在Python中,你可以使用`pandas`库处理CSV文件,并结合高德地图的API来批量获取经纬度和地址信息。首先,你需要安装高德地图的Python SDK(如`geopy`或`pyamap`),然后按照以下步骤操作:
1. 安装必要的库:
```bash
pip install pandas geopy requests
```
2. 导入所需模块:
```python
import pandas as pd
from geopy.geocoders import Geolocator
from geopy.exc import GeocoderUnavailable
import requests
```
3. 创建一个函数来调用高德地图API:
```python
def get_location(address):
try:
# 使用geopy的Geolocator服务
geolocator = Geolocator()
location = geolocator.geocode(address)
return (location.latitude, location.longitude) if location else None
except GeocoderUnavailable:
print(f"无法获取 {address} 的位置")
return None
def batch_get_locations(file_path):
locations_data = []
df = pd.read_csv(file_path)
for index, row in df.iterrows():
address = row["Address"] # 假设CSV列名为"Address"
location = get_location(address)
if location:
locations_data.append((row['Address'], location))
return locations_data
```
4. 调用函数并保存结果到新的CSV文件:
```python
def save_to_csv(locations_data, output_file):
headers = ['Address', 'Latitude', 'Longitude']
data = [headers] + locations_data
df = pd.DataFrame(data, columns=headers)
df.to_csv(output_file, index=False)
input_csv = "input_addresses.csv" # 输入的包含地址的CSV文件
output_csv = "output_locations.csv" # 输出结果的CSV文件
locations = batch_get_locations(input_csv)
save_to_csv(locations, output_csv)
```
在这个例子中,`input_addresses.csv`文件应该包含一列叫做"Address"的数据,程序会读取每个地址,尝试获取其经纬度,并将结果添加到`output_locations.csv`中。
