用于将CSV转换为GeoJSON的Python脚本

import csv
import json

def csv_to_geojson(csv_file, geojson_file):
    features = []
    with open(csv_file, 'r') as file:
        reader = csv.DictReader(file)
        for row in reader:
            # 根据CSV文件的列名，构建GeoJSON的属性
            properties = {
                'name': row['name'],
                'latitude': float(row['latitude']),
                'longitude': float(row['longitude'])
            }
            # 构建GeoJSON的几何对象
            geometry = {
                'type': 'Point',
                'coordinates': [row['longitude'], row['latitude']]
            }
            # 构建GeoJSON的要素
            feature = {
                'type': 'Feature',
                'properties': properties,
                'geometry': geometry
            }
            features.append(feature)

    # 构建GeoJSON对象
    geojson = {
        'type': 'FeatureCollection',
        'features': features
    }

    # 将GeoJSON写入文件
    with open(geojson_file, 'w') as file:
        json.dump(geojson, file)

# 使用示例
csv_to_geojson('data.csv', 'data.geojson')
