the viewer, as shown in the following code:
// add layers to map and center it
map.addLayers([osm, wfs]);
var fromProjection = new

a Save Features tool(tosavethefeaturestotheunderlyingWFS-T).Wefirst
create the panel, as shown in the following code:
// create a panel for tools
var panel = new OpenLayers.Control.Panel({
displayClass:
"olControlEditingToolbar"
});
8. Now, we will create the Draw Point tool, as shown in the following code:
// create a draw point tool
var draw = new
OpenLayers.Control.DrawFeature(
wfs, OpenLayers.Handler.Point,
{
handlerOptions: {freehand: false,
multi: false},
displayClass:
"olControlDrawFeaturePoint"
}
);
9. Then, we will create the Save Features tool, using the following code:
