Abstract

Natural disaster mitigation is a collective effort of; forecast, assessment, and encouraging the public participation in rescue and damage recovery efforts. This study focused on the rarely addressed aspect, 'the
value of public awareness' in disaster mitigation. The methodology used satellite data and Geographic Information Systems (GIS) to produce semi-real-time 'Media-GIS' contents. The methodology to produce Media-GIS contents is based on, basic fundamentals of GIS, free satellite images, and information extracted from Google Earth. Hence contents carry inherent characters of GIS but significantly different from conventional graphics in media. Also the graphical variables like, size, value, texture, hue, orientation, and shape, were optimized to match with target content users (age group, social group) and medium (print, TV, WEB, mobile), while minimizing the cost. With the news breaks of the disaster, MODIS (250m) satellite data can be extracted in GeoTIFF and KLM (Keyhole Markup Language) formats. The KML file was overlayed on Google Earth, to extract spatial information of the disaster site. Then, in ArcGIS environment, GeoTIFF file can be transferred into Photoshop for production of the graphical image map content. This Photoshop content is suitable to use independently or can be converted to KML files in ArcGIS. The resulted KLM file is the GIS media content for TV, WEB, mobile contents, or for print media, which support to increase the public awareness of the disaster. Two cases studies; Brisbane flood disaster occurred in early 2011 and the ongoing disastrous flood in Bangkok, are presented in the study.
