scala-geohash aims to provide the basic tools to work with Geohashes in idiomatic Scala.

**Basic Usage**

*Encode a point as GeoHash*

```scala

import org.chobeat.scalageohash.GeoHash

val precision = 12

GeoHash.encodeGeohash(-23.12, -12.33, precision)

```

```scala

import org.chobeat.scalageohash.{GeoHash,GeoPoint}

val precision = 12

val p = GeoPoint(-90.0, -180.00)

GeoHash.encodeGeohash(p, precision)

```

*Decode a GeoHash*

```scala

import org.chobeat.scalageohash.{GeoHash,GeoPoint}

import org.chobeat.scalageohash.GeoHash.BoxRange

import org.chobeat.scalageohash.ImplicitConversions._

val geohash = "5667gf"

val ((latW, latE), (lonN, lonS)): BoxRange = GeoHash(geohash).boxRange

val (lat,lon) = GeoHash(geohash).centroid

```

*Get the neighbour of a GeoHash*

```scala

import org.chobeat.scalageohash.{GeoHash,GeoPoint}

import org.chobeat.scalageohash.Directions._

import org.chobeat.scalageohash.ImplicitConversions._

val geohash = GeoHash("gbsuv")

val neighbour = geohash.getNeighbour(North)

```

*Get all the neighbours of a GeoHash*

```scala

import org.chobeat.scalageohash.{GeoHash,GeoPoint}

val geohash = GeoHash("gbsuv")

val neighbourSet = geohash.getNeighbourSet()

```
