A systematic process which aims to reduce the impact or
consequences of any adverse event like, Flood, Earthquake,
Disease etc. It is more then just response and relief.
It is a potential for a natural or Human-Caused event with
negative impacts or consequences.
It is a situation generated by real or imminent occurrence od an
event that requires immediate response/Attention.
It is a natural or human-caused event which causes intensive
negative impact on people, goods, services and/or environment
acceding the affected community’s capability to respond.
An Emergency is a situation in which the
community is capable of coping.
A Disaster is a situation in which the
community is incapable of coping. It is a
natural or human-caused event which causes
intense negative impacts on people, goods,
services and/or the environment,
Better data storage
Better data analysis
Handy in planning
Helpful for stakeholders/ Decision Makers
In digital cartography 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
The specific application in Risk Assessment
are, Hazard mapping to show earthquake,
floods, landslide or fire.
These maps are used for warning system.
In digital cartography GIS application can be
useful in the following activities
To create Hazard inventory maps
Locate Critical Facilities
To help out the peoples
Digital cartography 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.
Representation of High risk areas
Facilitates the implementation of necessary mechanism to lessen the impact.
Identification of emergency areas on the map.
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
Provide accurate information on exact location of an emergency
Time saving during the determination of trouble areas (Quick
Used as floor guide for evacuation routes
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,
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
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
Ability to represent geographical information 2D
It provides the facility to integrate the different
It effectively collect, analyze, manage and
distribute up-to-date information
It is versatile and easy to use for big purposes, but
requires a little training to get individuals
involved in process.
The GIS based database provides better
environment for future planning.
