  1. 1. HYDROSYS PROJECT
OVERVIEW
&
APPLICATIONS EPFL‐EFLUM
Dec.
10th
2009
  2. 2. Project
Goals
  3. 3. Project
Goals  Enabling
on‐site
data
collec0on,
visualiza0on
and
transfer
to
support
new
 ways
of
observing
environmental
processes.  Providing
a
system
infrastructure
to
support
teams
of
users
in
the
on‐site
 monitoring
of
events
and
analysis
of
natural
resources.
It
introduces
the
 innova0ve
concept
of
event‐driven
campaigns
using
handheld
devices,
 poten0ally
supported
by
an
unmanned
aerial
vehicle
(UAV).  Improving
monitoring
and
management
for
environmental
scien0sts,
 ins0tu0ons,
service
providers,
engineering
companies
and
municipali0es
 through
its
strong
integra0on
of
handhelds,
sensor
networks
and
modeling. 
