Build a MBTiles file from a Mapnik stylesheet.

Project description

Landez builds MBTiles files either from a remote tile service URL or from a local Mapnik stylesheet.

The land covered is specified using a list of bounding boxes and zoom levels.

It uses mbutil from Mapbox https://github.com/mapbox/mbutil at the final stage to build the MBTiles file.

INSTALL

Landez requires nothing but python remote mode (specifying a tiles URL), but requires mapnik if the tiles are drawn locally.

::

easy_install sqlite3

sudo aptitude install python-mapnik

USAGE

Remote tiles

Using a remote tile service (Cloudmade by default):

import logging
from landez import MBTilesBuilder

logging.basicConfig(level=logging.DEBUG)

mb = MBTilesBuilder(remote=True, cache=False)
mb.add_coverage(bbox=(-90.0, -180.0, 180.0, 90.0),
                    zoomlevels=[0, 1])
mb.run()

Please respect Tile usage policies <http://wiki.openstreetmap.org/wiki/Tile_usage_policy>

Local rendering

Using mapnik to render tiles:

import logging
from landez import MBTilesBuilder

logging.basicConfig(level=logging.DEBUG)

mb = MBTilesBuilder(stylefile="yourstyle.xml", filepath="dest.mbtiles")
mb.add_coverage(bbox=(-90.0, -180.0, 180.0, 90.0),
                zoomlevels=[0, 1])
mb.run()
