Dynamic seasonal analysis on LST-NDVI relationship and ecological health of Raipur City, India

Land surface temperature (LST) is a significant component of the ecological health of any city and the LST is closely related to the normalized difference vegetation index (NDVI). The present study evaluates the seasonal variability of the relationship of LST with NDVI by using a large dataset of La...
