    Have you tried using multiply as the blending mode in the panchromatic band? I tested it over an NDVI and that improved the resolution a lot.

    • @KlasKarlsson
      @KlasKarlsson  2 года назад +3

      Multiply works fine, but for darker images you will have to tweak the settings for brightness, contrast and so on. Addition "adds" intensity and dark parts will not get darker. If you start by making the pancromatic band overall neutral gray, it works the best.

      @@KlasKarlsson ohhh you're right! I did tweaked the saturation and brightness beforehand cause my images were too dark, I thought that was the standard. Thanks for clarifying!

      @@KlasKarlsson does adjusting the brightness, saturation, and/or gamma prior to blending affect the data integrity?
      Specifically, can we trust the intensities that our sensors report at different saturation values?

      @@jacoblandfield2526 changing these settings does not change the data integrity. You can keep changing settings even after you apply blending modes.

    Hi ! How do I get the land surface temperature with a bundle of Landsat 9 data ?

    • @KlasKarlsson
      @KlasKarlsson  2 года назад +1

      Not really possible. The IR/TIR bands do not actually measure absolute temperature. You may want to check out Sentinel-3 and the Copernicus program...
