NAME

Geo::Hash::Grid - Make a grid based off of GeoHashes

VERSION

Version 0.08

SYNOPSIS

Sometimes you need a simple grid to cover a geographic area. This is a pretty easy way to get one that covers a geographic box and with a little spillover.

This module inherits from Geo::Hash::XS and subclasses all it's methods.

    use Geo::Hash::Grid;
        
    my $grid = Geo::Hash::Grid->new(
        sw_lat    => $south_west_latitude,
        sw_lon    => $south_west_longidude,
        ne_lat    => $north_east_latitude,
        ne_lon    => $north_east_longitude,
        precision => 8,
    );
        
    my $hash_count   = $grid->count;
        
    my $geohash_list = $grid->hashes;
        
    my $origin_list  = $grid->origins;

METHODS

new

Create the geohash grid that fits in a bounding box and specify the grid size.

  • sw_lat => $decimal_degrees

    Latitude of the southwest corner of bounding box

  • sw_lon => $decimal_degrees

    Longitude of the southwest corner of bounding box

  • ne_lat => $decimal_degrees

    Latitude of the northeast corner of bounding box

  • ne_lon => $decimal_degrees

    Longitude of the northeast corner of bounding box

  • precision => $integer

    Geohash precision

count

Get count of GeoHash's in bounding box

hashes

Get array reference of GeoHash's in bounding box

origins

Get list of hash references of GeoHash lat/long origins in bounding box

bboxes

Get a list of bounding boxes for each hash in the grid
