Sampel yang Anda kirim menunjukkan bahwa dimungkinkan untuk membagi file secara manual menggunakan editor seperti notepad ++
1) Untuk setiap chunk buat header:
{"type":"FeatureCollection","features":[
2) Setelah tajuk menempatkan banyak fitur:
{"geometry": {"type": "Point", "coordinates": [-103.422819, 20.686477]}, "type": "Feature", "id": "SG_3TspYXmaZcMIB8GxzXcayF_20.686477_-103.422819@1308163237", "properties": {"website": "http://www.buongiorno.com", "city": "M\u00e9xico D.F. ", "name": "Buongiorno", "tags": ["mobile", "vas", "community", "social-networking", "connected-devices", "android", "tablets", "smartphones"], "country": "MX", "classifiers": [{"category": "Professional", "type": "Services", "subcategory": "Computer Services"}], "href": "http://api.simplegeo.com/1.0/features/SG_3TspYXmaZcMIB8GxzXcayF_20.686477_-103.422819@1308163237.json", "address": "Le\u00f3n Tolstoi #18 PH Col. Anzures", "owner": "simplegeo", "postcode": "11590"}},
3) Selesai potongan dengan:
]}
EDIT - Ini adalah kode python yang akan membagi file menjadi beberapa ukuran yang ditentukan (dalam sejumlah fitur):
import sys
class JsonFile(object):
def __init__(self,file):
self.file = open(file, 'r')
def split(self,csize):
header=self.file.readline()
number=0
while True:
output=open("chunk %s.geojson" %(number),'w')
output.write(header)
number+=1
feature=self.file.readline()
if feature==']}':
break
else:
for i in range(csize):
output.write(feature)
feature=self.file.readline()
if feature==']}':
output.write("]}")
output.close()
sys.exit("Done!")
output.write("]}")
output.close()
if __name__=="__main__":
myfile = JsonFile('places_mx.geojson')
myfile.split(2000) #size of the chunks.
