| Feature | Description |
|---|---|
| Operating System | Microsoft Windows 10 (Pro) |
| Stations per project | 25000 stations can be adjusted per project. We can increase this value at any time. |
| Observations per project | No limit. |
| Bing View | After adjustment. |
| 1D Level and Trig Networks. | Trig networks take into consideration the curvature corrections within the project area. |
| 2D and 3D Local Plane Networks | Support for small network projects usually less than 1km square. |
| 2D and 3D Grid Networks | Both 2D and 3D grid networks are based on the geodetic model. Supports dozens of known zones and allows creation of custom zones. |
| 2D and 3D Geodetic Networks | Both 2D and 3D adjustments are based on the geodetic model. Project span is unlimited. |
| 1D, 2D, 3D Pre-Analysis (Design) | Complete Pre-Analysis for all network types. Simply provide the approximate coordinates for each station, the observation types you will measure and the expected error (expressed as a standard deviation) of these future measured observations. |
| Comprehensive statistics | Coordintate standard deviations and covariance, GPS NEU residuals, distance errors, ALTA uncertainty errors, height errors, error elippses, error ellipsoids and more... |
| Adjust From UI or File | Use the interactive interface to build and edit projects and adjust. Alternatively, create a network adjustment file that describes all parameters for the adjustment. Then, simply load this file and adjust from the Adjust File page. |
| GPS in 2D Networks | Include GPS observations within 2D grid or 2D geodetic adjustments. Columbus automatically takes care of the details. This is a good approach when vertical control is questionable and only 2D results are required. |
| Geoid modeling | Geoid modeling grids included with product. Currently support: NGS Geoid 2012, 2009, 2003, HT2_0 Canada, GSD 95 Canada, EGM 96 and Albuquerque 2008. |
| Deflection modeling | Currently support NGS Deflec 12A. |
| Traverse and loop closures | Perform on-the-fly traverses using existing observations within the project. Fully supports redundant observations between stations. |
| Coordinate inverses | Coordinate inversing is a breeze. All inverse types supported including: azimuths, zenith angles, slope distances, local plane NEU vectors, GPS vectors, and more. All automatically computed when applicable. |
| Coordinate conversions | Convert geodetic to grid and the reverse. |
| Data exporting | Export all coordinate results to comma delimited (csv) files. |
| Import third-party files | Support many current third party formats including: OPUS, Google, Star*Net, Trimble, RW5, RAW, Ashtech, Leica, Topcon and NGS BlueBook. |
