Discrimination and Interpretation of various land cover and land resources can be done using estimation of Normalized Difference Vegetation Index (NDVI) from multi spectral satellite data. This study has been attempted to analyse the changes is coconut growing areas of Coimbatore District in Tamil Nadu using multi temporal images of LISS III and Landsat 8 during 2012 and 2015 respectively Cross tabulation of the two temporal NDVI images were done and it could be observed that around 50 % of the total area remains in active plantation. It is also inferred that, in 1118 ha there is a reduction in NDVI value, which means the presence of unhealthy crop or total reduction in number of coconut trees in these areas. Similarly, in 32653 ha there is an increase in NDVI value which indicates in healthier crop or newer establishment of crop. | NDVI as a tool for analysing changes in coconut growing areas of Coimbatore district of Tamil Nadu India
