NDVI Based Assessment of Land Cover Changes Using Remote Sensing and GIS (A case study of Srinagar district, Kashmir)

Normalized Difference Vegetation Index (NDVI) is an index of greenness or photosynthetic activity in a plant. It technique obtaining various features based upon their spectral signature such as vegetation index, land cover classification, urban areas and remaining presented the image. The NDVI differencing method using Landsat thematic mapping images oli was implemented to assess chane from 2001to 2017. In present study, TM 2001 landsat 8 2017 were used extract values. values calculated satellite image year ranges 0.62 -0.41 that shows significant change across whole region its value 0.53 -0.10 .This also for changes use cover. applied according characteristic like at different threshold -0.1, -0.09, 0.14, 0.06, 0.28, 0.35, 0.5. initially computed Natural Breaks (Jenks) classify map. Results confirmed area without vegetation, water bodies, well built up barren lands, increased 35 % 39.67 2017.Key words: Index,land use/landcover,
