2Introduction
- GIS technology is increasingly being used in
decision support systems. - In the past few years, GIS emerged as a powerful
risk assessment tool and is being put to use to
assess risk to property and life stemming from
natural hazards such as earthquakes, hurricanes,
cyclones and floods.
3Introduction
- Manipulation, analysis, and graphic presentation
of the risk and hazard data can be done within a
GIS system, and because these data have
associated location information which is also
stored within the GIS, their spatial
(3D)interrelationships can be determined and used
in computer based risk assessment models by
government planners for better disaster
preparedness.
4Use GIS in Natural disaster Scenario
- A fundamental principal of Risk Assessment is
that risk due to natural catastrophes such as
earthquakes, hurricanes and flood, is location
dependent, and that it can be assessed within an
acceptable range of uncertainty if reliable
historical and location specific data is
available.
5Use GIS in Natural disaster Scenario
- For e.g. a location which is surrounded by
seismic faults and has a weak surface geology has
a higher hazard potential than a location for
away from faults and with strong surface geology. - Similarly, hurricane, hazard at a location near
the coast and with a flat, bare terrain is far
higher than at a location etc. - Hence with help such data early safe evacuation
are planed executed
6Preplanning -DMP inputs
- GIS in conjunction with remote sensing and
photogrammetry, can be used to identify hazards.
Seismic faults and flood prone areas can be
identified by scientists using GIS to analyse
satellite image, aerial photos and field survey
data.
7Preplanning -DMP inputs
- Once the hazards have been identified, their
representation can be stored conveniently in GIS
databases. - For hurricane risk, information on land use, land
cover, coastline and distance from coast are
important. Similarly topology data is required
for flood assessment and storm surge analysis.
8Preplanning - DMP inputs
- Inventory data can also be stored easily in a GIS
database. Data on building stock, liveliness,
utilities, etc. can be aggregated into manageable
gographic regions such as census wards, pin
codes, or larger administrative regions such as
villages, talukas, and even districts. - Using statistical functions available in GIS
systems, the average value of various properties
of different building classes can be computer
(e.g. average monetary value of residential
dwelling in particular village) and stored with
their corresponding geographic regions in the GIS
database.
9Preplanning - DMP inputs
- The information retrieved by querying the GIS
database serves as inputs for the risk assessment
models. - These risk assessment models can run both
deterministic as well as probabilistic risk
assessment. - It helps computing the damage associated with
that event, - THUS GIS GOES LONG WAY In CONTOL ASSESMENT OF

10Disaster preparedness programme in Andhra
- Now, the Andhra Pradesh State Remote Sensing
Applications Centre (APSRC) has developed a
remote sensing application to overcome some of
the problems that the state faces. The
application areas include surface water, ground
water, marine resources, geology and mines,
energy, agriculture, soils, urban planning,
roads, forestry, animal husbandry and
environmental hazards. Its base is GIS - Also similar plan is developed in Maharashtra
Mumbai
11GIS usage in Industry emergency planning
- Fire , law /security enforcement, and medical and
public health divisions needs to prepare
comprehensively for attending emergencies - Traditionally, first responders have relied on
experience, practiced skills, good equipment, and
teamwork for effective and successful emergency
response - But to respond to large-scale catastrophic
emergencies which common today the traditional
methods need to be supported by technology and
this need can be achieved through GIS .
12GIS use in Industrial fire emergency
- As industrial complex expands for better response
more personnel, stations, and equipment are
purchased - Today response-related investments must also
invest in better planning, evaluation, and data
communication tools and technologies such as
geographic information system (GIS)technology. - This approach will ensure better utilization
available resource and in consequence reduction
13GIS use in Industrial fire emergency
- Effective planning for response involves
understanding how to minimize consequences of
emergencies and acquire the information and data
necessary to respond. - Depending on the nature of the emergency, every
first responder requires certain equipment and
personal protection gear. - Increasingly today , fire responders will also
require the best data and information relevant to
the risks to which they are exposed. - Knowing where critical assets are located and
having first access to key data and information,
response can well planed executed ,this can be
addressed through the purposeful implementation
of GISdigital (or geospatial) data
14GIS use in Industrial fire emergency first
responder
- GISdigital (or geospatial) data Information will
be useful from the moment an emergency call is
received and all that you have do is to punch in
data of the location it would answer the
following questions - What is the best route?
- Where are the closest hydrants?
- What is the layout of the facility?
- What is the occupancy type, and how many people
may need rescue or evacuation?
15GIS use in Industrial fire emergency first
responder
- Beyond maps, other information and data suplied
may include - Photographs of the facility
- Floor plans and main utility control panels
- Existing fire protection systems
- Inventory of the facility (hazardous materials)
- Pre-incident plan (a pre-inspection and fire
protection plan) - Previous call history
16GIS use in Industrial fire emergency Emergency
controller
- GIS data and information will also support rapid
decision making including the following - What additional exposures or facilities are
threatened by this event? - Where should incoming units be positioned to
access critical hydrants that will effectively
support the mission? - If an equipment staging area or incident command
post is required? - where are parking lots, schools, churches,
malls, or other suitable facilities located?
17GIS use in Industrial fire emergency Emergency
controller
- If helicopter evacuation of victims is required,
where are suitable landing sites? - If medical triage or decontamination is required,
what facilities are closest and available? - If hazardous materials are involved or a chemical
plume is being generated, in what direction will
it drift, what is likely to be threatened, and
what is required in protecting and evacuating the
public - If an explosion has occurred or is eminent, who
needs to be evacuated and where are the closest
evacuation facilities and resources?
18GIS use in Industrial fire emergency Emergency
controller
- All of these decisions require geospatial
information (maps, directions, building layouts,
etc.), and most will be in different places and
digital formats GIS helps to combine them . - The GIS can provide first responders the right
information, at the right time, and in the most
relevant place easy to access and use. Data
inter-operability is one of the greatest values
of a GIS, - since GIS can integrate disparate information and
provide useful visual information quickly to
first responders.
19GIS use in Industrial fire emergency Emergency
controller
- GIS can also create various scenarios through
spatial modelling that produce visualization that
can more accurately and realistically describe
the direction and extent of explosions, plumes,
fire behaviour, or disease outbreak. - For example, instead of guessing or estimating
evacuation requirements, transportation network
delays, or blockages, GIS can provide an actual
prediction of the scale of the event and visually
display potential consequences.

26Summary
- First responders require effective physical
tools, as well as intangible information tools,
to evaluate and manage risk and, at the same
time, increase their overall capacity for
effective response. - Fire-fighters, should adopt of information
technologies, such as GIS, that both increase
capacity and leverage existing informational
resources toward prevention and preparedness. - Complex incidents involving multiple agencies and
private organizations require the ability to
create common operational pictures that are
capable of guiding both preparedness and
response.
27To conclude
- If a picture is worth a thousand words, then
certainly an intelligent map is worth much more. - Today's GIS produces intelligent, relevant, and
useful spatial (3D)information that achieves
critical response missions. First responders
deserve nothing less.
