And
so
I've
got
these
flags
now
at
a
hundred
feet
perfectly
in
line
and
how
do
I
know
it's
in
line
the
middle
of
that
PVC
pipe
in
my
crosshairs
and
the
level
is
level
three
legs
to
be
level
right
here.
Right,
yes,
and
you
can
see
them
before
you
take
the
shot
every
time
you
move
it,
you
gotta
be
sure
that
that
is
in
that
circle.
A
I'm
in
line
set
this
transit
up
level
and
then
I'm
gonna
turn
90
degrees,
turn
back
to
zero
and
shoot
the
hundred
feet.
That's
a
farthest
flag,
the
other
way
at
the
farthest
flag
and
so
I'm,
going
to
end
up
with
100
foot,
squares
and
I
can
actually
take
a
peat
can,
and
if
it
comes
to
that
here,
I
did
because
I'm
I
was
bare
I
mowed
the
field
and
then
I
laid
everything
out.
A
So
now
it's
easy
to
take
a
piece
of
paper
with
a
hundred
foot
square
grids
on
it
and
I
can
walk
out
there
and
measure
triangulate
every
curve.
Every
everything
right
tell
my
contours
then
get
transferred
to
my
map.
Okay,
so
you'd
start
with
the
the
visual
transit
first
and
then
you
do
the
contours
of
elevation.
I
would
yes,
I
would
grit
it
and
then
I
would
shoot
contours.
And
typically,
when
you
set
up
here,
you're
gonna
move
this
back
a
little
bit.
A
Well,
I
set
it
up,
so
that
I
would
want
to
go
as
close
to
this
line
as
I
could,
because
this
is
an
obvious
boundary
right
and
you
would
set
up
if
you're
gonna
do
this
set
up
over
there
down
there
shoot
out
here
and
then
walk
this
line
of
hundred
feet.
Shooting
this
way.
What's
the
strategy,
if
you're
and
thick
you
know
rough
terrain,.
A
Yeah
so
I
just
get
on
the
tractor
takes
two
of
us
right.
You
know
I
tell
eyesight
and
he
stands
there
with
that
thing
and
then
I'm
driving
the
tractor
to
him
and
I've
got
a
lot
of
site
and
I
can
paint
that
because
I'm
gonna
be
taping
and
measuring.
When
I've
got
my
skill.
Drawing
of
here's
the
tree
and
I
know
it's
gonna
start
at
ten
feet.
Diameter
and
it's
gonna
end
up
at
forty
feet.
Diameter
that's
scale.
Drawing
is
right.
A
To
scale
and
ground
truthing
is
this
process?
Yes,
transit
out
yeah,
and
this
one
of
these
visual
transits
would
I
get
them.
This
is
a
home
depot.
Nothing
I've
got
here
is
how
much
that
was
two
hundred
and
forty
dollars.
That's
a
pretty
expensive
piece
of
equipment.
You
can
get
a
cheap
one.
I!
Never
would
tell
you
to
buy
that
white
or
burger.
$120
deals
it's
if
you
turn
them.
They
are
immediately
off
they're
unreliable
for
amateurs.
