COLUMBUS comes equipped with an extensive set of tools for 1D, 2D and 3D Coordinate Geometry (COGO). The tools can be used for coordinate transformations, coordinate inversing/traversing, modeling geoidal heights and deflections of the vertical, coordinate exporting and more....

COGO

With a click of your mouse, you can define an inverse/traverse route for 1D, 2D and 3D traverse computations and inverses. These tools enhance your ability to find field blunders by giving you on-the-fly, fast access to loop closure and open traverse computations.

GPS Vectors

GPS vectors from several receiver manufacturer systems can be imported into COLUMBUS (Ashtech, Leica, Trimble, Thales, Sokkia and Magellen). You can easily combine baselines from several receiver systems into one network. Baseline data can be uploaded daily and adjusted, or at the conclusion of field work.

Coordinate Transformations

Our powerful coordinate transformation toolkit supports five primary coordinate transformation methods:

Datum to Datum
Geodetic to/from ECEF Cartesian
Geodetic to/from State Plane
Geodetic to/from UTM
Geodetic to/from Local North, East and Up coordinate systems

State Plane coordinate systems supported include any Lambert Single or Double Parallel, Transverse Mercator or Azimuth Equidistant Projection. Zone constants not supported directly can be set up by you and saved for future projects.

Coordinates from overlapping projection zones are easily converted between zones, by first transforming them from one zone to geodetic, then transforming them to the destination zone. Perhaps best of all, coordinates used in transformations can originate from a network adjustment, COGO, input through a text file or input via our powerful Data Management Grids. This allows you to do ad-hoc computations or to transform thousands of coordinates at once.

The COLUMBUS toolkit also supports National Geodetic Survey, EGM96 and the Canadian HT2_0 geoid modeling grid files. Modeling geoidal heights allows you to easily generate elevations for each station in a GPS network.

Finally, the COLUMBUS toolkit provides customizable coordinate exporting to other software systems and the generation of DXF files for use with CAD packages.
