Disaster (natural calamities) causes enormous destruction to lives and wealth. Disaster produces huge negative impact on a nation’s economy.
It is not possible to recoup damages due to disaster but by proper disaster planning and management we can produce the effect of disaster. This Seminar provides brief knowledge of GIS and its applications in disaster management.
GIS produces a new avenue in disaster planning and management. It also provides efficient measures to encounter a disaster. It also precautionary measures before a disaster and rehabitaion measures.
This paper focuses on use of GIS in rehabitaion of suffered in Bhuj Earthquake.
Role of GIS and Remote Sensing in post disaster scenario The power of GIS and remote sensing can be used to save lives in a post-disaster scenario, by providing decision support in prioritising relief efforts and by helping relief crews get to affected areas in a timely manner.
It can also help provide people made destitute by an earthquake with quicker relief, in the form of relocation planning and quick settlement of damage claims.
Therefore IT and in particular GIS (Geographic Information Systems) combined with remote sensing and image processing opens up new avenues for effective decision support in natural disaster management
The power of a GIS in pre-disaster planning is heightened when these hazard maps are super-imposed with mapping of infrastructure and lifelines. These include mapping of water supply lines, bridges, transportation, telecommunication, and power networks, as well as critical facilities such as hazardous material locations, power generating plants, refineries, ports, etc
The maps generated from aerial photos would provide a spatial coverage of the damaged areas, identifying the worst affected regions to prioritise the relief efforts
