Notes
1 In some cases PHLNTYPE attribute values of 1 and 3 may be coincident
with railroads or roads. These features are distinguished by textual
annotation.
Point and areal information related to land features are stored in the
Land Cover coverage.
2
Where escarpments, bluffs, and cliffs coincide with contour lines,
large escarpments (ONC 412.2) cannot be distinguished from the smaller
features (ONC 412.1).
3
Ice cliffs are always stored in PHLINE. If they are also part of the
coastline, they are duplicated in political/oceans line feature table.
If they are part of a glacier they may also be stored in drainage line
feature table.
