geojson 1.0

Encoder/decoder for simple GIS features

This package contains:

• The reference implementation of the Python geo interface:

  http://trac.gispython.org/lab/wiki/PythonGeoInterface

• Functions for encoding and decoding GeoJSON (http://geojson.org) formatted data.

Geojson provides geometry, feature, and collection classes, and supports pickle-style dump and load of objects that provide the lab’s Python geo interface. Here’s an example of a round-trip through the GeoJSON format:

>>> import geojson
>>> p = geojson.Point([0.0, 0.0])
>>> p
Point(coordinates=[0.0, 0.0])
>>> data = geojson.dumps(p)
>>> data
'{"type": "Point", "coordinates": [0.0, 0.0]}'
>>> q = geojson.loads(data, object_hook=geojson.GeoJSON.to_instance)
>>> q
Point(coordinates=[0.0, 0.0])

The geometry classes interoperate with Shapely via the geo interface:

>>> from shapely.geometry import asShape
>>> x = asShape(p)
>>> x.wkt
'POINT (0.0000000000000000 0.0000000000000000)'
