Library to convert a geohash to/from a latitude/longitude point, and to determine bounds of a geohash cell and find neighbours of a geohash.

This is a PHP implementation based on chrisveness/latlon-geohash. More information (with interactive conversion) at www.movable-type.co.uk/scripts/geohash.html.

Usage

use Beste\Geohash; // encode latitude/longitude point to geohash of given precision (number of // characters in resulting geohash); if precision is not specified, it is // inferred from precision of latitude/longitude values. Geohash::encode(float $lat, float $lon, ?int $precision = null) // return { lat, lon } of centre of given geohash, to appropriate precision. Geohash::decode(string $geohash) // return { sw, ne } bounds of given geohash. Geohash::bounds(string $geohash) // return adjacent cell to given geohash in specified direction (n/s/e/w). Geohash::adjacent(string $geohash, string $direction) // return all 8 adjacent cells (n/ne/e/se/s/sw/w/nw) to given geohash. Geohash::neighbours(string $geohash)
