In this paper, a system that enables the use of the most advanced technology based on software, hardware and a combination of measurement technologies was presented. Hybrid Positioning technology enables the use of both methods of measurement - GNNS positioning and optical measurement (total stations) - to save time and improve productivity, as well as work efficiency. MAGNET Field software, in combination with the mentioned hardware solutions, represents a basic component of the hybrid positioning system. The system enables faster measurement in the field compared to robot measuring stations or RTK rovers. It reduces the requirement for conventional traversing methods and constant moving of the instrument. The functionality of the hybrid system was tested during a student field workshop under real operating conditions. A comparison with conventional surveying methods was made, taking into consideration duration and accuracy. [ABSTRACT FROM AUTHOR]

High-resolution global gravity field models play a fundamental role in geodesy and Earth sciences, ranging from practical purposes, like precise orbit determination, to scientific applications, like investigation of the density structure of the Earth's interior. Nowadays, global gravity field models, mainly derived from satellite measurements, become more and more detailed and accurate. An important task of geodesy is to make the gravity field functional available to other geosciences. It is necessary to calculate the corresponding functional as accurately as possible from a given global gravity field models and, if required, with simultaneous consideration of the topography models determined by modern satellite methods independently from the gravity field. This paper is based on seminar papers which were made within the subject "Determination of the Earth s shape" in academic year 2013/2014 (Master Studies, Department of Geomatics at the Faculty of Geodesy, Chair for State Survey). Comparisons of geoid undulations and free air gravity anomalies between geopotential models of 2006, 2008, 2011, 2012, 2013 and 2014 are presented. [ABSTRACT FROM AUTHOR]

Unit for data and spatial service operates within Department for information system and consists of two organization units: Section for data and spatial service and Section for archive and conversion of spatial dana. For the purpose of writing the article we have visited the State Geodetic Administration and within practical assignment elaborated one of the works for legalization. In our example we have elaborated the procedure of recording buildings which had been built before 15. February 1968. For the practical assignment we have used Photoscan ID, Zeiss for scanning diapositives, Epson GT-12000 for scanning copies, internal GIS softver for georeferencing and Adobe Photoshop CS3 for arranging photos.
