The Normalized Difference Vegetation Index (NDVI) is widely used for monitoring‚ analyzing‚ and mapping temporal and spatial distributions of physiological and biophysical characteristics of vegetation (Gitelson‚ 2004). NDVI which is based on different radiation absorption by green biomass in Red and NIR wavebands is widely used for the assessment of the green plant biomass at ground‚ airborne and satellite levels (Marino et al.‚ 2014). Forests in urban stands tend to have lower stem densities‚
