... because the Earth's not flat

New Features and Enhancements

• Least Squares Network Adjustment and Import Points options - Modified Leica SKI import of GNSS point and baseline vector observations to permit variable point-ID field sizes and variations in the range of record types expected

New Features and Enhancements

• New Pan function added for instant left mouse button operation; simply down-click, hold, and draw the vector. Note: The old View menu Pan option is still available but there is a slight difference in the manner in which the two functions operate
• Survey → e-Data Sokkia SDR processing - Adds processing of simple traverse from raw Face1 and/or Face2 observations
• Least Squares Network Adjustment - 2D-Horizontal adjustment can be made of network consisting of only point observations, no other observation types required; any job type
• Least Squares Network Adjustment localisations - 3D-Similarity transformation parameters computed during localisation can now be saved to the Definitions Library for re-use in other jobs
• Points menu Import, Export and Transform Job options: 3D-Similarity Transformation can now be used in PLANE jobs using parameters saved to the Definitions library from a localisation in Least Squares Network Adjustment or entered directly into the library

Bug Corrections

• Manual Traverse - Direction observations may now contain non-zero orientation readings
• eData processing of 'Geoida Standard Extract File' - Form settings not saved - FIXED
• eData processing of Sokkia SDR - Case "13" data line was truncated in log-file - FIXED
• Least Squares Network Adjustment, 'Coord. Observations' tab - Numerous display issues, corruption of cell values, prompting to save without the data having been changed; also, after saving Grid coordinates with 'Coord Obs. Type' set as 'Job Datum' and later returning to the form, the points would be displayed as invalid Geographic values, and on attempting to correct the display to Grid, the points would then be displayed with all values as zero - FIXED
• Points menu Import, Export and Transform Job options: Block-Shift (Plane) transformation - "Error 11 in g_spher (Class Module) cLatLong::Function FootPointLatRad# - Division by zero" when point source or target coordinates are PLANE - FIXED

New Features and Enhancements

• Least Squares Network Adjustment
• Coordinate Observations ('Coord. Observations' tab) can now be included with all job types including PLANE (2D mode) for Localisation or Least Squares adjustment, however valid point heights must be used although they may be zero. Now can do localisation and adjustment with only Coordinate observations (defined in the 'Coord. Observations' tab) as the only observation data type, no other observation types are required; set 'Coordinate Type' to 'Non-Geodetic' for 2D mode ('Job Datum' in 'Plane' jobs)
• 2D Localisation for the purpose of deriving transformation parameters, can now be done in a geodetic job where there is no point height information. All points can be set to a single value (eg 0.000), and in 3D-Terrestrial mode with 'Coordinate Type' set to 'Non-Geodetic', horizontal 2D transformation parameters are derived: a single rotation in the Z-axis, and scale and translations in the horizontal plane. Least squares adjustment follows the localisation if required
• Adjustment Summary now includes list of raw coordinate observations prior to localisation

Bug Corrections

  • 'Coord. Observations' tab - the Height 'Std-Dev' field is changed to blank even after a valid value has been entered - FIXED
  • 2D-mode localisation not including 'Coord. Observations' tab observations, with message "No observation data in the current LS data set" - FIXED
  • Localisation - "Error 6 in g_impexp (Class Module) cLocalisation::Sub VectorCoeffs - Overflow" when attempting Localisation in 3D-Terrestrial mode - FIXED

Bug Corrections

• Alpha-numeric point IDs (Points → AlphaNumeric ID X-Ref) - Database error when saving Description longer than field size - FIXED

Bug Corrections

• Closing Geoida with 'X' button on title bar - When a loaded job has been changed but not yet saved before closing, the prompt "Changes have been made ... Save now ?" appears to ask the user the action required, ie Yes, No or Cancel. If the Cancel button was clicked, Geoida would still close and lose any changes made
• Pressing the F1 key to display Help for a loaded form - some forms would fail to display the Help file
