Abstract
We evaluate how information extracted from free remote sensing imagery, using low-cost image processing software and Geographic Information Systems (GIS) can assist with hazard and vulnerability mapping aspects of disaster preparedness. Object-Based Image Analysis (OBIA) by means of Freeware and Open-Source Software (FOSS), in combination with high-resolution virtual globe imagery (such as GoogleEarth and BingMap) was assessed against results derived using commercially available software. Preliminary findings from study areas of the Portsmouth area (UK), the Commonwealth of Dominica (Caribbean) and tsunami-affected districts of Sri Lanka are presented. We make use of freely-available remote sensing imagery and free geoinformatic software to provide an effective and sustainable geoinformatic DRR methodology for coastal regions. This research should help to determine `best practice' for mapping coastal flood hazards and vulnerable features, using moderate resolution optical satellite imagery and digital elevation data.
