Abstract
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.
