Date of Mobile Data Collection: 05/01/2016
Date of Vertical Clearance Extraction: 5/26/2017
Extraction Methodology: Point clouds from the mobile scanner (Leica Pegasus 2) and static scanner (Leica P40) were used due
to the areas being difficult to access with conventional methods. The Leica Cyclone clearance measurement tool was utilized to find
the lowest vertical clearance (VC) location. Once the lowest VC was found a planar patch was fitted to the roadway surface and the
measurement was taken from the lowest VC point normal to the created patch per the “Draft ODOT Vertical Clearance
Measurement” document (dated 01/13/2017).
Accuracy Statement: The Leica Pegasus 2 Mobile Mapping System has a stated vertical accuracy of 0.015m RMS.
Assumed Intended Use: Per Region 1 survey request, the project team needs to validate the existing condition to assess vertical
clearance impacts and coordinate with Department of Motor Carrier.
Highway Number, Milepost, and Structure Number: Multiple – see following photos.
All vertical clearance measurements were performed by Jonathan Rawlings and Sam Farber-Kaiser in March 2017 using point clouds
provided by the Geometronics unit, static scans completed by Region 1 Survey, and Leica Cyclone software (v9.1.5).
