed by finite element method, the algorithm for determining deformations has been compiled. Experimental analysis has been carried out on the site of Ignalina Nuclear Power ...

    • Geotectonic interpretation of recent earth crust movements in sedimentary basins 

      Zakarevičius, Algimantas; Puzienė, Rūta; Anikėnienė, Asta (International symposium on "Modern technologies, education and professional practice in geodesy and related fields" : papers : 3-4 November 2005, Sofia, Bulgaria, 2005)
      Benchmarks used for geodetic observations are established on the Earth's top layers. The measured amplitudes are a sum of tectonic crust movements and non-tectonic deformations of sedimentary layers. The model assuming ...

    • Improvement of railway topographic plans updating technologies 

      Sužiedelytė Visockienė, Jūratė (16th International Symposium on “Modern Technologies, Education and Professional Practice in Geodesy and Related Fields", 09-10 November 2006, Sofia, Bulgaria / Union of Surveyors and Land Managers in Bulgaria, 2006)
      There are presented the peculiar technologies on the update of topographic map linear objects to scale 1:500–1:2000. Due to that resulted peculiarities make aerial photographs, carrying out digital aerial triangulation, ...

    • Research of spatial tectonic stresses based on results of geodetic observations 

      Zakarevičius, Algimantas; Aksamitauskas, Vladislovas Česlovas; Stanionis, Arminas (17th International symposium on "Modern technologies, education and professional practice in geodesy and related fields": with a special session for young specialists and students exhibition: papers : 08-09 November 2007, Sofia, Bulgaria, Europe, 2007)
      For investigation of spatial movements of the Earth-crust the cosmic geodetic methods were applied. A polygon consisting of 10 geodetic benchmarks was established in 1998. The positioning of the sites was adjusted taking ...

    • Strain and stress modelling of the earth's crust of the GPS polygon of the Ignalina nuclear power plant 

      Zakarevičius, Algimantas; Šliaupa, Saulius; Stanionis, Arminas (International symposium on "Modern technologies, education and professional practice in geodesy and related fields" : papers : 3-4 November 2005, Sofia, Bulgaria, 2005)
      The study is aimed at the unravelling the current tectonic activity of the Ignalina Nuclear Power Plant area. The GPS geodynamic polygon was established in 1998 to measure vertical and horizontal movements of the Earth's ...

    • Technological peculiarities in production large scale orthophotogrammetric mapping for urban areas 

      Sužiedelytė Visockienė, Jūratė; Renata, Bagdžiūnaitė; Kumetaitienė, Aušra (International symposium on "Modern technologies, education and professional practice in geodesy and related fields" : papers : 3-4 November 2005, Sofia, Bulgaria, 2005)
      The article deals with the possibilities of large-scale (1:1000 - 1:2000) orthophotograph mapping for urban areas, compilation of color orthophotograph maps applying latest technologies. Technological specifications and ...
