7.4 LINE MEASUREMENT (LINE)
The
Line
Measurement
program
allows
the
user
to
measure
the
height
of
an
inaccessible
object
above
a
point.
Both
the
inaccessible
object
and
the
point
are
located
along
an
established
base
line.
Two
prisms,
A
and
B,
are
set
up
apart
from
each
other
below
the
object
to
establish
the
base
line.
The
horizontal
distance
is
measured
and
set
in
the
instrument
for
both
prism
A
and
B.
The
screen
then
shows
the
vertical
distance
from
prism
A
and
B,
the
horizontal
distance
from
the
instrument
to
prism
B,
and
the
distance
along
the
base
line
and
the
screen
will
display
the
vertical
distance
from
prism
A
to
that
point,
the
horizontal
distance
for
that
point.
Additionally,
the
vertical
distance
between
two
points
on
the
base
line,
Point
G
and
L
in
the
diagram
can
be
measured.
