Spaten library for Python

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)
