Geo::Coordinates::Converter - simple converter of geo coordinates
use strict;
use warnings;
use Geo::Coordinates::Converter;
my $geo = Geo::Coordinates::Converter->new( lat => '35.65580', lng => '139.65580', datum => 'wgs84' );
my $point = $geo->convert( dms => 'tokyo' );
print $point->lat;
print $point->lng;
print $point->datum;
print $point->format;
my $clone = $point->clone;
my $geo2 = Geo::Coordinates::Converter->new( point => $clone );
my $point2 = $geo->convert( degree => 'wgs84' );
print $point2->lat;
print $point2->lng;
print $point2->datum;
print $point2->format;
the format and datum of geo coordinates are simply converted. when it is insufficient in the coordinate system and the format of the standard, it is possible to add it easily.
-
new
my $geo = Geo::Coordinates::Converter->new( lat => '35.65580', lng => '139.65580', datum => 'wgs84' ); my $geo = Geo::Coordinates::Converter->new( point => $point );
- lat
set to latitude
- lng
set to longitude
- point
set to Geo::Coordinates::Converter::Point object.
when this is set, neither 'lat' and 'lng' and 'datum' and 'format' options are necessary having.
- datum
set to datum
- format
set to format. it is detected automatically.
- converter
set to converter object. Geo::Coordinates::Converter::Datum can be used by default, and other conversion classes also use it.
- formats
the object of the format is set by the ARRAY reference when using it excluding the formatter of default.
- internal_format
the specification format is set internally. default is degree. when it dose not like on internal format when datum is customized, it use it.
- convert
the geometric transformation is done. after it converts it, Geo::Coordinates::Converter::Point object it returned.
# Examples:
my $point = $geo->convert( grs80 => 'degree' );
my $point = $geo->convert( tokyo => 'dms' );
my $point = $geo->convert( dms => 'wgs84' );
my $point = $geo->convert('wgs84');
my $point = $geo->convert('degree');
