GIS in Disaster Management

The document discusses the role of geographic information systems (GIS) and information technology in disaster management, preparedness, and risk assessment. It explains that GIS allows effective storage, manipulation, and analysis of spatial and non-spatial data to create hazard maps, locate critical facilities, and conduct vulnerability assessments. The document also outlines how GIS can support planning, mitigation, preparedness, response, and recovery efforts during disaster management.

 GIS is a tool that allows users to create interactive
queries (user created searches), analyze the spatial
information, edit data, maps, and present the results of
all these operations.
 GIS provides environment for effective and efficient
storage and manipulation of remotely sensed or other
spatial and non-spatial data types for both scientific
management and policy oriented information.
 The specific application in Risk Assessment
are, Hazard mapping to show
earthquake, floods, landslide or fire.
 These maps are used for warning system.

 GIS application can be useful in the following
activities
 To create Hazard inventory maps
 Locate Critical Facilities
 Create and manage associate related
database
 Vulnerability Assessment

 Planning
GIS is useful in helping with forward planning. It provides the framework
for planners and disaster managers to view spatial data by way of computer based
maps.
 Mitigation
 Representation of High risk areas
 Facilitates the implementation of necessary mechanism to lessen the impact.
 Preparedness
 Identification of emergency areas
 Positions of related departments, Agencies, and Human Resources
 Make it easier for security and shelters provides to plan the strategies
 Answer that who is to be based where and at what phase of emergency

 Response
 Provide accurate information on exact location of an emergency
situation
 Time saving during the determination of trouble areas (Quick
Response)
 Used as floor guide for evacuation routes
 Recovery
 Mapping level of damage
 Information related to disrupted infrastructure, number of persons
died or injured and impact on Environment.

 GIS can be used by shelter operators to
capture specific personal details of persons
being housed at the shelters.
 It would make it possible to assess the number
of needed shelters and the structure of that
suffering population like, children, adults,
disables etc..

 In affected areas during and after disaster,
Food Drops is always likely to take place.
 This process can be helped with GIS as maps
can be generated which identify the specific
areas with clusters of victims are located and
the unique need of persons within these
clusters.

 The data is gathered for the analysis and to
assess the need of activities and actions
before, during and after the disaster.
 By the use of this data, maps of most
vulnerable areas can be produced and those
areas can be highlighted which are most prone
to disasters.
