<p>A style map is used with vector layers to define styles for various
|
|
rendering intents. The style map used here has styles defined for the
|
|
"default" and "select" rendering intents. This map also has an active
|
|
select feature control. When you hover over features, they are selected
|
|
and drawn with the style corresponding the the "select" render intent.
