Inventories of the traction network is performed with airborne laser scanning. The speed of this method allows us to increase the scope of the survey several times over the classical geodetic measurements and avoid generalization, while maintaining comparable accuracy.
Measurements performed using aerial techniques do not require traffic restrictions on railroad routes and minimize risks affecting the safety of those performing the inventory.
Using specialized software, we subject point clouds to classification and the final result is a study in vector form.
The advantage of the study is automation and speed.
