The Trimble GEDO Scan System is a modern, efficient tool to collect detailed information about track and surrounding features. With Trimble GEDO Scan you can quickly gather precise, high-resolution data for use in track clearance assessments and facilities management.
The Trimble GEDO Scan system utilizes a Trimble TX5, TX6, TX8 or Faro Focus 3D laser scanner to collect high-resolution datasets of 3-dimensional points. The scanner is mounted on a GEDO trolley, which collects location, gauge and cant information as it is moved along the track. The combined data produce detailed 3D models of tunnels, overpasses, stations and other facilities where precise information is needed for railcar clearance and asset management.
The Trimble GEDO Scan Office 2.0 software combines data from the GEDO Scan and GEDO Rec field operations to produce a 3D point cloud.
Trimble GEDO Scan can operate in two modes. The Local mode for track clearance analysis captures information based on the offset from the rail to nearby objects.
In Absolute mode, the system can create 3D point clouds and tie objects to the rail as well as defined coordinate systems.
For railway specific 3D visualization and analysis, Trimble GEDO Scan Office 2.0 uses clearance envelopes and 3D models to simulate the movement of a railcar through an existing facility or stretch of track. The system can automatically detect locations where clearance encroachments may occur. For detailed analysis, Trimble GEDO Scan Office 2.0 can create cross section drawings and compare differences according to given profiles or envelopes.
As well these 3D data can be shared with Trimble RealWorks and other design systems.
