Lack

“Isolated” data set

Recent trends:
•  Wiki approach in data production
•  Volunteered geographic information
•  Crowdsourcing
•  Neogeography (geotg, blogs, etc.)
•  …


Infrastructure

Lack
of
data
vs
interoperability

Three main barriers:

•  Bureaucratic: poor practice in sharing data
•  Technological: differences between systems
and data formats
•  Semantic: lack of correspondance in
meanings.

Conclusions

•  Interoperability
-‐>
produced
“uniﬁed
legends”
??

•  SDI
-‐>
semanRc
approach
could
reinforce
the

usability
of
the
systems

•  SemanRc
correspondence
brings
to
interoperability

not
only
between
data
sets
but
also
in
the
process
of

management
plans
and
intervenRon
programs.
