NAME

       Geo::Constants - Package for standard Geo:: constants.

SYNOPSIS

         use Geo::Constants qw{PI DEG RAD}; #import into namespace
         print "PI:  ", PI(), "\n";
         print "d/r: ", DEG(), "\n";
         print "r/d: ", RAD(), "\n";

         use Geo::Constants;                #Perl OO
         my $obj = Geo::Constants->new();
         print "PI:  ", $obj->PI, "\n";
         print "d/r: ", $obj->DEG, "\n";
         print "r/d: ", $obj->RAD, "\n";

DESCRIPTION

CONSTRUCTOR

   new
       The new() constructor

         my $obj = Geo::Constants->new();

METHODS

   PI
         my $pi = $obj->PI;

         use Geo::Constants qw{PI};
         my $pi = PI();

   DEG
         my $degrees_per_radian = $obj->DEG;

         use Geo::Constants qw{DEG};
         my $degrees_per_radian = DEG();

   RAD
         my $radians_per_degree = $obj->RAD;

         use Geo::Constants qw{DEG};
         my $radians_per_degree = RAD();

   KNOTS
       1 nautical mile per hour = (1852/3600) m/s - United States Department of Commerce,
