I am trying to return routes from a batch of coordinates to a single location. This is a volunteer project for a local foodbank and I am quite inexperienced in writing code.
Here is what I wrote in Python:
import csv
import openrouteservice
from openrouteservice import convert
client = openrouteservice.Client(key='5b3ce3597851110001cf624863085b996464465cbf0974fe690fc4ef')
with open ('ClientCoordinates10test.csv' , 'r') as csv_coords:
csv_reader = csv.reader(csv_coords)
EXTRA_COORD = (2.23179, 53.464774)
new_csv_coords = []
routelist = []
for line in csv_reader:
new_csv_coords.append(((float(line[0]), float(line[1])), EXTRA_COORD))
coords = (new_csv_coords)
print(coords[0])
routes = client.directions(coords[0])
decoded = convert.decode_polyline(routes['routes'][0]['geometry'])
print(decoded)
routelist.append(decoded)
# create a file to write to
f = open('route.geojson', 'w+')
# write our path to the file
f.write(str(routelist))
However when I try to load the GeoJSON into QGIS I get an “invalid GeoJSON” error. I’m wondering whether I need to write more properties to the GeoJSON? and if so how do I do this?
Any help is greatly appreciated.
