Application of Remote Sensing and GIS in Disaster Management by Basudeb Bhatta Computer Aided Design Centre Department of Computer Science and Engineering Jadavpur University • Annual Seminar on Application of Remote Sensing & GIS • Conducted by • 21st Century Society for Geospatial Research & Development • 17 April 2015
Introduction Disasters have become an issue of growing concern throughout the world. Disasters have strong negative implications on sustainable development through social, economic and environmental impacts. Remote sensing and GIS tools are highly effective in disaster management planning.
Disaster Management Cycle Disaster management planning is structured around the disaster management cycle model. Courtesy: K. E. Joyce, K. C. Wright, S. V. Samsonov and V. G. Ambrosia
Reduction Planning All measures and planning that reduce the likelihood of a disaster occurring: Risk identification (potential threats) Modifying the hazard process (stopbanks or seawalls) Behaviour modification (prevent development in hazardous areas) Modifying assets at risk (strengthening buildings and infrastructure, raising floor heights)
Readiness Planning All measures to ensure any response to hazards is efficient and reduces hazard impacts: Public education (on hazards and their consequences, how these consequences can be reduced) Training (of emergency planners and responders) Installing monitoring and warning systems Exercising response plans Fostering community resilience
Response Planning All measures to respond quickly and effectively: Coordinated effort (to manage resources, life essentials) Evacuation Relief Search and rescue Needs assessment
Recovery Planning All measures for the restoration: Restoration of lifeline essentials Restoration of resources (forest, water reservoir) Rebuilding of communities Measures to reduce the risk of future disasters (‘Reduction Planning’ again)
RS/GIS and Disaster Management In order to successfully use RS/GIS techniques for disaster management, physical indicators of features or attributes within the disaster management cycle need to be identified. For the identification, selection of appropriate RS imagery is crucial.
Selection of Appropriate Imagery Based on spatial, spectral, temporal and radiometric properties of the image.
