NAME

Geo::Hex::V3::XS - GeoHex implementation with XS. (c-geohex3 Perl5 binding.)

SYNOPSIS

    use Geo::Hex::V3::XS;

    my $zone = Geo::Hex::V3::XS->new(code => 'XM488276746');

    # or

    my $zone = Geo::Hex::V3::XS->new(lat => 35.579826, lng => 139.654524, level => 9);

    say 'geohex.code:  ', $zone->code;
    say 'geohex.lat:   ', $zone->lat;
    say 'geohex.lng:   ', $zone->lng;
    say 'geohex.level: ', $zone->level;

DESCRIPTION

Geo::Hex::V3::XS is GeoHex implementation.

FUNCTIONS

my $geohex_code = encode_geohex($lat, $lng, $level)

Convert location,level to geohex's code.

my ($lat, $lng, $code) = decode_geohex($geohex_code)

Convert geohex's code to location,level. This location is center of geohex.

my $size = geohex_hexsize($level)

Calculate geohex hex size by level.

METHODS

my $zone = Geo::Hex::V3::XS->new(...)

Create geohex zone object.

Arguments can be:

• code

  Create geohex zone object from geohex code.

      use Geo::Hex::V3::XS;
  
      my $zone = Geo::Hex::V3::XS->new(code => 'XM488548');

• lat/lng/level

  Create geohex zone object from location with level.

      use Geo::Hex::V3::XS;
  
      my $zone = Geo::Hex::V3::XS->new(
          lat   => 40.5814792855475,
          lng   => 134.296601127877,
          level => 7,
      );

$zone->lat

Get geohex center location latitude.

$zone->lng

Get geohex center location longitude.

$zone->code

Get geohex code.

$zone->level

Get geohex level. (0-15)

$zone->size
