Traverse Misclose Calculator
Computes the linear traverse misclose from summed departures and latitudes for closure checks.

Before you rely on this: First-pass guide only. Verify safety-critical or regulated work against the relevant standards, your project requirements and a qualified professional.
How to use this calculator
- Enter the sum of departures (ΣΔE) and the sum of latitudes (ΣΔN).
- Press Calculate.
- Read the linear misclose and its bearing.
How it works
Linear misclose = √(ΣΔE² + ΣΔN²). For a closed traverse the sums should be near zero; the result shows how far the traverse fails to close.
Worked example
ΣΔE 0.04, ΣΔN −0.03. Misclose 0.05 m.
Frequently asked questions
What's an acceptable misclose?
Express it as a ratio of the perimeter (see the closure-ratio tool) — e.g. 1:5,000 or better for many jobs.
