1. What is Shipping Route Distance?

The Shipping Route Distance is the total nautical distance between multiple geographic points along a vessel's planned route. It's calculated using the haversine formula which accounts for the curvature of the Earth.

2. How Does the Calculator Work?

The calculator uses the haversine formula:

Where:

• \( point_i \) — Latitude and longitude of waypoint i
• \( \text{haversine}() \) — Haversine distance formula
• \( n \) — Total number of waypoints

Explanation: The formula calculates the great-circle distance between two points on a sphere given their longitudes and latitudes.

3. Importance of Route Distance Calculation

Details: Accurate route distance calculation is crucial for voyage planning, fuel estimation, ETA calculations, and optimizing shipping operations.

4. Using the Calculator

Tips: Enter each route point as latitude,longitude pairs (one per line). Example: "35.6895,139.6917" for Tokyo coordinates. The calculator will sum the distances between consecutive points.

5. Frequently Asked Questions (FAQ)

Q1: What units does the calculator use?
A: The calculator returns distances in nautical miles (nm), the standard unit for maritime navigation.

Q2: How accurate is the haversine formula?
A: It provides good accuracy for most maritime applications, though it assumes a perfect sphere (Earth's actual shape is an oblate spheroid).

Q3: Does this account for actual shipping lanes?
A: No, this calculates great-circle distances. Actual routes may differ due to navigational constraints, currents, or political boundaries.

Q4: What's the maximum number of points I can enter?
A: There's no hard limit, but extremely long routes may time out. For complex routes, consider breaking into segments.

Q5: Can I use this for air routes as well?
A: Yes, the calculation works for any great-circle distance, including air routes. The result will be in nautical miles.
