Dear Admin. With honour, First, i have to say thank you for this tutorial video. But, i have a question to you. What is the name of journal, or proceeding, or book that video used to make this tutorial ?? Please, tell to me 🙏
Excellent! But I wonder why my output gives me too large value to consider as Celsius whenever I compute the LST following these steps, one after another. Pls, did u do something to the bands before the lst computation??? 👍
@@salamander5969 okay, I see! But I also notice that the higher values of the LST are around areas with vegetation and Water bodies, while the areas with built-up density have lower values. This in reality shouldn't be true. So, how do I invert the LST values pls? 🙏🏾
@@Wow-oz4ym but there are several factors that could explain this phenomenon: The time of day when the LST data was captured is crucial. Vegetation, such as in green spaces and farmlands, can heat up quickly under direct sunlight but also cools down rapidly after sunset. In contrast, built-up areas tend to retain heat longer due to the urban heat island effect. If your data was captured during midday or early afternoon, it's possible that the vegetation areas were at their peak temperature, while the urban areas had not yet reached their maximum. Check the metadata and find when the data was captured on that date (Scene_Center_Time) and then convert it from UTC to your local time. If it is early morning, then it makes sense.
It will be a great help if you send the document elaborating the process shown in your video. Secondly, is there any solution to saturation temperature being very low in the LANDSAt 8 TIRS data.

Pls Sir, can the same steps be followed for a LANDSAT bands 4, 5 and 10 that are downloaded from USGS C2, L2? I've attempted several times but the high LST value finally was more that 200, and the low value more than 50! That can't be possible
i have seen the tutorial of lst by landsat 8 .it is good ,short and precise sir, please share the LST processing using landsat 5 and landsat 7 thank you for your kind response
I hope you to reply to about this question. In calculating PV, some other learning video insert the min NDVI as minus, although the min value was minus. Which one is right??
Hello sir, please can you elaborate more on the estimation of Emissivity. Which values did you factor in the equation. Are they the same values used for other images?
Hi. Could you explain the formula of the land surface emissivity calculation? The emissivity of representative terrestrial materials for Landsat 8 TIRS Band 10 are constant values, right?
Dear, it is me again. One more question. I got two landsat datasets. One for landsat8- collection 1 level and the other for the collection2 level2. I wonder which one is better for LST? Thanks
Can you please reply to me, i have an issue, my results are not realistic, they are too high, and i suspect that the problem is with the BT its high than normal can you please reply
