Anda dapat menggunakan fungsi bentuk dari Shapely:
from shapely.geometry import shape
c = fiona.open('data/boroughs/boroughs_n.shp')
pol = c.next()
geom = shape(pol['geometry'])
dan MultiPolygon adalah daftar Poligon, jadi
Multi = MultiPolygon([shape(pol['geometry']) for pol in fiona.open('data/boroughs/boroughs_n.shp')])
Contoh dengan salah satu data saya:
# the dictionaries
for pol in fiona.open('poly.shp'):
print pol['geometry']
