pygml 0.2.2

Parsing GML geometries

pygml

A pure python parser and encoder for OGC GML Geometries.

Installation

$ pip install pygml

Features

Parse GML 3.1, 3.2, compact encoded GML 3.3 and GeoRSS geometries to a Geo Interface compliant class.

>>> import pygml
>>> geom = pygml.parse("""
... <gml:Point gml:id="ID" xmlns:gml="http://www.opengis.net/gml/3.2">
...    <gml:pos>1.0 1.0</gml:pos>
... </gml:Point>
... """)
>>> print(geom)
Geometry(geometry={'type': 'Point', 'coordinates': (1.0, 1.0)})
>>> print(geom.__geo_interface__)
{'type': 'Point', 'coordinates': (1.0, 1.0)}

Conversely, it is possible to encode GeoJSON or Geo Interfaces to GML

>>> from pygml.v32 import encode_v32
>>> from lxml import etree
>>> tree = encode_v32({'type': 'Point', 'coordinates': (1.0, 1.0)}, 'ID')
>>> print(etree.tostring(tree, pretty_print=True).decode())
<gml:Point xmlns:gml="http://www.opengis.net/gml/3.2" srsName="urn:ogc:def:crs:OGC::CRS84" gml:id="ID">
  <gml:pos>1.0 1.0</gml:pos>
</gml:Point>
