[OpenLayers-Users] How do I get my polygon coordinates?

[Nathan Gerber]

I use a different method for getting the polygons as a text string, keep in
mind this is for catching all polygons in the given layer and not for a
selected or recently drawn polygon.

//put in your map init() function
wkt = new OpenLayers.Format.WKT();

//Put this where you desire it to be and modify as necessary
for (var i=0;i<vectors.features.length;i++) {
    //if (selFeatureID == vectors.features[i].id) {}
    var str = wkt.write(vectors.features[i]);
    ajaxSendParams += "&bdySegment="+escape(str);
}
