The obtained mobile laser scanning constant for the polyethylene infrastructure material is 726 pulses/cm when the system ground speed is 16.49 km/h. The concluded mobile laser pulses constant were used to develop a mathematical method for re-planning the mobile laser scanning missions to obtain the best model for updating the polyethylene infrastructure networks.
