Geo::Hash - A Raku bindings for libgeohash

SYNOPSIS

use Geo::Hash;

my $hash = geo-encode(42.60498046875e0, -5.60302734375e0, 5);
say $hash; # OUTPUT: «ezs42»
my Geo::Hash::Coord $coord = geo-decode($hash);
say $coord.latitude; # OUTPUT: «42.60498046875e0»
say geo-neighbors($hash); # OUTPUT: «[ezs48 ezs49 ezs43 ezs41 ezs40 ezefp ezefr ezefx]»

DESCRIPTION

Geo::Hash is a Raku bindings for libgeohash.

SUBS

geo-encode

Defined as:

sub geo-encode(Num $lat, Num $lng, Int $precision --> Str) is export(:MANDATORY)

Encodes given $lat and $lng pair with precision of $precision and creates a hash value.

geo-decode

Defined as:

sub geo-decode(Str $hash --> Geo::Hash::Coord) is export(:MANDATORY)

Decodes given $hash and creates a Geo::Hash::Coord object.

geo-neighbors

Defined as:

sub geo-neighbors(Str $hash --> List) is export(:MANDATORY)

Returns the 8-neighboring positions, where each position is represented as hash code.
