Why not convert to + (positive) in calculating vegetation proportion like in this way Square(("NDVI1_125" + 0.04842264205217361 ) / (0.509916 + 0.04842264205217361))
Very helpful video. Thanks a lot! I am just wondering whether you made a mistake in the NDVI calculations. You calculated „Band 5 - Band 4“ instead of „+“ in the second part of the NDVI formular at 9:30. So you subtracted B5 with B4 twice. Is it just by mistake and how does it affect the results?
Excuse me, I have a problem generating the BT variable because it gives me temperature range data that is too high and I cannot correct it, it is in lansat 9, I would appreciate some guidance
Very nice video on land surface temperature. Please make LST and NDVI Correlation using R Software ( include Density and scatter plots) video.....Thank you so much sir
Sir, I have analysed forms of soil acidity for 850 surface soil samples. How should I calculate correlationship between my actual data and data from landsat data.
I wanted to apply this video to the LST in Landsat (1984) but I found incorrect results ( Value is beween 78 & 7563). what do you think is the problem? Although I Used Band6 instead of band10, because it is not available in landsat5 (1984) , thanks
Thank you for this helpful tutorial! Just a quick question: is Land Surface Temperature the same as Head Load index? if not, how can I calculate Heat Load index in ArcGIS using Landsat image? Thank you!
Hi, thank you for your great education, I have two question, 1_can I use Landsat collection 2 level 1 data with this method?? and another question : 2_This formula is for landsat 8 "LST = (BT / (1 + (0.00115 * BT / 1.4388) * Ln(ε)))" Do you sure we can use this formula for Landsat 9 too?
Sir LST may vary daily right?? then by considering for a single day landsat data how it is concluded for a year???? For example if we are doing a project on drought vulnerability assessment in that the lst should not be taken for one day right?? For years we need to do at that point of time how we will generate a single lst map ??
Thanks for your video! From my point of view, the calculation would be easier with a level 2 image. After converting from 16 bits to 32 bits you can use this: Band 10.tif * (TEMPERATURE_MULT_BAND_ST_B10) + (TEMPERATURE_ADD_BAND_ST_B10) = LST. Or is there a special reason for not doing so?
The Land Surface Temperature range seems to be on lower side. I have used this method for various regions in India but the LST range always seem to be coming on lower side. I have also compared LandSAT8/9 data result with that of data captured through Drone based TIR camera. This comparison shows vast variance in LST range but of course the High LST region match. Is this a case of Temp. saturation in LSAT 9 data around 50 degree Celsius. Can you explain??
Do you mean you get high LST values with Landsat 9? because it is what is happening to me, in L8 and L9 images of the same year and month, I get higher temperature values with landsat 9, I also want to know what happens
Great & very educative.... thank you sir

how did you get λ= 0.0015 and p= 1.4388? please explain

I also noticed.
Thank you so much, very very useful.

The temperature is high because it is in Kelvin
i think we use float option when calculation NDVI
Exactly! He makes some mistakes in the calculation. How he ends up getting the NDVI image still is beyond me.

Very nice sir ji
Excellent video...
Thank you for your review
Thank You!
You're welcome!
Sir how can we calculate LST from 1 March till 15 May 2021 ??
Please guide
Is atmospheric correction needed?

i have the same problem. landset 9 showing more high number
please sir how can i do for landsat5 and 7. we don't have band 10
Use band 6 for landsat 7 and 4-5
@@shatabdisinha6779 for the rest is it the same thing? I can use the same relationship.
THANKS
