Method Details

### __new__ (cls, lat_ghll, lon=None, precision=None, eps=2.220446049250313e-16, **name) Static Method |
New Geohash from an other Geohash instance or geohash `str` or from a lat- and longitude. Arguments: `lat_ghll` - Latitude (`degrees90`), a geohash (Geohash, `str`) or a location (`LatLon`, `LatLon*Tuple`). `lon` - Logitude (`degrees180)`, required if `lat_ghll` is `degrees90`, ignored otherwise. `precision` - The desired geohash length (`int` 1..12) or `None` or `0`, see encode. `eps` - Optional inference tolerance (`degrees`), see encode. `name` - Optional `name=NN` (`str`). Returns: a new object with type S, a subtype of T New Geohash. Raises: `GeohashError` - Invalid `lat_ghll`. `RangeError` - Invalid `lat_gll` or `lon`. `TypeError` - Invalid `lat_ghll`. Overrides: object.__new__

### adjacent (self, direction, **name) |
Determine the adjacent cell in the given compass direction. Arguments: `direction` - Compass direction ('N', 'S', 'E' or 'W'). `name` - Optional `name=NN` (`str`) otherwise this cell's name, either extended with `.D`irection. Returns: Geohash of adjacent cell (Geohash). Raises: `GeohashError` - Invalid geohash or `direction`.
