4. Overview
•
What
are
Geovisualiza<ons?
•
How
do
they
support
explora<on
and
analysis?
•
What
is
the
digital
city?
•
What
kind
of
user
generated
geo-‐spa<al
data
exist?
•
How
can
we
engage
ci<zens?
•
Many

A
map
is
not
the
territory
it
represents,
but
if
correct,
it
has
a
similar
structure
to
the
territory,
which
accounts
for
its
usefulness.

•
Explici<ly

•
Loca<on-‐aware

•
GPS

•
Real
