NATIONAL DISASTER DATABASE - NEED AND CHALLENGES
Principles of Emergency management
1. Comprehensive
2. Risk-driven
4. Collaborative
5. Coordinated
6. Creative and innovative
7. Science and knowledge-based approach for continuous
improvement.
Disaster Database has to address all the above principles
Planning & Policy decision
1. Legacy Data for trend & pattern
analysis.
2. Hazard mapping & Vulnerability
Assessment.
3. Database of disaster management plan.
4. Awareness & training materials.
5. Inventory of legal, techno legal,
administrative & institutional
framework.
6. Database of Financial sources.
Disaster Database for Emergency Management
Quick emergency Response &
Recovery
1. Human & Material response
resources database.
2. Database of Infrastructure,
lifelines & critical facilities.
3. Database of trained human
resources.
4. Demographic information.
5. GIS based information
system and simulation
modelling.
Disaster Database is relevant in order to address all the 4
priorities under Sendai Frame work for Disaster Risk Reduction;
Priority 1: Understanding disaster risk.
Priority 2: Strengthening disaster risk governance
Priority 3: Investing in disaster risk reduction for resilience.
Priority 4: Enhancing disaster preparedness for effective response, and to «Build Back Better» in recovery, rehabilitation and reconstruction.
Disaster Database - NDEM
• National Database for Emergency Management (NDEM)
is conceived as a GIS based repository of data to support
disaster / emergency management in the country.
• NDEM is planned as a multi-institutional coordinated
effort & encompasses all emergency situations arising out
of disasters.
• It assists the disaster managers at various levels in
decision making for managing emergency situations.
Accomplishments
Existing Disaster Database - NDEM
• Dashboard
• NDEM provides disaster related live & historical
news/alerts/warnings obtained from the available sources.
• Daily rainfall, temperature, water level etc., are
integrated into dashboard as a service.
• It is proposed to link Data forecasting agencies such as
IMD, CWC, INCOIS etc., with NDEM portal for directly
obtaining the daily updates through dashboard.

• IDRN is a nation-wide electronic inventory of
resources that enlists equipment and human
resources, collated from districts, states and
national level agencies.
• At present IDRN has about 1.5 lakhs records
from all the states / UT’s of the country.
India Disaster Resource Network (IDRN)
TNSDMA
• Vulnerability analysis at Firka level (sub-taluk) in
Rural areas and Ward level in Urban areas.
• Primary data is converted into Maps.
Existing Spatial Data available in Tamil Nadu
• Administrative boundaries
• Health and Hospitals
• Transport network
• Schools
• Water resources
• Watersheds
• Tele communications
• Dams and Reservoirs
• Forests
• Public infrastructures
• Sports & Stadium
• Industrial locations
• TNEB
• Police stations
• Database of Bridges and
Culverts.However, integration of GIS Layers for
emergency management is under process.
• Integration of legacy data of vulnerability with forecast
information from IMD, INCOIS, CWC, etc.,
• Mobile based applications for gathering Big data
both from Government sources (multiple agencies) &
Crowd sourcing of disaster related data
through Social Media platforms.
Challenges
•Areas in harm's way to be identified real time, to
provide warnings and notifications to the
stakeholders
of pending, existing, or unfolding emergencies
based on the location or areas to be impacted
by the incident – Push SMS.
• Validation and regular updation of data.
Challenges
Development of simulation models by
linking legacy data, rainfall data(Big data) &
forecast data
using Predictive Analytics & other Data
Analytics to
assess the inundation levels and
vulnerability of different locations (including
data from crowd sourcing)
during Storm Surge/or any disaster.

Categorisation of Inundated areas
An attempt was made to categorise the inundated areas
based on dates on which the areas were inundated.
duration of inundation.
• Capturing geo-tagged images of Vulnerable areas
based on
• historical data,
• during and post disaster phases,
• so that field data & high resolution satellite images
can be integrated for emergency management.
Recommendations
In every State
• Areas of Very high Vulnerability & High Vulnerability
should be mapped for different disasters
using Aerial photogrammetry(UAV based),
Light Detection and Ranging (LiDAR) &
High Resolution Satellite Imagery
for use on a GIS Platform.
• GIS applications should be developed for efficient
emergency management.
Recommendations
Need to develop 3D/2D simulation models forStorm Surge, Flood inundation, Seismicity to
a) Predict areas in the harm’s way
b) Intensity of the hazard
c) Assess assistance required for rescue &
evacuation
d) Initiate arrangements for relief operations
e) Assist in Prevention, Preparation and Mitigation
measures
Recommendations
• To meet the emergency management needs,
professional tools and technology such as Data
Analytics (Descriptive analytics, Predictive analytics
and Prescriptive analytics) are required.
• However, the technology has to be robust to withstand
attacks of Virus (WannaCry Ransomware episode)
Conclusion
Technology is very important
but
.Institutional and
Organisational
strength
are more
important
THANK YOU
• Big Data analytics have moved from being descriptive (based on past information using statistics – Business Intelligence to understand what happened) to inquisitive analytics (why it happened) to being predictive (used past information to predict future outcomes- Data mining and forecasting for what is likely to happen) to being prescriptive (used past information to direct future results –optimization to arrive what should happen).
• Big data analytics is the process of examining large and varied data sets --i.e., big data -- to uncover hidden patterns, unknown correlations,, and other useful information that can help organizations make more-informed decisions.
• Large volumes of data sets — commonly referred to as big data — derived from sophisticated sensors and social media feeds are increasingly being used by government agencies to improve citizen services through GIS mapping.
• Predictive analytics is the branch of the advanced analytics which is used to make predictions about unknown future events.
• Predictive analytics uses many techniques from data mining, statistics, modeling, machine learning, and artificial intelligence to analyze current data to make predictions about future.
Big Data is the name given to our ever-increasing ability to collect more data from a multitude of sources, and analyze it for insights using advanced computer algorithms.
In data analytics are classified into three levels according to the depth of analysis:
• Descriptive Analytics : exploits historical data to describe what occurred.
• Predictive analytics: focuses on predicting future Probabilities and trends.
• Prescriptive analytics: addresses decision making and efficiency.
For example, simulation is used to analyze complex systems to
gain insight into system behavior and identify issues and
optimization techniques are used to find optimal solutions
under given constraints.
