CALCULATION OF LAND CLOSURES

The file name is ENCL. Computer Program. Input requirements: Bearing and distance of each course and when applicable, Radius of each curve. (Delta, length, etc., for curves are calculated by the program). NOTE: This program will not accept Chord lengths of curves. The program will perform "forced closure" calculation. It will also allow all but one side to be held exempt from adjustment. The program will accept several small surveys as independent input and after calculating each, then tie them together into one traverse. An example of this would be when four random traverses are required to establish the four sides of a section, which could result in four "forced closures" and then the result of combining these four answers. Output forms provide copy of the original data, adjusted traverse, error of closure, precision of survey, algebraic sum of Lat. and Dep. and the area in square feet and acres.
