lib/Geo/MedianCenter/XS.pm  view on Meta::CPAN

an array of arrays of latitude and longitude in decimal degrees and
optionally a weight; C<tolerance>, a number in meters, if the iterative
algorithm improves its approximation by at most this value, the function
will return; C<max_iterations>, the function will return after this
many attempts to refine the approximation. Returns the latitude and
longitude in decimal degrees.

=item haversine_distance_dec($lat1, $lon1, $lat2, $long2)

Computes the distance between the two points using the Haversine
formula in meters. Latitude and longitude are specified in decimal
degrees.

=item haversine_distance_rad($lat1, $lon1, $lat2, $long2)

Computes the distance between the two points using the Haversine
formula in meters. Latitude and longitude are specified in radians.
