The total station position is calculated using standard Leica functions. Observations are then made to reference points for post-processing of position, height and orientation of the instrument. Assigning point IDs and positioning to targets can be automated.

The design geometry is exported from Axis3D COS office software and loaded onto the total station. On site, points are set out relative to the design geometry with Axis3D ETU using stationing, height, or offset values from centerline, profile arc length, or radial distance from nominal profile. Furthermore, it is possible to stake out the intersection point of any given 3D line with the design geometry.

For as-built checks coordinates of single points can be viewed directly on site, either in reference to the center line or to the nominal profile. The automatic linescan of as-built profiles – with the added option of omitting certain areas such as ventilation ducts – enables quick, comprehensive control. Each scan point is positioned automatically by an iteration, to find the correct chainage and arc-lengh.

General

• Axis3D ETU operates with the entire design geometry, including profile enlargements, loaded onto the total station (exported from Axis3D COS). Pre-calculating stakeout points is unnecessary.
  
• Making use of Leica Viva Imaging functionality (coming soon)
  
• Save all program settings
  
• Measurement data and coordinates stored in ASCII files in Leica GSI8 or GSI16 format
  
• Point coding consistent with other Axis3D products
  
• Optional: logging of all activities on the total station
  
• Program continues after power fail
