Feature Description
Operating System Microsoft Windows 64 bit versions 7, 8 and 10.
Stations per project 25000 stations can be adjusted per project. We can increase this value at any time.
Observations per project No limit.
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.
