RWDB2 Features

The following subsections describe the features of the RWDB2 that have been included in STK High Resolution Maps.

Coastlines include the coasts of Africa, Asia, Australia, Europe, Greenland, North America, South America, the Black Sea, and the Caspian Sea.
Ice shelves are found only in Antarctica.

Rank	Description
1	Major islands that should appear on all maps
2	Additional major islands
3	Moderately important islands
4	Additional islands
5	Minor islands
6	Very small minor islands
8	Reefs
9	Shoals

Rank 1 islands should be called out on all maps.
Ranks 5 and 6 are normally found in double-line rivers, in lakes, and between larger islands.

Rank	Description
1	Lakes that should appear on all maps
2	Major lakes
3	Additional major lakes
4	Intermediate lakes
5	Minor lakes
6	Additional minor lakes
7	Swamps
11	Intermittent major lakes
12	Intermittent minor lakes
14	Major salt pans
15	Minor salt pans
23	Glaciers

Glaciers are currently found only in Iceland.
Many small lakes have the same rank as the rivers that run through them; a very small lake may be a rank 2 because a rank 2 river runs through it. Displaying rivers of a certain rank without displaying lakes of the same rank may result in gaps in the rivers (see Rivers, comment 1).
A reservoir may be shown as a double-lined river (see Rivers, comment 3).

Rank	Description
1	Double-line rivers
2	Major rivers
3	Additional major rivers
4	Intermediate rivers
5	Minor rivers
6	Additional minor rivers
10	Major intermittent rivers
11	Additional intermittent rivers
12	Minor intermittent rivers
21	Major canals
22	Minor canals
23	Irrigation canals

When displaying rivers of a given rank, it may be necessary to display lakes of the same rank to prevent gaps in some rivers (see Lakes, comment 3).
Ranks 1 and 2 form the major river systems.
Reservoirs may appear as double-line (Rank 1) rivers (see Lakes, comment 4).

Rank	Description

2	Indefinite or in dispute
3	Lines of separation or sovereignty on land
4	Lines of separation or sovereignty in the sea
5	Other lines of separation or sovereignty in the sea. Represents one generalization when island jurisdiction must be shown
6	Continental shelf boundary in Persian Gulf
7	Demilitarized zone lines in Israel
