使用 python 下载 iNaturalist 图像

Question

I am trying to download images form iNaturalist site: https://www.inaturalist.org/home

For this I am using the following site: https://www.inaturalist.org/observations/export

But I would like to download it directly using python script:

import json
from urllib.request import urlopen
import urllib.parse

url = 'https://www.inaturalist.org/observations.json?has%5B%5D=photos&quality_grade=research&identifications=most_agree&captive=false&taxon_id=85553'
response = urlopen(url)
data = json.loads(response.read())
df = pd.DataFrame(data)

Unfortunately its not working as it bring much less images than the expected number. I think I must be doing something wrong. The url used is the one created through the second site I gave adding at the beginning:' https://www.inaturalist.org/observations.json ?'. Any help would be greatly appreciated. Thank you!

It is limited to 100 observations. You can split your query into multiple queries. However, iNaturalist requests that you not export large numbers of queries.
