New release: Version 5.8 (24 August 2017)


The primary feature of interest in this release is the addition of entries in the Definitions library relating to the new Australian GDA2020 geodetic datum. To add the new items to an existing library, do not overwrite the existing library during installation of v5.8 but use the option Definitions → Update Library and select the new items to add.

New Features and Enhancements

  • GDA2020 - For Australian users, the Definitions Library has been updated to include the new 'GDA2020' Geodetic Datum and the 'GDA94 to GDA2020' Similarity transformation
  • Evaluation period - The Evaluation period for new un-licensed installations has been increased to 45 executions and 120 days
  • On-line licence registration and Credit card payments - these are no longer available and have been removed from the Geoida website. Registration is available as always through the Help → Registration option where direct EFT is the recommended payment option

Bug Corrections

  • Help → Validation - "Validation has failed !!". Site-licence network validation not detecting valid addresses where VM Adaptor is used - Fixed


New release: Version 5.7 (13 October 2015)


A number of new grid-file formats have been added for the interpolation of geoid undulations/n-values. This now makes it possible to use geoid data in a variety of formats depending on availability, national convention or global location. Both ASCII text and binary formats have been added - most of the ASCII text formats are automatically converted to a binary format for instantaneous interpolation.

New Features and Enhancements

  • Job Configuration - Added numerous formats for selection of geoid grid files containing undulation/n-value data for bi-linear or bi-cubic interpolation
  • Geoid interpolation - Significant speed and other improvements made to the extraction of geoid extents, creation of windowed areas, interpolation etc; progress bars added

Bug Corrections

  • List Points/Export - Alpha names may be truncated or blank - Fixed
  • List/Export Points in Window - "Error 3167 in (Form) Listpts::Sub ListPoints [Source: DAO.Field] - Record is deleted" after a listed point is deleted and points are re-listed - Fixed

  • Definitions library - Corrections to Zone-to-Zone transformations defined in Definitions.gld and Def-UD.gld


New release: Version 5.6 (17 February 2015)


To accompany the long-standing Transverse Mercator projection, version 5.6 now introduces a number of other commonly used projections, namely Lambert's Conformal Conic, Mercator and Oblique Mercator, with variants of each of these to allow for different methods by which the projections may be defined. This will now make the computing of standard projection coordinates possible in most countries of the world.

New Features and Enhancements

  • New projections
    • Mercator - 1 and 2 Standard Parallels, Variants 1, 2 & 3
    • Oblique Mercator - Hotine Variants A and B plus SPCS 1-point version
    • Lambert's Conformal Conic - both 1 and 2 Standard Parallels
  • Least Squares Network Adjustment - Can now plot points listed on Network Points tab (button added)

Bug Corrections

  • Manual Traverse - "Error 3021 in (Form) Traverse::Sub SaveTravPage [Source: DAO.Field] - No current record". May occur in a (multi-page) traverse set when the Delete (record) button is clicked several times to delete any subsequent records, then error keeps repeating on attempting to go back to the previous page - FIXED
  • Alpha-numeric point IDs (Points → AlphaNumeric ID X-Ref) - Database error when saving Description longer than field size - FIXED


Version 5.5.24 (31 July 2014)


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

This update is primarily for attention to issues and bugs with geoid interpolation and their impact on the Import Points, LS Network Adjustment and Job Configuration options, plus attention to a small number of unrelated issues in these and other options.

