Example

A complete example can be found here

from vtzero.tile import VectorTile, Tile, Layer, Point

# Create MVT
tile = Tile()

# Add a layer
layer = Layer(tile, b'my_layer')

# Add a point
feature = Point(layer)
feature.add_points(1)
feature.set_point(10, 10)
feature.add_property(b'foo', b'bar')
feature.add_property(b'x', b'y')
feature.commit()

# Encode mvt
data = tile.serialize()
