Test program to transcode a GeoJSON tile into MVT using the mapbox_vector_tile library.

test.py

import json
from shapely.geometry import mapping, shape
import sys
from mapbox_vector_tile import encode

geojson = json.load(open(sys.argv[1]))

layers = []
for name, featurecollection in geojson.iteritems():
    features = []
    for f in featurecollection['features']:
        props = f['properties']
        fid = f['id']
        geom = shape(f['geometry'])
        features.append(dict(geometry=geom, properties=props, id=fid))

    layers.append(dict(features=features,name=name))

x = encode(layers)
print len(x)
