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 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).
