Subfields
$d, $e,
$f, and $g
individually identify the four coordinates of the item. Subfield
$d represents the westernmost
extent of the item; subfield $e,
the easternmost extent; subfield $f,
the northernmost extent; and subfield $g,
the southernmost extent. The abbreviations for the hemispheres are:
N
= North, S = South, E
= East, W = West.
These four subfields always appear together.
The coordinates may be recorded in the form hdddmmss
(hemisphere-degrees-minutes-seconds), however, other forms are also allowed,
such as decimal degrees. The subelements are each right justified
and the unused positions contain zeros.
Examples
in degrees/minutes/seconds: hdddmmss
(hemisphere-degrees-minutes-seconds):
034 1# $aa$b22000000$dW1800000$eE1800000$fN0840000$gS0700000
034 1# $aa$b253440$dE0790000$eE0860000$fN0200000$gN0120000
[The above two examples illustrate records for flat maps or flat maps in atlases.]
Example
in decimal
degrees: hddd.dddddd (hemisphere-degrees.decimal degrees):
034 1# $aa$dE079.533265$eE086.216635$fS012.583377$gS020.419532
Example
in decimal
degrees: +-ddd.dddddd (hemisphere[+/-]-degrees.decimal degrees)
("+" for N and E, "-" for S and W; the plus sign is
optional):
034 1# $aa$d+079.533265$e+086.216635$f-012.583377$g-020.419532
Example
without the optional plus sign:
034 1# $aa$d079.533265 $e086.216635$f-012.583377$g-020.419532
Example
in decimal
minutes: hdddmm.mmmm (hemisphere-degrees-minutes.decimal
minutes):
034 1# $aa$dE07932.5332$eE08607.4478$fS01235.5421$gS02028.9704
Example
in decimal seconds: hdddmmss.sss
(hemisphere-degrees-minutes-seconds.decimal seconds):
034 1# $aa$dE0793235.575$eE0860727.350$fS0123536.895$gS0202858.125
If
the coordinates are given in terms of a center point rather than outside
limits, the longitude and latitude which form the central axis are recorded
twice (in subfields $d and $e and in $f
and $g, respectively.)
Examples:
034 1# $aa$b75000$dW0950500$eW0950500$fN0303000$gN0303000
