I'm having a little trouble with the Python OGR API. What I am trying to do is get all the coordinates of each vertex of the outer ring of a polygon.
This is what I have so far:
import osgeo.ogr import glob path = "/home/woo/maps/" out = path + 'output.txt' file = open(out,'w') for filename in glob.glob(path + "*.shp"): ds = osgeo.ogr.Open(filename) layer1 = ds.GetLayer(0) print layer1.GetExtent() for feat in layer1: geom = feat.GetGeometryRef() ring = geom.GetGeometryRef(0) points = ring.GetPointCount() #Not sure what to do here file.close()
I have heard that you can just
for over the region but that only returns the rings in the polygon, not the nodes.
Anyone able to help.
