Abstract


The Vegetation Indices (VI) used for estimation of variations in vegetation cover in past decades. The Fraction of vegetation cover was calculated from pre-computed reflectance database based on inversion of PROSAIL model. It was found that the very low and low forest vegetation cover area was dominated with an area of about 104 Km2 and 69.49 Km2 respectively. The very high forest vegetation cover area is very low of about 24 Km2 . The high and medium vegetation cover forest shows intermediate dominance of about 51.74 Km2 and 57 Km2 in area respectively. The result indicates that NDVI, RVI and PSSRA value closely related to forest vegetation cover. Also, in the regression analysis the same was observed as the high relationship is found between FCOVER AND PSSRA (R2 = 68%) followed by NDVI (R2 = 66%) and RVI (R2 = 65%). The low relationship is found in the relationship of FCOVER and MCARI (R2 = 36.7%) followed by DVI (R2 =53.7%) and IRECI (R2 = 59%).

*2016 Journal Impact Factor was established by dividing the number of articles published in 2014 and 2015 with the number of times they are cited in 2016 based on Google Scholar, Google Search and the Microsoft Academic Search. If ‘A’ is the total number of articles published in 2014 and 2015, and ‘B’ is the number of times these articles were cited in indexed publications during 2016 then, journal impact factor = A/B.
