Data Processing

Data pre-processing includes all steps from the data transfer to the adjustment of the measurements.

Read raw data

• Reading of raw data of various total stations / Levels:
  • Leica GSI-file and DBX 1200 Database
  • Trimble/Zeiss REC500 und M5 Format
  • Trimble/Geodimeter Format
  • Trimble JobXML
• Reading of RINEX files resp. GPS and GNSS measurements and preprocessing using the fully integrated software WA2 (WaSoft, Professor Lambert Wanninger). Use in PANDA: Just GNSS data or in combination with terrestrial measurements.
• Reading of the baseline of various GPS analysis programs, such as Trimble (file extension ode), Leica (SKI) and unformatted text files
• Formatfree reading of SAPOS coordinates, including covariance information.
• Transfer of lasertracker data from Metrolog, Spatial Analyzer (Excel spreadsheet)
• Insertion of gyro azimuths as a separate observation group with own / separate orientation.

Reduction of observations

• Applying instrumental and meteorological corrections to staff reading and distance measurements
• Geometric reduction of the observations on the marked points
• Transformation of 3D baselines in local 2D coordinate differences
• An adaptation to special mesasurement-arrangements is normally possible.
• Further information are given in the manual.

Control of the observations for gross errors and computation of approximate coordinates

• Averaging of to and fro measurements. Warning when limits are exceeded between the measurements
• Logging tools and table heights
• The approximate coordinates are determined in a local system with a robust L1-adjustment
• Transformation of the points from the local system to the system of approximate coordinates by identical points, control of identical points for point mistakes and incorrect coordinates.
