0. TL; DR This algorithm provides a unique identifier for a given coordinate. 1. Introduction Geohash is a latitude/longitude geocode system invented by Gustavo Niemeyer when writing the web service at, and put into the public domain. It is a hierarchical spatial data structure which subdivides space into buckets of grid shape, which is one of the many applications of what is known as a Z-order curve, and generally space-filling curves. Geohashes offer properties like arbitrary precision and the possibility of gradually removing characters from the end of the code to reduce its size (and gradually lose precision). As a consequence of the gradual precision degradation, nearby places will often (but not always) present similar prefixes. The longer a shared prefix is, the closer the two places are. Input (Required) Mode: Encode or Decode. (Required) Latitude: Only required in encode mode. (Required) Longitude: Only required in encode mode. (Required) Geohash: Only required in decode mode. (Optional) Precision: Precision point for encoding coordinates. Output: Geohash for encode mode. Latitude and longitude for decode mode. 2. Example Example 1. Parameter 1: Mode (Encode) Parameter 2: Latitude Parameter 3: Longitude {
 "mode": "encode",
 "latitude": 47.599240004249054,
 "longitude": -122.3333752155304
} Output: {
 "geohash": "c23nb1pt9v2n"
} Example 2. Parameter 1: Mode (Encode) Parameter 2: Latitude Parameter 3: Longitude Parameter 4: Precision {
 "mode": "encode",
 "latitude": 47.599240004249054,
 "longitude": -122.3333752155304,
 "precision": 6
} Output: {
 "geohash": "c23nb1"
} Example 3. Parameter 1: Mode (Decode) Parameter 2: Geohash {
 "mode": "decode",
 "geohash": "c23nb1pt9try"
} Output: {
 "latitude": 47.59923999197781,
 "longitude": -122.33337538316846
