The speed of measurement carried out using aerial techniques allows us to document the status of railroad construction on a specific day and cover not only individual parts of the project, but its entire scope.

Periodic measurements allow us to perform a comparison of models from different days and calculate changes between them, including balance of works.

Settlement of the balance of earthworks and documentation can be made in the form of:

– tabular settlements between zero state and individual models

– calculations based on cross sections.

On the basis of the acquired data, we can make a number of depictions, for example: overburden and underburden zones, volumes and deviations of overburden zones, inclination of construction slopes.

The method is characterized by high accuracy and elimination of errors resulting from excessive generalization during measurement.
