Answer 1

It would be better to draw the circle with OpenLayers. But if you want to do it with the GMaps API, you can use the following to get a reference to the GMaps map instance:

var googleLayer = new OpenLayers.Layer.Google(/* ... */);
var gmap = googleLayer.mapObject;

Thanks. draw a circle with openlayers.(http://openlayers.org/dev/examples/regular-polygons.html)

I'm trying to intersect a user drawn polygon(circle) with a Point WMS Feature Layer. I am using the following code

   result = [] testPolygon = vectorTest.features[0].geometry;for (var i=1; i<vectorTest.features.length; i+=1) {
if testPolygon.intersects(vectorTest.features[i].geometry) {
    result.push(vectorTest.features[i]);
} }

but it's not working
