主要是对WFC加载的图层一些后续的操作（增加特征，与原来1.2的版本有所不同）。

画点：

var pointLayer:VectorLayer = VectorLayer(map.getLayerByIdentifier("pointend_track")) ;
                var pointmarker:PointFeature = PointFeature.createPointFeature(new Location(123.85680,50.75336));
                pointLayer.addFeature( pointmarker);

画线：

//获取WFC加载的地图层
                var roadLayer:VectorLayer = VectorLayer(map.getLayerByIdentifier("road")) ;
                //组装坐标数据
                var array:Vector.<Number> = new Vector.<Number>();  
                array.push(Number(104.094413757324),Number(30.7053699493408));  
                array.push(Number(104.081871032715),Number(30.6603736877441));  
                array.push(Number(104.110618591309),Number(30.640344619751)); 
                array.push(Number(95),Number(33)); 
                //创建线的对象
                var lineMark:LineStringFeature = new  LineStringFeature(new LineString(array));
                //地图层增加线的特征
                roadLayer.addFeature(lineMark);

画多边形：

//获取WFC加载的地图层
                var roadLayer:VectorLayer = VectorLayer(map.getLayerByIdentifier("road")) ;
                //组装坐标数据
                var pablepoints:Vector.<Number> = new Vector.<Number>(); 
                pablepoints.push( Number(89),Number(38));
                pablepoints.push( Number(91),Number(38));
                pablepoints.push( Number(91),Number(35));
                pablepoints.push( Number(87),Number(34));
                pablepoints.push( Number(89),Number(38));
                var pableLinearRing:Vector.<Geometry> = new Vector.<Geometry>();  
                pableLinearRing.push(new LinearRing(pablepoints));  
                //样式设置
                var style:Style=new Style();  
                style.rules[0]=new Rule();  
                style.rules[0].symbolizers.push(new PolygonSymbolizer(new SolidFill(0x99D0F2,0.5), null));  
                //创建多边形的对象
                var mappable:PolygonFeature = new PolygonFeature(new Polygon(pableLinearRing),null,style);  
                //地图层增加线的特征
                roadLayer.addFeature(mappable);
