Network adjustment

The CARD/1 Network Adjustment provides quick and clearly structured evaluations of your network measurements

• Combined plan and height network adjustment
  Various network types
  
  • Fixed point networks with plan and height connections to existing or datum points
  • Free networks
• Definition of the starting data
  
  • Central management of the starting data in the CARD/1 databases for points, measurement values and instrument data
  • Easy-to-use measurement data selection from the set-ups pool
  • Automatic existing point assignment (optionally via on-screen selection)
  • Instrument-dependent accuracies (optionally as presettings)
• Approximate coordinate determination
  
  • Automatic calculation
  • Optionally from point database
• Calculation of the adjusted coordinates, network accuracy and reliability
• Automatic elimination of questionable observations (optional)
• Easy checking and editing of the network sketch in the base map graphics
• Optional determination of instrument-unknowns: scale factors and additive constants for distances
• Optional determination of object point coordinates
• Comprehensive reporting
• Results preview

• Technically sound network display
  • Independent-of-scale visualization in the base map
  • Technically sound symbols for points, distances and directions
  • Annotation with point numbers and observations
  • Observations; if required as normalised correction and redundancy component
  • Error ellipses (configurable scale)
  • Height error indicators
  • Pointings for object points
• Coloured markings for the error status
  • Markings for questionable observations
  • Marking of the ellipse if the positional error has been exceeded
  • Marking of the height error indicator if the height error has been exceeded
• On-screen editing of the network sketch
  • Deactivation/activation of questionable observations simply by  mouse click
  • Sorted list of the questionable observations
  • User-definable window sections and zooming
