Open Location Codes are a way of encoding location into a form that is easier to use than latitude and longitude.
They are designed to be used as a replacement for street addresses, especially in places where buildings aren't numbered or > streets aren't named.
Open Location Codes represent an area, not a point. As digits are added to a code, the area shrinks, so a long code is more accurate than a short code.
A location can be converted into a code, and a code can be converted back to a location completely offline.
Based on javascript version from this repo.
Install via composer:
$ composer require bogdaan/open-location-code
Examples:
use OpenLocationCode\OpenLocationCode;
// encode
var_dump(OpenLocationCode::encode(48.41, 34.81));
// decode (return area array)
var_dump(OpenLocationCode::decode("44870000+"));Method OpenLocationCode::decode returns array with following keys:
- latitudeLo, longitudeLo - the coordinates of the lower left corner of the square
- latitudeHi, longitudeHi - the coordinates of the top right corner of the square
- codeLength - decoded length
