Relationship of LST, NDBI and NDVI using Landsat-8 data in Kandaihimmat Watershed, Hoshangabad, India

Normalized Difference Vegetation Index (NDVI) and Normalized Difference Built-up Index (NDBI) have been computed and their relationships with Land surface temperature (LST) in each season were examined. LST retrieved by thermal data analysis represents the spatial and temporal distribution of surface temperature. NDBI is describing the built-up index and NDVI the proportion of vegetation in the watershed. Relationships of LST with NDBI & NDVI were developed in each season. Correlation results of LST & NDBI has shown strong positive relationship i.e. R-2 = 0.991 in Jan.2016, 0.981 in May 2016 & 0.965 in Oct.2016, where as strong negative correlation were found in between LST & NDVI i.e. R-2 = 0.993, 0.992, & 0.911 in each season. Relationship between NDVI & NDBI was also developed and is showing strong negative correlation i.e. R-2 = 0.979, 0.988, & 0.913.
