NAME
Geo::Functions - Package for standard Geo:: functions.
SYNOPSIS
use Geo::Functions qw{deg_rad deg_dms rad_deg}; #import into namespace print "Degrees: ", deg_rad(3.14/4), "\n"; use Geo::Functions; my $obj = Geo::Functions->new; print "Degrees: ", $obj->deg_rad(3.14/2), "\n";
DESCRIPTION
CONVENTIONS
Function naming convention is "format of the return" underscore "format of the parameters." For example, you can read the deg_rad function as "degrees given radians" or "degrees from radians".
CONSTRUCTOR
new
The new() constructor
my $obj = Geo::Functions->new();
METHODS
deg_dms
Degrees given degrees minutes seconds.
my $deg=deg_dms(39, 29, 17.134); my $deg=deg_dms(39, 29, 17.134, 'N');
deg_rad
Degrees given radians.
my $deg=deg_rad(3.14);
rad_deg
Radians given degrees.
my $rad=rad_deg(90);
rad_dms
Radians given degrees minutes seconds.
my $rad=rad_dms(45 30 20.0);
round
Round to the nearest integer. This formula rounds toward +/- infinity.
my $int=round(42.2);
dms_deg
Degrees minutes seconds given degrees.
my ($d, $m, $s, $sign)=dms_deg($degrees, qw{N S}); my ($d, $m, $s, $sign)=dms_deg($degrees, qw{E W});
dm_deg
Degrees minutes given degrees.
my ($d, $m, $sign)=dm_deg($degrees, qw{N S}); my ($d, $m, $sign)=dm_deg($degrees, qw{E W});
mps_knots
meters per second given knots
my $mps=mps_knots(50.0);
knots_mps
knots given meters per second
my $knots=knots_mps(25.0);
