# Geohash
[![Build Status](https://travis-ci.org/polmuz/elixir-geohash.svg?branch=master)](https://travis-ci.org/polmuz/elixir-geohash)
Geohash encode/decode implementation for Elixir
## [Documentation](https://hexdocs.pm/geohash/)
## Usage
- Encode coordinates with `Geohash.encode(lat, lon, precision \\ 11)`
```Elixir
Geohash.encode(42.6, -5.6, 5)
# "ezs42"
```
- Decode coordinates with `Geohash.decode(geohash)`
```Elixir
Geohash.decode("ezs42")
# {42.605, -5.603}
```
- Find neighbors
```Elixir
Geohash.neighbors("abx1")
# %{"n" => "abx4",
# "s" => "abx0",
# "e" => "abx3",
# "w" => "abwc",
# "ne" => "abx6",
# "se" => "abx2",
# "nw" => "abwf",
# "sw" => "abwb"}
```
- Find adjacent
```Elixir
Geohash.adjacent("abx1","n")
# "abx4"
```
## Installation
1. Add geohash to your list of dependencies in `mix.exs`:
def deps do
[{:geohash, "~> 1.0"}]
end
2. Ensure geohash is started before your application:
def application do
[applications: [:geohash]]
end
