Project Description

A framework for writing [tile-reduce](
map scripts in Python.

NOTE: This library is experimental and under active development. No official
release has been created.

First read the documentation at [tile-reduce](

`tile-reduce-py` allows you to write the map script in Python. The reducer is
still Javascript.

import mapbox_vector_tile

import tilereduce

class BuildingRoadCount(tilereduce.TR):
def mapper(self, x, y, zoom, data):
if data is None:
return 0

# Decode the raw binary protocol buffer data
td = mapbox_vector_tile.decoder.TileData(2048)
tile = td.getMessage(data)

count = 0
if tile.get('buildings'):
count += len(tile['buildings'])
if tile.get('roads'):
count += len(tile['roads'])

return count

if __name__ == '__main__':

The reduce script is identical as the original Node example except the `map`
argument is now the path to the Python map script.
