       The initial georeferenced scanning of the profiles is considered
       as the reference section line for comparison with the scans that
       eventually will follow.


       From this data the absolute movement of the tunnel can be
       evaluated, as well as the relative convergences in each section.

       Clearance


       Besides knowledge of track geometry, complete knowledge of                              Clearance Sections
       the utilizable clearance in the rail network is absolutely essential
       for reasons of safety and economy.
       Working with kinematic or stop & go mode, mobile scanning
       data can be collected for rail tracks environment, regardless in
       tunnel or not.

       Using the predefined clearance envelope, the system can give to
       the operator on-the-fly information about the obstacles violating
       the train’s free profile. The scanning data can be also stored for
       further analysis and documentation.


       Numerical data concerning the allocated obstacles can be                         Clearance projection map
       presented in 2-D profiles and “iso-violation” curves in 2-D map
       projection of the tunnel surface. This gives at a glance the
       location and the size of the problem.


       Applying this methodology we benefit:


       •    Speed – minimum time presence in track
       •    Safety – minimum personnel presence in track
       •    Full profile measuring
       •    Real Time allocation of obstacles
       •    Fully automated recordings
                                                                                      Tempi rails clearance control
       •    Easy to use documents
       •    Real Time gauging results
