The Trimble GEDO Rec-Scan system consists of the Trimble GEDO CE 2.0 track measurement trolley with a Trimble control unit in combination with a laser scanner and a Trimble total station. 

The system adds a laser scanner to a Trimble GEDO Rec geodetic system with a Trimble total station or Trimble GNSS receiver. An absolutely referenced three-dimensional point cloud is generated, which can be used for as-built data collection for the design and construction phases, and for clearance analysis in tunnels or at any narrow points. 

The system can be used in combination with the Trimble GEDO GX50 as well as with classic terrestrial laser scanners, such as Trimble TX6 and TX8, or Faro Focus S70A.


  • Control of geodetic track survey
  • Synchronization with GEDO Scan measurements
  • Capturing of absolute track position with track gauge, superelevation (cant) and twist



  • Control of the kinematic capture of laser scan data in conjunction with track gauge, cant (superelevation ), twist and chainage information
  • Live view of the current profile and clearance check in real-time (depending on laser scanner model used)

GEDO Office

  • Analysis and further processing of GEDO Rec measurements
  • Station setups and measurement data can be re-calculated in case control point coordinates have changed
  • Track sections taken from different station setups are merged into one resulting track
  • Variance comparison between measured track and design alignment
  • Quality reports for track position
  • Comparison of measurements from different epochs for track monitoring purposes


GEDO Scan Office 

  • Pre-processing and visualization of three-dimensional point cloud data captured in the field
  • Generation of an absolute referenced three-dimensional point cloud
  • Track specific analysis of point cloud data
  • Measurement of object distances relative to the track centerline
  • Clearance analysis with static or dynamic clearance profiles as well as wagon models
  • Neighboring track detection for tracks visible in the scan
  • Overhead line detection and distance measurement
  • Registration of points and lines directly from the point cloud
  • Generation and vectorization of cross sections with DXF output
  • Additional modules (i.e. WinLUE, Clearroute, Banedanmark) for clearance analysis according to track infrastructure operator requirements.
  • Use of a universal track measurement trolley with modular expansion options
  • Modular design allows the use of a terrestrial laser scanner also for other surveying tasks
  • Flexible alignment of the laser scanner for better object visibility
  • Simple and fast detection of bottlenecks without impact on train traffic
  • High resolution and detailed capture of objects
  • Specialized software for evaluation and documentation
  • Navigation in the point cloud along the track axis

  • Support of different calculation methods for clearance analysis with static or dynamic clearance profiles (wagon model, country-specific calculation methods, etc.)
  • Neighboring track detection for tracks visible in the scan
  • Overhead line detection and distance measurement

Planning, BIM and construction

  • Documentation of the current state
  • Basic data capture for planning and 3D modeling purposes
  • Planning basis for the track alignment 
  • Clearance analysis with static or dynamic clearance profiles or wagon models for current or newly planned track alignments or for the use of new train sets
  • Overhead line planning
  • As-built documentation after completion for operation and maintenance phases
  • Final inspection and variance comparison after completion of construction phase



  • Clearance analysis for extra-wide transports and cross-border rail traffic
  • Construction documentation for track infrastructure operators (i.e. WinLUE for LIRA, Clearroute)


Asset management
