GREAT !please discuss surface reflectance

This is very interesting. But I think the software equal segmented the distance, would you please explain how the fastest route identified? Each segmented distance 1165. is that reasonable to justify? Thanks for your response in advance.

this LST calculation look simple and interesting, but even after many attempts, the final output doesn't give a reasonable range! I wonder where the problem lies....🤔

Excellent! Pls, hv u got any video on LST calculation using raster calculator in arcGIS? I wonder what was the problem, but my output gives me too large value to consider as Celsius whenever I compute that.

have you already made the necessary radiometric and atmospheric corrections or have you worked directly on the Landsat images?

why didn't you convert Sun elevation from degree to radian?

Can I use Radiance_Mult_Band_10 for Band 10

Hi Thanks for this tutorial I would like to know if I can use this atmospheric correction method before calculating LST using band 10 Landsat 8 OLI TIRS

Thank you - it helped me a lot.

Can I contact you? Do you have an email?

Thank you for this useful video.

How to create Table to synchronize the route line. I am missing this step. Can you show me how to get the attribute data on the feature class of B2C

Where did you find ndvi? I couldn't find it in earthExplorer. how did you create it?

What about sea surface temperature ssst estimation

any idea what band combinations are available for planet data?

Thanks Usman! Any idea how to set the intervals of the M value? Mine route just shows five lines, when I need to put 100 points in.

Thanks for your informative videos, please could you do a video on air temperature retrieval

BT = (K2 / (ln (K1 / L) + 1)) − 273.15, this is correct foramula

so goof😉

Hello Usman, Can you make a video on the Split-Window Algorithm as well?

Very helpful. Thank you

this was great and good to know for later use!

thank you very much for this , but i seem to have a challenge with it. after running the analysis for LST I got a temperature range that was very high beyond the normal temperature. what could have caused it? thanks in advance.

did you undertake the atmospheric correction already?

Sir can you kindly guide how to calculate mean LST for each class of LULC

False and Mistechnique.... This is not Atmospheric Correction and Surface reflectance, rather this is TOA only.

2:19 You can use the math tool and subtract the DEM’s , zero value means no sink 4:55 if zoom out and click the last pixel you’ll see the value is close to 60813

Thanks for sharing. The minute is interpolated from Distance, which means every segment has same velocity, how to decide which segment is fastest?

tnanks

*Great Tutorial!!!👍👍👍*

How to prepare Stream Network map?

Sir how to calculate Air temperatures from LST

What does it means in Basin>Value>high&low. Much thanks

Great tutorial

Thank you.

Sir please show for Landsat7

Very Nice. Plz discuss remote sensing and AI.

Is there a book where I can read about hydrology and hydrology modeling and get to properly understand?

How do I cite this methodology?

Thank You so much Usman. I am working on thesis and needed to understand zonal statistics before working on my methodology. This is a good way to start. But my question is, How do I use zonal statistics table to detect net ecosystem exchange of soil organic carbon for MODIS data?

My NDVI range shows a min of -1 and a max of +1, is there some setting I need to change to get the same in decimals?

Bonjour chers amis merci pour tout ce que vous faites, je voudrais que vous m'aidiez au niveau du logiciel ENVI

how you calculated the length of the streams ? please

correct me if im wrong, in the video, you process the Landsat 8 to produce TOA, as far as i know, TOA (top of atmospheric) still includes atmospheric effect on the Landsat, while SR (surface reflectance) excluding atmospheric effect.

Very helpfull video, please what is the best bands combination of land sat 8 for underground water search in desert area ( Tenere desert in Niger for exemple)

Some information would be useful...

While calculating LST the borders of the tile shows much negative value And as my area lies there what can I do to get rid of it?? Can you please help in resolving this issue.

Isn't NDVI value should be within the range of -1 and +1?

Dear sir, can we use these atmospheric correction method for Landsat 5 and 7? Thank you in advance!
