# Java Vector Tiles

A java encoder and decoder for vector tiles according to

[Mapbox vector tile spec](https://github.com/mapbox/vector-tile-spec)

## Encode a vector tile

```java

VectorTileEncoder encoder = new VectorTileEncoder();

// Add one or more features with a layer name, a Map with attributes and a JTS Geometry. 

// The Geometry uses (0,0) in upper left and (256,256) in lower right.

encoder.addFeature("road", attributes, geometry);

// Finally, get the byte array

byte[] encoded = encoder.encode();

```

or, specifying the feature id:

```java

VectorTileEncoder encoder = new VectorTileEncoder();

encoder.addFeature("road", attributes, geometry, id);

byte[] encoded = encoder.encode();

```

## Maven
