ramshresh / multi2single.py

Created September 14, 2021 06:17 — forked from lptorres/multi2single.py

A simple script that converts shapefiles with multipart polygons into singlepart polygons, and copies the fields of the source shapefile. This script is based on a script by Paolo Corti, found here: https://gist.github.com/anonymous/735330 The original script only converts multipolygons by creating a new feature for each part of a multipolygon. …

	import os
	from osgeo import gdal, ogr, osr
	import sys



	def initFields(in_lyr, out_lyr):
	#Arbitrarily get the first feature
	feat = in_lyr[0]
	#loop over each field

ramshresh / multi2single_inplace.py

Created September 14, 2021 06:16 — forked from lptorres/multi2single_inplace.py

This script is similar to multi2single.py, but it converts the shapefile in place, instead of creating a new shapefile.

	from osgeo import gdal, ogr
	import sys



	def multipoly2poly(layer):
	for feature in layer:
	fid = feature.GetFID()
	geom = feature.GetGeometryRef()
	if geom.GetGeometryName() == 'MULTIPOLYGON':
