Inquiry about Band Order for Sentinel-2 Data #4

Open joannasta opened 4 days ago

joannasta commented 4 days ago

Hello,

I appreciate the nice work on this project! However, I noticed that information about the wavelengths is not provided. This is why I would like to inquire about the order of the bands used in the Sentinel-2 dataset for Hydro applications. Specifically, I am interested in:

  1. The specific order of the bands.
  2. If there is a script available that indicates which bands are used and in what order. 3.Information on the tools used to stack the bands.

Thank you for your help !:)

Best,

Joanna

We used the Sentinel-2 L2A STAC collection from the Planetary Computer. The bands are: (B01, B02, B03, B04, B05, B06, B07, B08, B8A, B09, B11, B12)

We used stackstac and rioxarray to read and write the images to geotiffs.

Thanks for the answer! It might be helpful to include this information in the README for future users. Clarifying the band ordering there could save others from potential confusion.
