Conclusions
Using Mobile Liders have a number of decisive technical and economical advantages for making civil engineering works for roads, real roads, runways and other similar objects: accuracy within 1-2 cm, direct geopositioning, productivity up to 30 km per day.
Main technological stages (calibration, data acquiring, office processing) are automated which guarantees achieving reliable output materials.
Output includes precise 3D models including DTM, DSM, deformation, edges, crevices, cavities, traffic lane marking and so on.
Drakkar ltd. is fully equipped and has an extensive experience for any kinds of mobile laser scanning works in Israel and globally.
