Claim One:
1. A method for obtaining geospatial data on infrastructure networks by performing mobile laser scanning process, the method comprising steps of: collecting a permission prior to start a scanning and monitoring process; verifying all components of laser scanning system for a proper functioning; performing a real time data validation of the laser scanning system; conducting a mobile laser scanning process by sending the laser pulses; collecting a data from the reflected laser pulses; correcting geometrical errors in a mobile laser scanning point cloud data using GNSS reference station data; generating LAS file by combining surveyed laser data and GNSS data; constructing 3D surfaced based model by using the data from LAS file; analyzing a surface model and extracting a layout of polyethylene infrastructure structures; and observing a diameter, shape extent of the polyethylene pipes using the cross sections of the layout; wherein the speed of the laser mobile unit S is calculated using an equation S = Prm × 726.35 7708.38 Where Prm is the perimeter, and a value of the perimeter is collected from site by a visual inspection.
