This study set out to evaluate the state of the drought in the Kancheepuram district by means of the VCI and NDVI indexes. Data samples were obtained from the MODIS NDVI database. Group 1 consisted of twenty samples, while Group 2 also consisted of twenty samples. The computations were carried out assuming a beta of 0.2 and a significance level of 0.05, with a 95% confidence interval and G-power 0.8. The water sample did not pose any health risks to humans. Twenty people evaluate the situation using two drought variables: the Vegetation Condition Index (VCI) and the Normalized Difference Vegetation Index (NDVI). For instance, the seasonal rainfall index may display an NDVI of 0.40 along with a VCI of 0.70. This study is considered statistically significant since the p-value is less than 0.05 (or p=0.021). When assessing the drought situation in the Kancheepuram district, VCI yields more accurate results in the seasonal variation index than the NDVI index. [ABSTRACT FROM AUTHOR] |
