Evaluation of tacheometric measurements

Central management
Central management
  • Central data management; import measurement data of any common tacheometer into a central measurement database
  • Measurement data already checked during the import
    Missing connecting points
    Ambiguous points
    Contradictory point codings
    Contradictory point comments

Easy evaluation

Clearly structured measurement sketches which can be edited on-screen are available when evaluating your measurement data. Questionable observations are marked. The position and quality of your measurements are therefore immediately visible.

  • Combined calculation of position and height
  • Automatic calculation of mean values of sets of observations
  • Batch evaluations
  • Extensive plausibility checks
  • Checks according to the set value limits
  • On-screen editing and clearly structured measurement sketche
    Marking of questionable observations
    Marking when value limits have been exceeded
  • Calculation of stations (observation points) and intermediate points in one go
  • Instrument-dependent corrections for the observations are taken into account
  • Any reductions are taken into account
  • Calculation of the accuracy values
  • Mean calculation menu for points measured more than once
  • Comprehensive reporting
  • Results preview
  • User-defined print layouts

Measurement sketches editable on-screen

Traverse calculation
Traverse calculation
  • Technically sound and clearly structured measurement sketches displaying the observations, deviations and error values
  • Displays the error status of the current calculation (errors, questionable, error-free)
  • On-screen editing of measurement sketches to activate/deactivate observations and pointings

Saving coordinates and heights

  • Checking differences to existing points
  • User-definable modes: automatic mean value calculation or overwrite mode
  • Mean calculation dialogue displaying the deviations

User-definable formulae management

Formulae management
Formulae management
  • User-definable formulae to calculate the permissible deviations for distances which have been measured more than once; e.g. for lateral, longitudinal and height misclosures of traverses
  • Formulae management
  • Formulae are taken into account when evaluating the measurements

Instrument management

  • Central management of all instrument data required for the calculations, e.g. instrument errors and accuracies
  • Instrument errors and accuracies can be taken into account when performing evaluations

Coordinate transformation

  • Transformation parameter calculations
    On-screen editing of control point sketches displaying residuals
    Anzeige des Fehlerstatus (fehlerverdächtig, fehlerfrei)
    Error status display (questionable, error-free)
  • Transformation parameters can be saved for follow-up transformations
  • Transformation methods
    3-parameter-transformation
    2-point-transformation
    Helmert-transformation
    5-parameter-transformation
    5-parameter-transformation (Baden-Württemberg)
    Affine transformation
  • Optional residual error distribution using various methods
    Distance-dependent: 1/S, 1/S², 1/(S*√S)
    By triangular network

Setting-out values from planning data

  • Setting-out data for points
  • Setting-out data for alignments, alignment parallels and widths
  • Offset calculations in reference to a survey line
  • Setting-out reports

Evaluation of chain surveys

  • Error checks
  • Scaling factors for abscissa and ordinate values are taken into account

Surveying-related constructions

  • On-screen definitions
  • Intersection sketches
  • Various intersection calculations
    • Straight intersections

  • Area management including theoretical and actual areas

Base map data evaluations

  • Distance and polygon calculations
  • Triangle and circle calculations
