SURPAC Surveying Software
The Field Traverse Programme, showing intermediate calculations 
Field Traverse Calculations
Calculates and adjusts a series of Traverse Points, using adjusted data extracted from a User defined SURPAC Observation File. 

Each SetUp in the Traverse is oriented using one, or more, interior and/or exterior orientations. The T t corrections are also applied. 

Traverse Distances are reduced for Scale Enlargement, Sea Level, Projection Factor and Slope. Vertical Angles are corrected for Curvature and Refraction. 

If observed, the mean of forward and back distances and vertical height differences are used. 

Traverse may be 2D (Y, X) or 3D (Y, X, Z). 

Three adjustment alternatives are offered to adjust the Traverse misclosure. 

The SURPAC Planimetric Least Squares Adjustment programme may also be used for computing Traverses.
