APPENDIX
30.3.11 Political/oceans coverage.
a. Political/oceans coverage. This coverage contains
political and oceanic naming information. This is the
only coverage encompassing 100 percent of the Earth's
surface. This information is stored in area, line, and
point feature tables. Attribute values are as described
in the value description tables (TABLES 100 and 101).
b. POAREA.AFT attribute definitions. TABLE 102 describes
the political/oceans area feature table (POAREA.AFT)
attribution.
c. POLINE.LFT attribute definitions. TABLE 103 describes
the political/oceans line feature table (POLINE.LFT)
attribution.
d. Legal code combinations. TABLE 104 documents the
correspondence between the DCW coding scheme and the ONC
coding scheme. Since there are two combinatorial
attributes in the political/oceans line coverage, TYPE
and STATUS, a combination of the two must be used in
order to correspond to the ONC scheme. NC means that
there is no code for the ONC. For example, the boundary
that is considered dejure by one country and defacto by
another has no ONC code; it is only mentioned in the ONC
Specifications. Some ONC codes, for example, must be
combined to accommodate the terms "Approximate" or
"Indefinite" with any of the boundary symbols. In this
specific instance, the DCW coding scheme provides
greater differentiation than the ONC scheme.
e. POPOINT.PFT attribute definitions. TABLE 105 describes
the political/oceans point feature table (POPOINT.PFT)
attribution. This coverage contains those island
features that did not meet the minimum polygon
resolution and were captured as points.
f. Text feature table. TABLE 106 provides an example of
the schema for the political/oceans text feature table
(POTEXT.TFT). Text stored in text primitive tables
includes: land place names, ocean place names, ice
status, mountains, islands, and deserts.
