INVESTIGATION OF LAND USE COVER PATTERNS OF SEA SHORE VEGETATION OF KANNUR COAST OF NORTHERN KERALA, INDIA USING GISThangavelu A., Manoj K.1, Sapna K., Jyothin C.K. and Prashanth K.P.
The vegetation cover ratio is an indication of beach stability. A detailed evaluation for the assessment of land use land cover morphology and beach stability was carried out by collecting the seasonal field information. Attempts to generate the LULC maps and investigate change detection analysis over a period of 40 years using Landsat satellite images of Landsat 1-5 MSS of 1979, Landsat 7 TM/ Landsat ETM Plus, and Landsat 8 OLI of 2019 sensor of nominal spatial resolution 30m were used. The satellite imageries to assess shoreline behavior the LULC classification, accuracy assessment and extensive field visit along the coast. It is an important technique to use temporal analysis of beach vegetation. The normalized difference vegetation index and LULC mapping methods were done with the help of GIS. Supervised image classifications of maximum likelihood classifier technique were used in the study. Producers Accuracy and Users accuracy were classified Coconut dominant mixed crop (83% and 71.4%), Water body (86% and 85.71%), Residential dominant mixed buildup (75% and 75%) and Barren land (66.6% and 80%). The study had an overall classification accuracy of 78.26% and kappa coefficient (K) was found in 0.706. Coastal environments display the impact of natural forces and processes on man and also the impact of man on the coastal environment. Recreation activities and exploitation of natural mineral resources are an integral part of the problem and affect in the coastal environment.
