Abstract
ArcPad-Based Mobile Mapping in Tsunami Impact Studies Track: Disaster Mangagement and Emergency Response Author(s): Nageswara Rao Kakani, Ashok Dunna ArcPad supported mobile mapping during the rapid response research after the 2004 Indian Ocean Tsunami. It was found versatile in recording the inundation limits and run-up heights at some selected locations along the east coast of India. The mobile mapping units loaded with the pretsunami satellite images (georeferenced and compressed using MrSID) are used to capture the lines marking the landward limit of the tsunami reach. Further, the lines along which cross profiles are taken with the leveling instruments are also captured in the map, besides the sediment sampling points. The study helped in inferring that there is an inverse correlation between the inundation distances and run-up elevations, an important phenomenon in estimating the tsunami impact in different coastal topographic settings. This in turn would be useful in developing tsunami inundation models and planning toward coastal hazard preparedness.
