Thank you very much sir, hopefully your next video can provide more insight into drought monitoring using VCI, TCI, and PCI to find out the SDI (synthetic drought index) using Landsat and Chirps data.

Thanks for the comment, will try to share more in this regard. please check the other drought monitoring tutorials.

Thank you Sir, it's Very helpful.
I need the VCI, TCI, VHI map also of the area for the time period of 01-01-2022 to 31-04-2022, So where I have to change the code , what is the code , can you Sir share please ?

Thanks for your feedback. here is the link of export data: code.earthengine.google.com/df78c05abe272d57f12f94fb1a54d927

​@@amirhosseinahrarigee Thank you Sir, But Sir the export file VCI, TCU, VHI is full blank, it's not showing anything, Kindly check the code, also if I want to show the map in GEE itself, how to do, I tried to add map in GEE but some error is coming, Can you revised the code Sir

[@amirhosseinahrarigee]

@@tanmoymondal27 no it is not. I have checked for my study area and it was not blank. Maybe you are doing something wrong.

[@mohammeda3812]

Thanks a lot for that! That's really useful.
Would it be possible to share the script so we can apply for our study area?

Thanks for your good tutorial
What is the reason that the values ​​of these 3 indicators do not show a good correlation?
I calculated the Pearson correlation

[@amirhosseinahrarigee]

Not necessarily correlated. Because of different nature of each index. You must check the correlation with climatological variables such as precipitation.

[@Preetom-z9x]

Nice tutorial sir, but I am confused that according to VCI formula the max and min NDVI will be previous year but here you used NDVI max min for that year which you wanted to calculate for VCI, how sir??

[@amirhosseinahrarigee]

Hi, yes I am using the statistical operations of whole period of time.

[@Preetom-z9x]

@@amirhosseinahrarigee Thank you very much for your response, but Sir for example I wanted to calculate VCI of 2001, then which year NDVI, NDVI max min should I take?? & where I have to change the code for this formula

how to export this all work to excel and to gis to make maping work and layout ?

[@amirhosseinahrarigee]

use export function: developers.google.com/earth-engine/apidocs/export-image-todrive
