Abstract
A method of surveying a section of a railway to determine amounts of soil to be excavated or added at selected position coordinates of track locations includes moving a survey vehicle along the railway, optically scanning the track structure at selected intervals to obtain optical data points with position coordinates, recording images at the intervals with position coordinates, recording position coordinates of drainage points, processing the optical data points to derive ditch overlays formed by ditch profiles associated with locations along the track and ditch templates, detecting anomalous soil unit weights associated with track locations, reviewing images associated with the locations of the anomalous units, adjusting the ditch overlays as necessary, and loading the adjusted data into a computer of an excavator device for display to guide an excavator operator in reshaping the ditches along the track according to the detected position of the excavator device.
