Function/Subroutine Documentation

distance()

pure real(double) function sufr_earth::distance	(	real(double), intent(in)	lon1,
		real(double), intent(in)	lat1,
		real(double), intent(in)	lon2,
		real(double), intent(in)	lat2,
		logical, intent(in), optional	miles )

Compute the distance between two points over the Earth's surface.

Parameters

lon1	Longitude of first location (rad)
lat1	Latitude of first location (rad)
lon2	Longitude of second location (rad)
lat2	Latitude of second location (rad)
miles	Return result in miles if present and True, otherwise return result in kilometres

Return values
