Hurricane Mapping and Damage Assessment Suganya.B B.E(Geoinformatics)- III year Anna Univeristy, Chennai, India Email: sugan_jb@yahoo.com A.Lavanya B.E(Geo-informatics)- III year Anna University Email: lavanya_gi@yahoo.co.in D.Gayathiri B.E(Geo-informatics)- III year Anna University Email: d_gayathiri@yahoo.co.in Hurricanes, or Cyclones as they are called in India, are one of nature‘s most violent manifestations and potentially the deadliest of all meteorological phenomena. It is a unique combination of violent winds with a speed greater than 120 km per hour, heavy rains, mountainous waves and abrupt sea floods. Hurricanes have a life span of 1 to 30 days. The aim of this paper is to analyze hurricane direction, patterns and to quantify the extent of damage caused by hurricane Katrina (August 23 to August 31, 2005) over New Orleans, Louisiana. Using images acquired by NOAA GOES satellite and ancillary data in a GIS, the dynamics of the hurricane are studied. The data obtained from GOES real time satellite (from Imager and Sounder instruments on-board) is of resolution 1 km visible and 4 km infra red of the CONtinental United States in 5 spectral bands. From the multi temporal image of GOES, we thereby track the course of the hurricane and continuously monitor the vigil along the coast. Studying pre and post-hurricane IKONOS imagery of 0.6m resolution, damage to property and the extent of inundation are identified and classified. The zonation maps are presented using GIS software. The work presented gives us an experience in combining the concepts of GIS and remote sensing in the damage assessment of hurricanes.
