Java Vector Tiles

Encode a vector tile

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();

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