Traverse Adjustment Using Method of Least Squares and Star*Net

Traverse Adjustment Using Method of Least Squares and Star*Net

Please allow me to share as shown in this image the ability of Least Squares Method of finding best fit solution for a data reduction process where linear approach (compass or transit rule) is surely to fail. The power and elegance the Least Squares Method provides enable you to adjust any configuration of control network as you wish. As shown in the figure, traverse adjustment is possible considering the constraints provided by the cross ties. Local to grid transformation and vice versa is done automatically. Great, great tool. A must for every surveyor.

hi Arnel,
Thanks for information...

usually, i use Autocad civil3D for traverse adjustment.
also I've been developing visual basic application for excel (macro) to calculate traverse and levelling net adjustment. I still need a good software such us Star*net to verify calculation result from civil3D or my own program.

if you don't mind

Star*Net is the ultimate in traverse adjustment. AutoCAD Civil 3D also offers Least Squares adjustment engine but is much inferior to Star*Net's capability. Microsurvey should consider porting Star*Net to Windows Mobile device as plug-in to Fieldgenius. Having this realized is a quantum leap for surveyors.
