#~ linear rings; the first linear ring defines the exterior of the polygon, while
#~ additional rings define "holes" inside the polygon. In this case, we want a
#~ simple polygon with a square exterior and no holes:
linearRing = osgeo.ogr.Geometry(osgeo.ogr.wkbLinearRing)
linearRing.AddPoint(minLon, minLat)
linearRing.AddPoint(maxLon, minLat)
linearRing.AddPoint(maxLon, maxLat)
linearRing.AddPoint(minLon, maxLat)
linearRing.AddPoint(minLon, minLat)
polygon = osgeo.ogr.Geometry(osgeo.ogr.wkbPolygon)
polygon.AddGeometry(linearRing)
#~ Once we have the polygon, we can use it to create a feature:
feature = osgeo.ogr.Feature(dstLayer.GetLayerDefn())
feature.SetGeometry(polygon)
feature.SetField("CIMCODE", cimCode)
dstLayer.CreateFeature(feature)
feature.Destroy()
#~ Notice how we use the setField() method to store the feature's
#~ metadata. We also have to call the Destroy() method to close the
#~ feature once we have finished with it; this ensures that the feature is
#~ saved into the Shapefile.
#~ 4. Finally, we call the Destroy() method to close the output Shapefile:
dstFile.Destroy()
