This is a tiny Java 8 library able to convert [JTS](https://en.wikipedia.org/wiki/JTS_Topology_Suite) geometries to a set of [GeoHashes](https://en.wikipedia.org/wiki/Geohash) with arbitrary precision (<12). 

A GeoHash-based Mallorca discretization looks like:

The precision used is 7 - notice that the GeoHash set is reduced if all children of a certain GeoHash are present.

## Maven:

```xml

    io.github.adrianulbona

    jts-discretizer

    0.1.0

```

## Code sample:

```java

final Geometry geometry = ...

final DiscretizerFactory discretizerFactory = new DiscretizerFactoryImpl();

final GeometryDiscretizer discretizer = discretizerFactory.discretizer(geometry);

final Set geoHashes = discretizer.apply(geometry, 7);

```
