The Vegetation Condition Index (VCI) compares the current NDVI to the range of values observed in the same period in previous years. The VCI is expressed in % and gives an idea where the observed value is situated between the extreme values (minimum and maximum) in the previous years.

Thanks for your share! And I have some questions for you. Looking forward to your guidance
Q1. I would Like to generate some TCI, VCI, SAVI, WSVI, TVDI maps for my study region, which is positioned between three Landsat scenes.

Which method suits:
1) compute TCI, VCI, SAVI, WSVI, TVDI for each Landsat scenes and then mosaic or
2) Mosaic bands separately and then performed TCI, VCI, SAVI, WSVI, TVDI
Q2. I only research drought in 1 year (2023), so are the formulas for calculating TCI, VCI, SAVI, WSVI, TVDI different when calculating for 1 period (eg 2008-2023)?

what are you using in ndvi_15, 17 and it the maximum ndvi of the selected date range or season or the average ndvi?

Thank you guys, This video is really helpful,
I have one question that how do you convert the value range -1 to 1 for all the NDVI values?
thanks in advance

This video is very beneficial. I will subscribe. Have one doubt, you are taking 15, 17 and 19 images. If I am taking L5, L7 and L8 images How can I composite all the bands together? Please clarify my doubt

How did you calculate the NDVI value? What is NDVI 19, 15 and 17 ? Do you reclassify the value?
