Shows how to use the GetFeature control to select features from a
|
|
WMS layer. Click or drag a box to select features, use the Shift key to
|
|
add features to the selection, use the Ctrl key to toggle a feature's
|
|
selected status. Note that this control also has a hover option, which is
|
|
enabled in this example. This gives you a visual feedback by loading the
|
|
feature underneath the mouse pointer from the WFS, but causes a lot of
|
|
GetFeature requests to be issued.
