Formula Used

The distance between two points is calculated using the Haversine formula, which accounts for the Earth's curvature:

a = sin²(Δφ/2) + cos(φ1) * cos(φ2) * sin²(Δλ/2)

c = 2 * atan2(√a, √(1−a))

d = R * c

Where:

φ is latitude, λ is longitude
R is Earth's radius (6,371 km or 3,959 miles)
Δφ and Δλ are differences in latitude and longitude

This formula provides accurate distance measurements between any two points on Ontario's road network.
