Hi, great question. No I did not address atmospheric correction in this video as it was more about using the basic raster tools in QGIS. The Sentinel product used in the example was L1C (which is what you get from EarthExplorer). L1C is top of atmosphere (TOA) reflectance with radiometric and geometric corrections. If I was using this product I would instead use the SCP plugin in QGIS to apply the DOS corrections. Alternatively, if I had used SCP in QGIS to download the imagery, which is my normal process, I could access the L2A product which is bottom of atmosphere (BOA) reflectance.
@@spatial-exploration1478 Thank you for the reply! Does the L2A product not need to be corrected? I am new to QGIS and quite like the options for pre-processing but I am still learning about correcting images. I use Sentinel 2 imagery almost exclusively.
This is very helpful. Thank you so much for providing your clear procedure. It works!
Thanks Leslie. Glad it helped. This is just the tip of the iceberg. There is so many multispectral analyses you can easily implement in QGIS. cheers
Great video. All steps explained nicely👍👍
Thanks Sanchi. I appreciate the positive feedback. It makes the time I put in worthwhile. 👌
Great explaination, thank you
Felipe Bastos thanks for the comment 👍
Wow, thank you so much for this
Thanks Cronje. Appreciate it. Good luck with your analysis.
great content keep up the good work !
christopher guth thanks, appreciate the positive feedback mate.
Thank you
Anass AINOUCHE your welcome, thanks for the comment.
Got my like Sir - thanks :)
Rohit Dhankar thanks, appreciate it
Is this imagery already atmospherically corrected?

mantap gan, saya pusing sama metode ini, keep make tutorial NDVI calculation with QGIS
only Kosmos Terima kasih. Are you having problems with anything in particular? Happy to help. Cheers
