如何将 Fieldalytics API 检索到的数据加载到 GeoPandas 中？

编程问答 2022-05-17

问题描述

我从 Fieldalytics API 检索了地理边界数据：

y = getBoundary(fieldboundary)
print(y)

({'type': 'polygon','坐标': [[[-109.308557510376,51.5768561748859],[-109.285554885864,51.5768295045241],[-109.285640716553,51.562505259384],[-1509],[-105 51.5624785806018],[-109.308557510376,51.5768561748859]]]},'https://api.efcsystems.com/boundary/ff2bf689-908f-4d17-bd59-183c16758e23?format=geojson&srid=4326&api_partner_guid=...&private_key=...')

然后我尝试将其加载到 GeoPandas 中：

import geopandas
d = geopandas.read_file(y[0])

我收到以下错误消息：
