TSUNAMI OF ACEH : The Role of Marine Geomatics for Science and Society

Abstract

The paper was intended to discuss the global-scale tsunami of Aceh from the point of view of geomatic science and for the benefit of people through some textural, slope and height algorithm of three dimensional satellite data (space shutle contur data) capable of distinguishing between flat, hill and mountainous zone of the affected area and hyperspectral (Ikonos data) to the coastal environmental changes. That is to analise the effect of tsunami to the change of the earth surface: vegetation, top soil; infrastructure : road-network, buildings, people-housing/complex (fishermen villages), energy supply network, telecommunication system, etc. * How to mitigate and prevent/avoid for the less destructive effect by means of geomatic mapping on the potential risk of the hazard coastal area by means of flooded area based on height of tsunami wave (10m, 20m etc) models. * Lesson learned of Aceh tsunami : three dimentional data analysis (based on slope algorithm) for coastal zone rehabilitation, town-planning, escape zone, other coastal area mapping and management. * To the near future, the objective of the paper is to introduce, socialization of ‘Potential Risk and Hazard Coastal Area by Tsunami Wave’ to the society and establish some broad knowledge/ priciples for planner (Bappeda and Bappenas), coastal managers to have holistic view in anticipating all possible risk and hazard of coastal area toward the coastal/ oceanic towards a new paradigm required with more emphasis of local caracter of the nearby sea/coastal fetures/geomorphology, also including traditional thinking,way of life of local inhabitants.
