[ TEST DATA ] : Bands are not Always 192
Data · 22 May 2021, 14:17 · edited ~3 hours later · 7

Hello @KarimAmer

you've mentioned in this discussion :

Added a separate folder with Sentinel-2 images for data points originally captured in 2015. These new images have 192 channels as the rest of the images.  

But, I Faced this problem with Test Data.

In fact there is around or more than 100 Images with 112 bands2015 test images with 112 bands and they don"t exist in sentinel_for_points_collected_in_2015.zip

Please can you clarify this?

Maybe I can clarify? I had a similar question some time ago, but since then I believe the data has been corrected and all spectral images, also in test, should now have 192 channels. I am faily sure that if you correctly updated your data all will now have 192 bands. Maybe just double check that you have the latest data.

There are 49 samples with only 112 bands in test data and I can't find them also in the sentinel 2015 folder .

Hi ASSAZZIN,

Thank you for pointing this out.

The additonal sentinel images are fixed and updated in the new file "sentinel_for_points_collected_in_2015_updated.zip"

Now all the Test Data should have sentinel images with 192 bands.
