## mapnik-vector-tile

A Mapnik implemention of [Mapbox Vector Tile specification](https://github.com/mapbox/vector-tile-spec).

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

 - Master: [![Build Status](https://travis-ci.com/mapbox/mapnik-vector-tile.svg?branch=master)](https://travis-ci.com/mapbox/mapnik-vector-tile)

 - 0.6.x series: [![Build Status](https://secure.travis-ci.com/mapbox/mapnik-vector-tile.svg?branch=0.6.x)](http://travis-ci.com/mapbox/mapnik-vector-tile)

## Depends

## Implementation details

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

## Building from source

If you do not need to build against an external mapnik, just type:

    make

This will download all deps (including Mapnik) and compile against them.

To build and test in debug mode do:

    make debug test-debug

If you have Mapnik, libprotobuf, and all the Mapnik deps already installed on your system then you can build against them with:

    make release_base

Note: SSE optimizations are enabled by default. If you want to turn them off do:

```

SSE_MATH=false make

```

If building against an external Mapnik please know that Mapnik Vector Tile does not currently support Mapnik 3.1.x.

 - mapnik-vector-tile >=1.4.x depends on Mapnik >=v3.0.14

 - mapnik-vector-tile >=1.0.x depends on Mapnik >=v3.0.11

 - mapnik-vector-tile 1.0.0 to 0.7.x depends on Mapnik v3.0.x (until 3.0.0 is released this means latest mapnik HEAD)

 - mapnik-vector-tile 0.6.x and previous work with Mapnik v2.2.x or v2.3.x

 - You will need `libmapnik` and `mapnik-config` available

 - Protobuf: `libprotobuf` and `protoc`

## Tests

Run the C++ tests like:

    make test
