Generating 10-meter Land Surface Temperature with Sentinel-2, SRTM, and Landsat in Earth Engine

- Hi geospatial enthusiast!
Just want to share that I have been experimenting on. I make a script that could help you generate higher resolution land surface temperature (LST) using open source data. Previously, the highest LST data we have is the 100-meter or 30-meter is resamples LST from Landsat TIRS instrument.
Script: code.earthengi...
Now, in the script with the help of Landsat LST as label, we could predict what it will look like in 10-meter resolution. Using Sentinel-2 band, indices and its derivatives also Digital Elevation Model (DEM), we extract the raster together with LST.
This extracted value sample then will be assessed to decide which features or bands or variables is the most important (with high R^2 and low correlated with other top features). For this script, only 3 variable are used. Which is B4, dryness, and elevation. The result show a good 0.88 R^2 and Mean Absolute Error of 1.4 Celcius.
This assessment is very limited of course, we don't have a field data but if you want to advanced, continue!
I hope this video can help you on your research, project, or work! Have a good day!
Thank you, you did a great work
thankyou bro
SRTM = NASA
If i apply this to obtain glacier surface temperature
should I account for emissivity of ice
or should I just use the code as is
try both, see the difference
Can you please make a video for lulc supervised classification by using landsat 8 image for multiple years?
Sure. Next time

Thanks
Bagaimana cara melakukan uji akurasi terkait land surface temperature? terima kasih
Agak sulit ini. Perlu data lapangan. Lalu bandingkan.
HOW Can i chaNGE THE CODE TO USE FOR MY AREA
change the geometry
Are all these variables resampled with the same resolution (30 meter for Landsat) mas? Is it important to resampled with the same resolution if i use with a different resolution (MODIS and Landsat)?
Yes, better need to be in the same resolution
Excuse me , I have a Question? I use a equations for water quality like CU Cr No2 no3 BOD cod ... ,
The Question is here that I get this equation from elsevier article , are these equation correct for use remote sensing?
Where do you get the equation?
@@ramiqcomI got equation from article isi
Thank you code nya bang
