我实现了Automated Bulk Downloads of Landsat-8 Data Products in Python | Geology and Python教程中的python代码。
它工作得很好,但我想在日期的基础上检索数据。我甚至修改了一些代码,并尝试了,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)但是它抛出了一个错误:
File "<ipython-input-37-ec27c752ae7e>", line 11
(s3_scenes.acquisitionDate='2019-04-22')
^
SyntaxError: invalid syntax我知道日期格式有问题,但无法解决。
也请向我推荐一些好的教程,以便在Landsat8图像上使用AWS。
当我打印批量列表bulk_list [productId LC08_L1TP_152042_20190422_20190507_01_T1 entityId LC81520422019112LGN00 acquisitionDate 2019-04-22 05:56:08.442691 cloudCover 0 processingLevel L1TP path 152 row 42 min_lat 24.9171 min_lon 66.742 max_lat 27.0339 max_lon 69.0604 download_url https://s3-us-west-2.amazonaws.com/landsat-pds...

即使在我使用(s3_scenes.acquisitionDate='2019-04-22 05:56:08.442691')之后,结果仍然是一样的
