A high performance library for working with vector tiles.

Provides C++ headers that support rendering geodata into vector tiles and rendering vector tiles into images.

• Mapnik > = v2.2.x: libmapnik and mapnik-config
• Protobuf: libprotobuf and protoc

Vector tiles in this code represent a direct serialization of Mapnik layers optimized for space efficient storage and fast deserialization. For those familiar with the Mapnik API vector tiles here can be considered a named array of mapnik::featureset_ptr whose geometries have been pre-tiled.

For more details see vector-tile-spec.

apt-get install libprotobuf7 libprotobuf-dev protobuf-compiler
apt-add-repository ppa:mapnik/v2.2.0
apt-get update && apt-get install libmapnik libmapnik-dev

brew install protobuf
brew install mapnik

Just type:

make

This builds the protobuf C++ wrappers: vector_tile.pb.cc and vector_tile.pb.h

Then include vector_tile.pb.cc in your code. The rest is header only.

Run the C++ tests like:

make test
