查询相交中的 Python API sentinelsat 错误

Question

我在搜索包含特定坐标的图像时遇到问题。我无法让 intersect 函数与 API 一起使用。

我收到此错误消息：

sentinelsat.sentinel.SentinelAPIError: HTTP status 200 OK: Invalid query string. Check the parameters and format.

那么我怎样才能让查询与交集一起工作？

使用的代码：

from sentinelsat import SentinelAPI, read_geojson, geojson_to_wkt
from datetime import date
from shapely.geometry import box, Polygon

api = SentinelAPI('myusername', 'mypassword','https://scihub.copernicus.eu/dhus')

footprint='footprint:"intersects(POLYGON((0 0,1 1,0 1,0 0)))"'

products = api.query(footprint,
                     date=('20180901', date(2018, 9, 3)),
                     area_relation='Intersects',
                     platformname='Sentinel-2',
                     cloudcoverpercentage=(0, 10))

print(products)

#this works  
#api.download_all(products)

知道如何解决这个问题吗？

Answer 1

replace

footprint='footprint:"intersects(POLYGON((0 0,1 1,0 1,0 0)))"'

with

footprint='POLYGON((0 0,1 1,0 1,0 0))'

I don't know if these numbers are just for reference here but there are no results for this Polygon. To see results for another area try

footprint='POLYGON((0 0,1 1,0 1,0 0))'
products = api.query(footprint,
                 date=('20180901', date(2018, 9, 5)),
                 area_relation='Intersects',
                 platformname='Sentinel-2',
                cloudcoverpercentage=(0, 10))

According to official sentinelsat docs, you can select between three different types of area_relation inside your query. I think you should leave footprint only containing the Polygon:

Intersects: true if the AOI and the footprint intersect (default)
Contains: true if the AOI is inside the footprint
IsWithin: true if the footprint is inside the AOI
