The spacing of cross-section depends upon the nature of the ground, scale of the map and the contour interval required. But as a general rule: The Degree of Accuracy is half a unit each side of the unit of measure. Although by chance (for example, compensating error) surveys with high order accuracies might be attained without high order precision, such accuracies are not valid. The degree of accuracy obtained in both linear and angular measurement must be the same. The transit can read angles accurate upto.
