(a) whether the Ministry has recently conducted a digital
mapping of coastal areas especially in Gujarat for the purpose
of gaining knowledge on resources available, forewarning in
case of tsunamis, cyclones etc.;
(b) if so, the outcome thereof, Statewise; and
(c) the other uses of this digital mapping of coastal
areas in the country?
MINISTER OF STATE IN THE MINISTRY OF PLANNING, MINISTER OF STATE IN THE
MINISTRY OF SCIENCE AND TECHNOLOGY AND MINISTER OF STATE IN THE
MINISTRY OF EARTH SCIENCES(SHRI ASHWANI KUMAR)
(a) Yes Madam.
(b) Indian National Centre for Ocean Information Services
(INCOIS) has initiated work on cutting edge research areas such
as: (i) Multi-hazard Vulnerability Mapping, (ii) Real-time tsunami
inundation modeling as well as (iii) 3-D GIS for street level inundation
estimates within the near coastal most vulnerable zones purely for
the purposes of quantifying depth and extent of coastal inundation
due to tsunami and cyclone generated storm surges.
Tsunami inundation modelling for the areas of Mandvi and Dwaraka in
Gujarat is currently being done by Integrated Coastal and Marine
Area Management (ICMAM) Project Directorate located at Chennai, by
using topographic data obtained through Real-Time Kinematic (RTK)
GPS surveys.
National Remote Sensing Centre (NRSC) is carrying out Airborne
Laser Terrain Mapper (ALTM) survey to generate digital topographic
information for the near coastal zones, for use in inundation modelling.
The data acquisition so far has been completed for Orissa, Andhra Pradesh,
and Tamil Nadu. ALTM-based digital topographic mapping has so far been
completed for near coastal areas between Nagapattinam (Tamilnadu) to
Puri (Orissa). The broad scientific methodologies for 3-D GIS have been
established and pilot work over the Nagapattinam-Cuddalore area of
Tamilnadu has been successfully. Work is under way for the remaining
near coastal most vulnerable zones of the country.
Survey of India (SOI) has completed preparatory work for generating
micro-scale topographic data over Gujarat completed under the Integrated
Coastal Zone Management (ICZM) Program of the Ministry of Environment
& Forests.
Coastal vulnerability mapping for multi-hazards has been completed by
INCOIS at macro-scale for planning purposes for entire Indian coastline
including Gujarat coast.
(c) The Ministry plans to develop micro-scale vulnerability maps
for all the near coastal vulnerable areas of the country that can be
used by administrators and risk managers for micro-level multi-hazard
resilient development planning, ICZM, saving lives and property.
