The Relationship between NDVI and LST in the urban area of Mashhad, Iran

Vegetation coverage has a significant influence on the land Surface Temperature (LST) distribution. The present report studies the correlation between the Normalized Difference of Vegetation Index (NDVI) and Land Surface Temperature for urban area of Mashhad, using a satellite images from Landsat 5 TM and Landsat 7 ETM+. The objectives of this study are to retrieve the LST and investigate the relationship between LST and NDVI. NDVI is used to examine the relation between thermal behavior and vegetation cover amount. Finally, regression technique is used to obtain the correlation between LST and NDVI. It is concluded that the correlation between NDVI and LST and regression coefficient from NDVI to LST is negative
