Preview sunglint correction (deglint) in Google Earth Engine

Check out the full version of the tutorial: kzbin.info/www/bejne/lYeTiWSCmbinl5Y. The source code is available here: lynk.id/geografif/LOQjl59.

Why did you use TOA instead of Surface Reflectance Sentinel 2?

[@geografif]

The paper (Hedley et al. 2005) in which this method based on implies that correction level doesn't really matter. Even raw DN can be used.

[@PriparaHiga]

@@geografif ooh that is cool. Thank you for the clarification 💖

[@acinad4605]

can you make a tutorial on how to perform ndvi and supervised class using planet data in arcgis (from corrections, clipping, mosaicking more than 1 scenes to maximum likelihood)

[@geografif]

I don't do Arcgis sorry

[@xiaobozhu3408]

Hello, is it better to change the Hedley et al. (2005) reference band from near infrared to short wave infrared? Can I just change it?

[@geografif]

Hi, several deglint algorithms has been proposed out there in which band beyond NIR is used. So technically yes it is possible. Most sensors only have visible and NIR during the period when the paper was published, hence NIR was used.

Does dii work?

[@geografif]

It should be, but haven't had time to write the script yet

[@PriparaHiga]

@@geografif ooh alright. Looking forward for the dii. Thank you so much for script 💖

[@zephana7631]

What would you recommend doing sun glint correction first or doing the atmospheric correction first?

[@geografif]

I would do atmospheric correction first

Is it possible to get the rest of the code? Thanks! 😀

Halo mas, selamat siang. aku izin nanya, aku juga lagi nyoba koreksi sunglint tapi kalo aku pake SNAP. nah, aku mau nanya ada ga sih caranya biar nyamain warna citra yang sudah melalui proses deglint dan juga citra natural colornya? atau memang harus diatur sendiri lewat color manipulation ya mas? Terima kasih

[@geografif]

Halo. Iya, bisa disamakan nilai minimum dan maksimum dari tiap band untuk visualisasi sebelum dan sesudah koreksi
