Description

Natural hazards, grouped into geophysical (e.g. earthquake, wildfire, flood) and biological (e.g. insect infestation, flu epidemic) categories, have a catastrophic impact on our environment with increasing socioeconomic cost. Both operational and scientific disciplines have the intention of building more resilient communities, which requires improved data collection and analysis. Thanks to the recent advances in remote sensing technique, there is a significant increase in natural hazards related studies from all over the globe, revealing an urgency of our contemporary society. Such work is progressing as the current studies not only apply multiple sophisticated and innovative sensors (ranging from optical, microwave, SAR, and LiDAR) but also develop new methods to combine data of different imaging mechanisms and sources (e.g., in situ measurements and volunteered geographic information). Nevertheless, challenges are to build a real-time observation network for various hazards, to design effective and efficient decision-making system, to maintain resilient districts even in disaster prone area, and so on. On the major theme of ‘Hazard, Geography, and GIScience’, this session invites papers focusing on remote sensing methods and applications pertaining to natural hazards mapping and management. Prospective topics could include but should not be limited to:

• Hazard characterization and modelling with multiple remotely sensed data (especially multispectral, SAR and LiDAR), product and analysis
• Image registration, correction, and fusion for near real time hazard observation, aiming at improved temporal and spatial resolution
• Multi-temporal and spatial analysis for hazard management, including preparedness and response
• Image classification and change detection for hazard monitoring and early warning
• Accuracy assessment and uncertainty analysis for hazard mapping and modeling
• Combination of remote sensing and other sources, such as in situ measurement (gage station), volunteered geographic information (social media and crowdsourcing), and climate model
• Ecological and socioeconomic response to natural hazards of different temporal and spatial variability
