Spaten for Python

This library enables you to work with Spaten files with Python.

Compatible with Python 3.5, 3.6, 3.7 and PyPy3.

Installation

pip install spaten

Usage

Reading Files:

from spaten import File

for feature in File('your_file.spaten', readonly=True):
    # Do something with feature
    print(feature)

Writing Files:

from shapely.geometry import Point
from spaten import Feature, File

with File('out.spaten') as sf:
    sf.append(Feature(Point(6.9, 50.9), {"class": "shop", "height": 12}))

You can also use a stream for reading and writing in one go:

from spaten import File

with File('in_and_out.spaten') as sf:
    for feature in sf:
        if some_condition(feature):
            sf.append(apply_transformation(feature))

It is also possible to read or write from stdin/to stdout, but please note that python opens stdin and stdout in text mode by default, so you need to use sys.stdin.buffer and sys.stdout.buffer:

import sys
from spaten import File

for feat in File(sys.stdin.buffer):
    print(feat)
