Exporting imageCollection

[aldotapia]

Hi,

I used to export image collections using this library (before version 1) and now I'm struggling to do the same task again. For instance:

import ee
from geetools import batch

region = ee.Geometry.Point(-71.5, -42.5).buffer(10000).bounds()
col = ee.ImageCollection('COPERNICUS/S2').filterBounds(region)

batch.Export.imagecollection.toDrive(collection = col, folder =  'S2', region = ee.Feature(region), scale=10, dataType='float')

The error message is the following:

EEException                               Traceback (most recent call last)
Cell In[12], line 7
      4 region = ee.Geometry.Point(-71.5, -42.5).buffer(10000).bounds()
      5 col = ee.ImageCollection('COPERNICUS/S2').filterBounds(region)
----> 7 batch.Export.imagecollection.toDrive(collection = col, folder =  'S2', namePattern='{PRODUCT_ID}',region = ee.Feature(region), scale=10, dataType='float')
      9 # batch.Export.imagecollection.toDrive(col, 'S2', region, scale=10, dataType='float')

EEException: Invalid argument specified for ee.String(): None

I have tried different namePattern without success, even using image properties like '{PRODUCT_ID}'. Any hints?

Yes at the moment you need to stick to v0 unfortunately because I didn't had the time to completely back port the batch module. As the previous maintainer left it completely untested, I cannot check it yet. I'm planning on working on it very soon because it's a most wanted feature.

I'll leave this issue open until the batch module get reintegrated into the lib.

[aldotapia]

Oh, no worries. I'll switch back to v0 then. Thank you!

i don't know what you are doing with you imageCollection afterward but in case you analyse it with Xarray, be aware that v1 has a to_xarray method based on Xee package.

[aldotapia]

You made my day. I didn't know about that package. Now, my workflow writes directly to my machine skipping the tedious Google Drive folder download step:

import ee
from geetools import batch
import xarray as rx
import rioxarray

region = ee.Geometry.Point(-71.5, -42.5).buffer(10000).bounds()
col = ee.ImageCollection('COPERNICUS/S2').filterBounds(region)

ds = col.geetools.to_xarray(n_images=20, mask_and_scale=False, crs='EPSG:32719', scale=10, geometry=region)
# save a test file
ds['B2'].transpose('time','Y','X').rename({'X': 'x', 'Y': 'y'}).isel(time=-1).rio.to_raster('test.tif')

Thank you!
