2. Disaster Management
Topic :-
GEO-INFORMATION IN DISASTER
MANAGEMENT
(RS,GIS,GPS and RS)

3. GEO- INFORMATION
 A Geographic Information System
(GIS) is a computer-based system
including software, hardware, people,
and geographic information
 A method to
visualize, manipulate, analyze, and
display spatial data
to study the world

5. GIS OBJECTIVES
 MAXIMIZE THE EFFICENCY OF
PLANNING AND DECISION MAKING.
 PROVIDE EFFICENT MEANS FOR DATA
DISTRIBUTION AND HANDLING.
 ELIMINATION OF REDUNDANT
DATABASE-MINIMIZE DUPLICATION.
 CAPACITY TO INTEGRATE
INFORMATION FROM MANY
SOURCES.
 COMPLEX ANALYSIS/ QUERY
INVOLVING GEOGRAPHICAL
REFERENCED DATA TO INTEGRATE

6. How GIS use in disaster
management
1) EARTQUAKE
 GIS can be useful for monitoring
historical sites of earthquake also to
Response & data management for
recovery.
 It’s also useful for Impact assessment.

7. 2) FLOOD
•Flood mapping from Macro level to Micro
level.
•Flood Zone mapping.
•Detecting Potential Site of Flood in reference
with rainfall
•Elevation Mapping
•Preparing Response map in response to
manage after flood situation

8. Situational Awareness
 Disaster and emergency management in
situational awareness is essential thing.
 GIS techniques plays vital role to provide
locational information of the event, that is,
where is the event happened and what
happening exactly in real time.
 Also by linking people, processes spatial
information situational awareness
established.
 GIS map interface important in handling
emergency condition.

9. REMOTE SENSING
 Quickly assessing severity and impact
of damage due to flooding,
earthquakes, oil spills and other
disasters
 Rapidly identifying hardest-hit disaster
areas in order to provide early warning
of potential disasters
 Developing, maintaining or updating
accurate base maps

11. •the science of acquiring information
about the Earth using remote
instruments, such as satellites is
inherently useful for disaster
management.
•Satellites offer accurate, frequent and
almost instantaneous data over large
areas anywhere in the world.
• When a disaster strikes, remote
sensing is often the only way to view
what is happening on the ground

12. REMOTE SENSING FLOODING
 Using remote technology however,
would allow response workers to stay
away from danger zones while at the
same time gather pertinent information
to facilitate timely response, rescue
and relief efforts.
 It is always going to be difficult, if not
impossible, for planners to identify all
the areas likely to experience flooding
in any location

14. Remote sensing and
Earthquakes
 This technology will help in identifying
the structural and non-structural
earthquake hazards that are present
and employ the most appropriate tool
for minimizing these risks.
 Using remote sensing technology,
however, would significantly improve
the timeliness and quality of aid that
can be provided.
 it would be advantageous to employ
the service of remote sensing for deep

17. GPS (global positioning
system)
 The Global Positioning System (GPS) is a
satellite-based navigation system made up
of a network of 24 satellites placed into orbit
by the U.S. department of Defense.
 GPS was originally intended for military
applications, but in the 1980s, the
government made the system available
for civilian use.
 GPS works in any weather conditions,
anywhere in the world, 24 hours a day.

19. How GPS Works: Overview
Receivers use an almanac that includes
The position of all satellites every second
This is updated monthly from control stations
The satellite signal is received, compared
with the receiver’s internal clock, and used to
calculate the distance from that satellite
Trilateration (similar to triangulation) is used
to determine location from multiple satellite
signals
