Web-GIS based Decision Support System

TNSMART

Tamil Nadu System for Multi-hazard Potential Impact Assessment,

Alert, Emergency Response Planning & Tracking

CDRRPSupported by

Word Bank

• Disaster database

• Maps of Vulnerable areas

• Weather forecast at various administrative levels (e.g.

state, district, sub-district, village)

• Thresholds to visualize threats

• Hazard Forecast (e.g. Floods, Landslides)

rainfall forecast (e.g. villages and no. of people to be

affected, crop area to be affected)

• Database for Response – database of relief centres, SDRF,

First responders, Hospitals, Escape routes, Equipment

and Machinery etc

Requirements for Disaster Management

• Alarm systems

• Emergency call and message registry

• Tracking Alert/Distress calls

• Tracking risk reduction

• Updation of vulnerable areas based on tracking

performance of mitigation measures

Requirements for Disaster Management

• Continuous updation of database

• Accuracy of the database

• Availability of database on a single easily accessible

platform

• Link between static (e.g. historical disaster risk pattern)

and dynamic (weather/hazard forecast at different lead

times) database.

• Sustainability of disaster database

Issues

TNSMART links Static legacy data with dynamic

hazard/risk (rainfall, cyclone, tsunami) forecast

products to Policy makers, Operational users and

the Community

• disseminate forecast based alerts

• assess potential impacts

• suggests DRR options

• evaluates DRR strategies & measures

• and thereby addresses sustainability of disaster

data base collection and utilization.

A web-GIS based Decision Support System to

strengthen preparedness, response, and

mitigation measures during multi hazards of

Flood, Cyclone & Tsunami, Lightening etc.

Web Application

Mobile Application

• Provides access to observed rainfall data for

all available rainfall stations

• Provides weather forecast and likely flooding

potential for identified vulnerable areas.

• Communication of alerts to field level

functionaries,Media and community

• Citizens could send distress message to the

system which will be forwarded to concerned

officer for actions

• Receive action taken report from field level

functionaries on the alerts forwarded to them

preparedness, response,

recovery and mitigation

TNSMART Aligned with Global Frameworks

TN SMART monitors implementation of strategies to be compliant with

• four priorities set forth in Sendai Framework & Sustainable Development Goals.

• priorities set-forth in Tamil Nadu State Disaster Management Perspective Plan 2018-2030

28

Key Strengths

• Role of TNSMART integrated in Policy documents (State

Disaster Management Plan 2018-2030, Policy Note 2018-19)

• Engagement of operational users from State to Village level

in using the system to ensure data flow.

• Innovative institutional mechanism (RIMES Program Unit

Offsite – RIMES Onsite office – CRA-DM Operations) to

ensure technical support and keeping the system up to

date.

• Transparency in DM by providing access of data to public

and media to mainstream risk communication process

• Building trust with all stakeholders through timely outreach

29

Key Strengths• TNSMART will play a critical role in DRR by

• Saving lives by evacuation to safe shelters

• Saving livelihoods – evacuating animals, safeguarding movable assets, advisory to farmers for minimising the impacts (e.g. pruning coconut trees before the cyclone hit to save crops)

• Prepositioning materials & resources for faster recovery process (infrastructure, power, health) and thereby reduce economic costs

• Will strengthen policy making for DRR by continuous

up dation of database and validation of various DRR measures , guidance for DRR investments and minimise impacts of disaster related losses in tune with SENDAI framework

Transfer of TNSMART Technology

❖ India Meteorological Department has decided to adopt the

application at national level to provide Impact Based Forecasting

Services to all the States

❖ RIMES initiated replication in two more States (Odisha and

U.P) and in 9 other countries based on the demand from its

participating countries

❖ Support by World Bank through CDRRP in TN and keenness

to take it forward in other States and other Countries
