Description:

Provides a compact way to represent points for features.

Restrictions:

None

Notes:

The separators between the x,y coordinates and the coordinate pairs can be changed. The default separator between two coordinates is a space, and the default separator between coordinate pairs is a semicolon (;). For more information see SEPARATORS.
COORDS uses a compact method for listing the x,y coordinate pairs of a feature in the format of
    <RING>
        <COORDS> x1 x2;y1 y2;...xn yn </COORDS>
    </RING>

The equivalent noncompact method of listing x,y coordinate pairs is to use the POINT element as follows:
    <RING>
      <POINT x="x1" y="y1" />
      <POINT x="x2" y="y2" />
      <POINT x="xn" y="yn" />
    </RING>
Using COORDS means the geometry requires less bandwidth by the request or response. However, performance may be better when the non-compact format is used even though the requests and responses are longer. This is especially true when geometry is written to an acetate layer.
For the different options of representing geometry in an acetate layer, see OBJECT.

Examples for COORDS:

Example 1: Used to define a spatial filter in CONFIG or REQUEST.
