| Date | Description |
|---|---|
| November 17, 2019 | Upgrade to .NET 4.7.2. |
| June 6, 2018 | Add Bing maps view after adjustment. Add support for LL records in RW5 files. Improve generation of approximate coordinates. |
| March 6, 2017 | Fix issue after adjustment when reporting output (or csv file creation). Incorrect coordinate type is used (e.g., geodetic coords instead of grid coords). |
| January 29, 2017 | Fix issue where license can change, and not be usable, when connecting to a VPN - (virtual private network). This version will require a new license file. Contact support@bestfit.com for a new license file. |
| January 14, 2017 | More UI improvements, splitter windows and updated preferences usage. |
| January 9, 2017 | Add NGS 12B Geoid and Deflection modeling using bilinear, spline4 and spline6 algorithms. Add splitter window to Adjust page. Add approximate coordinate reporting to aid in trouble-shooting survey data that will not converge to a solution. Improve mark to mark corrections when measuring very steep short shots. Fix interaction between the station and observation grids within the Adjust Page - when stations in the left grid are removed from the network, the corresponding observations in the right grid will be removed. |
| October 31, 2016 | Release version 4.5.3. Add support to save unique Preferences to a file, then later load them into the current project. |
| October 17, 2016 | Release version 4.5.2. Fix range checking feedback in data grids. Fix NGS BlueBook E (covariance) record parsing. Allow negative scale factors for special case projections. |
| March 14, 2016 | Initial release of Columbus 4.5 for the desktop. |
| October 15, 2015 | Increase the number of stations that can be adjusted from 1000 to 25000. |
| March 15, 2015 | Remove 'View Project' tab until work is completed. Shorten the 'data changed' indicator interval. |
| October 19, 2014 | Remove error (during adjustment) when Hor Angle set does not have a Backsight Name AND no horizontal angle was measured. No backsight name needed in this case. |
| April 14, 2014 | Fix out-of-range error handling when entering North and East coordinates. Fix cultural issues for decimal. |
| December 07, 2013 | Remove Project Page and cloud database storage. Enhance Data Page - Columbus Tab for creating/saving projects to disk. |
| October 27, 2013 | Add export button to Project Page. Remove from Tools Page - Export Tab. |
| April 17, 2013 | When using Adjust by File, ensure unsupported keywords read (from file) are displayed in the Adjustment Summary tab. |
| March 16, 2013 | Add support for Network Design (Pre-Analysis). Fix manual reporting and CSV generation after adjustment. |
| February 3, 2013 | Add support for NGS deflection modeling (Deflect12A) for Conus, Alaska, Hawaii, Guam, Puerto Rico and Samoa. |
| January 16, 2013 | Add support for user-definable Stereographic Double projection. |
| October 28, 2012 | Add support for computing several different inverse results (1D, 2D and 3). |
| August 20, 2012 | Added support for NGS Geoid Model 2012 Version A. |
| July 7, 2012 | Added support for NGS Geoid Model 2012. |
| June 19, 2012 | Chi Sqr Test on Variance Factor not performed for 1D networks weighted by distance or number of setups. |
| June 6, 2012 | Added Upload Project option to quickly upload an existing project file to the cloud. |
| May 20, 2012 | Added coordinate values for each station on the Adjust page (Station Select grid). |
| May 9, 2012 | Added support to save the selected traverse (or loop closure) route into the cloud. |
| May 1, 2012 | Added tool for computing 1D, 2D and 3D traverses and loop closures. |
| Mar 5, 2012 | Added tool for transforming geodetic coordinates to/from grid coordinates. |
| Mar 3, 2012 | Additional DB logging. Fix covariance to sd/correlation bug when all covariance elements are zero. |
| Feb 22, 2012 | Added tool for exporting stations (with lat/lon) to a Google KML file. |
| Feb 17, 2012 | Added adjusted inverse reports. Rearranged tabs and order of reports. |
| Feb 11, 2012 | Redesigned the geoid modeling user interface. |
| Feb 7, 2012 | Added sample file selection(s) in Data and Adjust By File pages. |
| Feb 1, 2012 | Fixed coordinate observation count in adjustment summary report. |
| Jan 27, 2012 | Initial release of Columbus 4 (1D, 2D and 3D Network Adjustment Software). |
