• To

potential to the optimum, SWaRMA has come
out with a strong e-Governance tool, with inter-
Sectorial common data base which will be a GIS
based web enabled one.

as well as details of Water Users Association

also been incorporated in this web enabled GIS

This

is
a
comprehensive solution for accessing water
data, capable of geo-visualization and will
help the administrators with e-Governance
tool in the management and Basin planning
of water resources and in taking Tamil Nadu
forward
to
optimise
the
utilisation
of
created irrigation potential and to maximise
crop production per unit of water.
• Taking into consideration the sustainability
and scope for improvising the data Base from
time to time to match to the state of art of the
subject this GIS based web enabled data base
has been created using the available open
source soft-wares, in-house by TN SWaRMA,.
• Government bodies can have factual data on
water from this Web GIS interface, that can be
used for decision making.
• Maps and other non-spatial data related to
many themes and parameters, collated from
many
departments
and
presented
on
a
centralised and common platform for use by
all
concerned.
This
efficient
sharing
mechanism will keep everyone abreast with
latest information. Data query, charting, and
visualization will enhance the analytical depth,
for providing rational and timely service to the
public at large.
