将CSV转换为GeoJSON的Python脚本

可以直接使用 geojson 包裹:

import csv, json
from geojson import Feature, FeatureCollection, Point

features = []
with open('CurrentObs.csv', newline='') as csvfile:
    reader = csv.reader(csvfile, delimiter=',')
    for latitude, longitude, weather, temp in reader:
        latitude, longitude = map(float, (latitude, longitude))
        features.append(
            Feature(
                geometry = Point((longitude, latitude)),
                properties = {
                    'weather': weather,
                    'temp': temp
                }
            )
        )

collection = FeatureCollection(features)
with open("GeoObs.json", "w") as f:
    f.write('%s' % collection)

检查此脚本是否解析

import csv
import json
from collections import OrderedDict

li = []
with open('CurrentObs.csv', 'r') as csvfile:
    reader = csv.reader(csvfile, delimiter=',')
    for latitude, longitude, weather, temp in reader:
        d = OrderedDict()
        d['type'] = 'Feature'
        d['geometry'] = {
            'type': 'Point',
            'coordinates': [float(latitude), float(longitude)]
        }
        d['properties'] = {
            'weather': weather,
            'temp': temp
        }
        li.append(d)

d = OrderedDict()
d['type'] = 'FeatureCollection'
d['features'] = li
with open('GeoObs.json', 'w') as f:
    f.write(json.dumps(d, sort_keys=False, indent=4))
