Stakeout and Control

Coordinate CalculationAxis3D COS greatly simplifies the professional analysis of measurement data. Accurate trigonometric results are guaranteed by reliable adjustment routines that take refraction into account. Easy evaluation of leveling data minimizes analysis effort and the intuitive user interface guides users through the program.
Data ManagementUsers can manage large volumes of data individually and by project. Coordinates of reference points, profile-related points, and other project points are stored securely, as are shutter definitions and cross-sections for profile checks. The clear data structure provides a quick overview of the entire project.
Stakeout and ControlVarious calculation routines are available for stakeout and control tasks, such as plumbing points onto center lines, 3D lines, and 3D planes; point calculation along center lines and 3D lines; construction laser calculations; coordinate comparison. NATM-profile and TBM guidance checks can be evaluated easily and displayed in clear graphics.
