Latitude
and

1.
Watch
the
two
videos
on
Folio
about
latitude
and
longitude
(Movie
1
and
Movie
2).
When
you
watch
videos
on

it
will
log
that
you
watched
them.
If
you
don’t
watch
the
videos,
your

will
be
considered
incomplete.

Watch
Movie
3
on
Folio.
This
is
a
superb
video
that
explains
how
to
find
locations
on
a
top
using
UTM
coordinates
and
a
UTM
grid
overlay.
Initial
here
that
you
watched
the
movie
21.
Download
and
open
the
map
on
Folio
titled
Lafayette
Cropped
Points
Grid.
Overlain
on
the
map
isa
UTM
grid
overlay,
the
same
as
the
one
you
will
use
in
lab.
The
UTM
grid
overlay
allows
you
to
pinpoint
the
UTM
coordinates
of
any
location
to
within
25
meters.
Notice
that
in
each
100m?2
box
is
a
small
black
dot.
This
dot
represents
the
midpoint
of
each
box
(50
m
from
each
side
of
a
small
box).
