Topographical maps are usually made for already existing roads, for their reparation, reconstruction and inventory. The measurements can be made using different measuring methods and large range of geodetic instruments, from the optical instruments to laser scanning systems. The quality of topographical maps is very important, because roads (streets) are strategic object of a country. The aim of this study was to evaluate the differences between the current measurement methods of producing topographic maps, namely, laser scanning and tachometry. The measuring methods for road and street mapping were analysed and compared, including their technological properties, potentials and efficiency. The results show that the main differences between these methods in composing topographical maps is the measurement and data informativeness, the speed of processing, the level of detail of the results and applicability possibilities.

Keywords: topographical survey; mobile laserscanning; total station; line engineering construction; road and street mapping.
