Java Vector Tiles

A java encoder and decoder for vector tiles according to Mapbox vector tile spec

Encode a vector tile

VectorTileEncoderencoder = newVectorTileEncoder();
// 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 arraybyte[] encoded = encoder.encode();

or, specifying the feature id:

VectorTileEncoderencoder = newVectorTileEncoder();
encoder.addFeature("road", attributes, geometry, id);
byte[] encoded = encoder.encode();
