Python intersects_with_index Examples

Example #1

		index = rtree.index.Index()
		for idx, geom in enumerate(geoms):
			index.insert(idx, geom)

Example #2

		for idx, geom in enumerate(geoms):
			index.insert(idx, geom.bounds)

		geomIdx = 0
		self.assertEqual(geometry_snap.intersects_with_index(geomIdx, index, geoms[geomIdx], geoms), True)
		geomIdx = 1
		self.assertEqual(geometry_snap.intersects_with_index(geomIdx, index, geoms[geomIdx], geoms), True)