New Features and Enhancements

  • Geoid extraction
    • Modify or Interrogate Point options 'Interpolate' button - If the point falls outside of an existing grid geoid area, the geoid data will be re-evaluated to attempt to enclose the point, but a subsequent failure will prevent further attempts to re-evaluate the window
  • Zoom Point Range - Entry of invalid point numbers (eg 0 or alpha-numeric) is now prevented
  • Import Points option
    • Will now interpolate geoid values if a model is available and will update an existing model to enclose newly-added points that fall outside the existing window
    • If a geoid model is available, geoid values are interpolated for an incoming point only if they are un-defined but are otherwise retained as imported
    • If the job is set as Geographic (in Job Configuration) now warns if Zone specified is 0
  • LS Network Adjustment option
    • 'Add New Point' button (Network Points tab) now prevents attempt to interpolate geoid for a new point with zero or unspecified coordinates
    • Importing observation data ('Load' button, General tab) - message "nn points fell outside range expected for job" changed to "... fell outside zone defined for job" to clarify meaning
    • 'Compute' - If the "Solution has begun to DIVERGE ..." prompt is displayed but the user accepts results, convergence is assumed and the subsequent "adjustment has not converged - view results" prompt does not appear
    • 'Export' - Added messages to advise if there is no data to export, and that "GNSS observations are NOT exported"
  • Job Configuration option
    • In a job set as Geographic, now tests for an invalid zone number for a normal Transverse Mercator grid when exiting the form
    • The way the 'Apply Geoid' option works has now been changed so that when it is disabled ALL interpolation options are now also disabled. This provides an easy means of switching automatic geoid interpolation on or off as necessary

Bug Corrections

  • Geoid extraction (multiple options)
    • 'Modify Point' in List Points / Export and Least Squares Network Adjustment options: When loading geoid data, progress bar was not shown and message "Error 402 in g_genutil (Form) Progress::Sub Form_Unload - Must close or hide topmost modal form first" was displayed
    • Interpolating geoid values for a point would sometimes display "Selected point falls OUTSIDE of current geoid interpolation window - will re-evaluate ..." but the message would be repeated and the windowed area covered by the geoid file would not be changed
    • Now limits the size of the windowed area to only the maximum required for the job or to the maximum geoid data available, whichever is the lesser
  • Screen display Refresh
    • "Partial range of points" prompt was sometimes displayed
    • Message "Error 6 in Geoida (Module) View::Sub PlotLine - Overflow; Called by: (Module) View::Sub LinesOnOff ..." sometimes occurred when attempting to plot zone boundaries in job set as Geographic but where Projection was set as a project grid (eg PCG94) but the job was located far outside the grid region
  • Import Points
    • When job was set as Geographic and imported non-geographic points were to be converted to geographic and inserted into Enter Points (Lat/Long) table, coordinates were not being converted from grid
    • In a Geographic job, selecting the 'Special' radio button and then a data recorder format would not enable the 'Zone' field
  • LS Network Adjustment
    • 'Add New Point' on Network Points tab - "Cannot find record for new Point 0"; form not loaded to edit new point details - fixed
    • Log file showed "Reading Trimble data file ..." for Topcon and Leica also
    • 'Load' on General tab - When importing points from observation data, points having alpha-numeric IDs were listed in LOG file with "0" for point number - these points now listed with alpha ID
    • GPS Vectors tab, context menu 'Show Obs Details' option: "Error 13 in (Form) LS_Edit::Sub DisplayVector - Type mismatch" - fixed
    • On GPS Vectors tab, copied GPS records would not paste correctly
    • A diverging solution prevented a CSD file being created
  • Delete Window - In a geographic job, deleting by window with the 'Outside' option failed with "Error 3075 in (Form) MainMenu::Sub ProcessPanOrWindow [Source: (Form) MainMenu::Sub DeleteWindow] - Application-defined or object-defined error" - fixed


Version 5.4.18 (20 September 2013)


Bug Corrections

  • Import Points - If a job is Geographic but no points yet exist in the job when a file of points with GRID coords is imported, errors may occur indicating out-of-range latitudes or longitudes - FIXED


Version 5.4.16 (23 August 2013)


Bug Corrections

  • Various options - 'Error 402 - Must close or hide topmost modal form first' on clicking 'Compute' etc
  • Least Squares Network Adjustment - 'Error 91 - object variable or with block variable not set' on 'Re-Load Points' in Network Points tab
  • Job Properties
    • Survey processing options (eg eData, LS Network Adjustment) - Complete geoid file may be read to create windowed geoid file on every 'Compute' (progress bar is displayed); name of new windowed file not saved
    • Incorrect path may be shown on 'Select' for currently-defined geoid file


Version 5.4.13 (21 August 2013)


The major new feature of the new v5.4 release is the addition of a number of new data formats, including TDS/Carlson SurvCE RW5 and various CSV file options for increased versatility for the importation of point data, and both the import and export of observation data for the Traverse and Least Squares Network Adjustment options.
