我从 Python中的 Landsat-8 数据产品的自动批量下载中实现了 Python 代码 | 地质学和 Python教程。
它工作得很好,但我想根据日期检索数据。我什至更改了一些代码并尝试但没有成功。
bulk_list = []
# Iterate through paths and rows
for path, row in zip(paths, rows):
print('Path:',path, 'Row:', row)
# Filter the Landsat Amazon S3 table for images matching path, row, cloudcover and processing state.
scenes = s3_scenes[(s3_scenes.path == path) & (s3_scenes.row == row) &
(s3_scenes.cloudCover <= 15) &
(s3_scenes.acquisitionDate='2019-04-22')
(~s3_scenes.productId.str.contains('_T2')) &
(~s3_scenes.productId.str.contains('_RT'))]
print(' Found {} images\n'.format(len(scenes)))
# If any scenes exists, select the one that have the minimum cloudCover.
if len(scenes):
scene = scenes.sort_values('acquisitionDate').iloc[0]
# Add the selected scene to the bulk download list.
bulk_list.append(scene)
但它会引发错误:
File "<ipython-input-37-ec27c752ae7e>", line 11
(s3_scenes.acquisitionDate='2019-04-22')
^
SyntaxError: invalid syntax
我了解日期格式存在问题,但无法解决。
还请向我推荐一些关于 AWS on Landsat 8 图像的好教程。
当我打印批量列表 bulk_list

即使在我使用(s3_scenes.acquisitionDate='2019-04-22 05:56:08.442691')
结果之后仍然保持不变
