Spatio temporal changes of hudhud cylclone (pre and post Analysis) using GIS technology

Developing countries are vulnerable to tropical cyclones due to climatic variability; climate is likely to increase the frequency and magnitude of some extreme weather and disaster events. Cities and towns situated along the coastal belt in Visakhapatnam district experienced severe damage because of HUDHUD cyclone, which occurred on the 12th of October, 2014; Areas around the city of Vishakhapatnam suffered huge damage. In rural areas, thousands of hectares of agriculture, horticulture plantations and roofs of huts were affected due to high wind speed. Urban and rural areas have suffered a lot of economic loss. The main objective of this research was to identify and quantify the damage to agriculture and vegetation caused by HUDHUD cyclone. In this study satellite datasets acquired before and after the cyclone have been used; image processing techniques need to be carried out to assess the changes of pre and post cyclone. Applying Image classification techniques to assess the damage. Vegetation index techniques are being used with special reference to biomass quantification. Eventually HUDHUD cyclone has done significant damage to the rural and urban areas of Visakhapatnam.
