field measurements and obtaining accurate coordinates. Columbus uses the geodetic model With Columbus, you can perform 1D, 2D and 3D adjustments using geodetic, grid or local... coordinate systems. Many 3D-type observations can be used in 2D and 1D adjustments. Columbus uses the geodetic model to eliminate mathematical distortions of both small and large...; the zenith and slope distance standard deviation are automatically propagated to the new height difference observation. 2D adjustments are performed in 3D space and can be computed...

Traverse tab This is perhaps the most powerful tool on the Tools page. From this tab, you can calculate loop closures, open-ended traverses or simple side shots for 1D, 2D and 3D..., Columbus 4 automatically knows which observations are applicable, based on the traverse type. Observations can be deselected by un-checking their check box. For 2D traverses, you can... can use either orthometric or ellipsoidal height. 2D inverses can be based on current station heights (orthometric or ellipsoid) or by entering an average height. 1D Height...
