*Aid
name,
LLNR,
and
National ID
number
uniquely AtoN's within districts
only.
Many
AtoN's share the
same
and
numbers
with other districts.
Any
two
among
name,
National ID,
and
LLNR
will uniquely specify an AtoN.
**In a few cases, the assigned state locations of individual
AtoN
may
need
to
be corrected.
The
Coast
Guard
does
not track Aton locations by state.
Whenever
possible, state
assignments
were
made
based
on the
latitude
and
longitude of the
AtoN
using a
Geographic
Information
System
program.
However,
accuracy
was
difficult to attain on
waterways
dividing states,
where
AtoN
are not widely separated. In these cases, we
made
a "best
guess"
and
placed
based
on available information,
such
as location of the
Coast
Guard
unit servicing the aid or position of the next closest
AtoN
with a
known
state assignment. State of
assignment
is a location
descriptor only
and
in no
way
affects a site's priority ranking.
