Geojson to shapefile using Python
12,181
ogr2ogr appears to be a command line program - to use this you might want to look into something like subprocess.Popen()
:
import urllib, geojson, gdal, subprocess
url= ' http://ig3is.grid.unep.ch/istsos/wa/istsos/services/ghg/procedures/operations/geojson?epsg=4326'
response = urllib.urlopen(url)
data = geojson.loads(response.read())
with open('data.geojson', 'w') as f:
geojson.dump(data, f)
args = ['ogr2ogr', '-f', 'ESRI Shapefile', 'destination_data.shp', 'data.geojson']
subprocess.Popen(args)
EDIT: In response to comments - yes, pickle
is not the appropriate way to go about writing to the file in this case.

I'm trying to convert a geojson file into a shapefile. I'm trying this way (I'm very new to Python so it might be incorrect).
import urllib, geojson, gdal url= ' http://ig3is.grid.unep.ch/istsos/wa/istsos/services/ghg/procedures/operations/geojson?epsg=4326' response = urllib.urlopen(url) data = geojson.loads(response.read()) file = open ('data.geojson', 'w') pickle.dump(data,file) file.close() ogr2ogr -f "ESRI Shapefile" destination_data.shp "data.geojson"
So I'm getting the data from an url, put it in a file and when I try to convert it into a shapefile I got this error:
File "<stdin>", line 1 ogr2ogr -f "ESRI Shapefile" destination_data.shp "data.geojson" ^ SyntaxError: invalid syntax
As I'm quite new I tried the solutions that I found on the web. Is there any way of making this work?

Gus almost 7 yearsWhen I do this, I got another error >> ERROR 4: Failed to read GeoJSON data FAILURE: Unable to open datasource `data.geojson' with the following drivers. -> ESRI Shapefile To be honnest I'm not so sure about my way of getting the geojson. file = open ('data.geojson', 'w') pickle.dump(data,file) file.close()

asongtoruin almost 7 years@Gus you're write - I've edited my response. This does seem to write the geojson data to the file, though I can't test the
ogr2ogr
part unfortunately. -
Gus almost 7 yearsthanks, it's working now. pickle was indeed not the right way.
