Contribution on study possibilities in using instruments of different technical performances in establishing special purposes leveling networks in engineering geodesy

Examination of possibilities in using geodetic (survey) instruments of the same specifications, but different technical performances is always an interesting geodetic topic. The main purpose of this research is to analyze the accuracy of special purposes leveling networks where height differences were measured with Koni 007 CZJ and Leica DNA 03 levels. Obtained results showed that both leveling results fulfill the required conditions of precision leveling, but the preference is given to level DNA 03.
