Permissible Error in surveying

• Permissible error in a single horizontal distance should be within 1 in 500, and vertical distance should not exceed 0.1m.
• In open traverse, average error should not exceed 1 in 600 to 1 in 850.
• For sights upto 120m, an accuracy of `1/3000` to `1/10000` is must.
• Closing error in stadia traverse > `0.055 root(P)`, `P` is the perimeter of the traverse.
• Error in closing for elevation varies from `0.08 root(K)` on level ground to `0.25 root(K)` on hilly ground, where `K=` distance in km.
