The scope of this paper encompasses the comparison of photogrammetric measurement techniques with satellite RTK measurements. The aim of the research is to compare and combine the measurements taken by using three different techniques as well as to determine which of them is the most precise compared to the results of satellite RTK surveying. To convey the research, four measuring sets were used: a GPS receiver, a mobile laser scanner, UAV (unmanned aerial vehicles) as well as so-called ?photo bus? (a mobile mapping system). The measurements took place in the autumn 2016 during maintenance works on a state road near the city of Konin, Poland. Based on comparative analyses it can be concluded that the most precise method, comparing to RTK measurement, was laser scanning. The results of such surveying represent the error limit of ±5 cm, which is the most accurate outcome in comparison with the other methods. Moreover, no external factors had influenced the results of laser scanning as it occurred in the case of drone and photo-bus measurements.
