Get all vertices of a polygon using OGR and Python
It depends a bit on your file format and geometry, but in principle the continuation could look like this.
for p in xrange(points):
lon, lat, z = ring.GetPoint(p)
FYI - for a complete code example based on the original question, and a script you can use right away .. see https://github.com/spatialguru/NME/blob/master/ogr_explode.py
I just ran into the same problem. I ended using the ExportToJson function in ogr and then reading the Json string into a dictionary. Using my data and the notation from the original question, this looks like:
import json
...
ring_dict = json.loads(ring.ExportToJson())
ring_dict
{'coordinates': [[-4.94237, 55.725449],
[-4.941922, 55.725585],
[-4.9420024, 55.7252119],
[-4.9422001, 55.7250997],
[-4.9423197, 55.7251789],
[-4.9425472, 55.7253089],
[-4.94237, 55.725449]],
