Testing of the digital levelling instrument DiNi 22 and possibilities of its applications.
SEVERA, Tomáš
The aim of this diploma work was to test, to judge the accuracy and possibilities of applications of the digital level Trimble DiNi 22. It is a precise digital compensatory nivelating appliance, whitch together with a code invare rod answers the requirements for nivelation measuring with 0,7mm/km exactness of both - way nivelation. The exactness of measuring is always influenced by the conditions when the measuring is carried out. Atmospheric conditions infuence the measurement of all geodetic instruments and that is why the major part of this diploma work is dedicated to verifying the influence of atmospheric conditions on the accuracy of the digital level DiNi 22 measuring. For this purpose from September 06 to February 07 were repeatedly measured in different weather conditions separate points of different heights of the nivelation level line Mg 02 České Budějovice - Hluboká n. Vltavou line, which is a part of the nivelation net of IV. line.
