Compute the distance between two geographic points (perl code)
use strict;
use warnings;
use Math::Trig;- calculate_distance Computes the distance between two points on the Earth's surface using the Haversine formula.
Arguments:
lat1: Latitude of the first point in degrees
lon1: Longitude of the first point in degrees
lat2: Latitude of the second point in degrees
lon2: Longitude of the second point in degreesReturns:
distanceDistance between the two points in degrees
- convert_distance Converts the distance to the specified unit
Arguments:
distance: Distance to convert
unit: Unit of measurement to convert to ("km", "miles", or "nm")Returns: Converted distance
