Vector tiles producer

This is an experimental project to create vector tiles.

What does this do?

This creates vector tiles based on the mapnik proto for a given area at chosen zoom levels. The produced geometries are clipped at the limits of the tiles.

Dependancies:

mapnik

mapnik-vector-tile

Install and compile

Install Mapnik. <https://github.com/mapnik/mapnik>

Get mapnik-vector-tile sources. <https://github.com/mapbox/mapnik-vector-tile> Go to Mapnik-vector-tile directory and:

make

Then:

export MAPNIK_VECTOR=path/to/your/mapnik-vector-tile/sources

The sources directory should also contain the vector_tile.pb.cc and vector_tile.pb.h (they are generated when doing "make").

And

make create

to compile the project.

Use it!

Chose a tile (for the whole world: z=0, x=0, y=0). This is the area for which you want to create subtiles until the maxz zoom level. Give then a path to your Mapnik stylesheet (xml). If you want compressed PBF tiles, add the --compress option, else you will get uncompressed PBF tiles.

./create_tiles z maxz x y [--compress] path/to/stylesheet

To get informations about the created tiles, I have modified a bit the Mapnik-vector-tile's "tileinfo" example to read easily the informations of a vector tile.

make tileinfo
