Terrain
Data
Terrain
Data
is
colorful
ground
elevation
data
which
shows
mountains,
valleys,
etc.
In
mountainous
areas
it
is
nice
to
be
able
to
compare
the
terrain
seen
out
the
window
with
the
terrain
on
the
map.
However,
the
colorful
data
can
increase
screen
“clutter”
and
make
it
more
difficult
to
see
the
data
you
need
to
see
to
fly
the
task
–
such
as
airports
and
airspace.
Therefore,
some
pilots
will
opt
to
turn
off
the
display
of
terrain
data
(especially
when
flying
in
flat
regions)
to
improve
the
contrast
of
the
display
and
to
reduce
screen
clutter.
•
Culture
Culture
data
includes
cities
and
roads
which
are
displayed
on
the
map
in
shades
of
grey.
As
with
Terrain
data,
some
pilots
will
want
to
view
the
data
to
help
them
confirm
that
the
cities
and
roads
viewed
out
the
window
match
the
data
displayed
on
the
map.
Others
will
prefer
to
turn
off
the
Culture
data
to
reduce
screen
clutter.
It
is
very
easy
to
turn
the
display
of
the
Culture
data
on
an
off.
It
can
be
enabled
and
disabled
independently
of
the
Water
and
Terrain
data.
•
Water
Water
data
includes
rivers
and
lakes
and
other
bodies
of
water.
As
with
the
Culture
and
Terrain
data,
some
pilots
will
want
to
view
the
data
to
help
them
confirm
that
the
rivers
and
lakes
