Example

//设置要计算面积的几何对象点集
 var dots = [new Zondy.Object.Point2D(15, 23), new Zondy.Object.Point2D(54, 96), new Zondy.Object.Point2D(65, 42), new Zondy.Object.Point2D(15, 23)];
 //初始化面积测量服务
 var calArea = new Zondy.Service.CalArea(dots, {
                    //IP地址
                    ip: "develop.smaryun.com",
                    //端口号
                    port: "6163"
                });
 //建议普通用户采用此类直接获取MapGIS GDB 已经提供的空间参考系
 var gdbInfo = new Zondy.Object.CGDBInfo({
                    //数据库名称
                    GDBName: "OpenLayerVecterMap",
                    //数据源名称
                    ServerName: "MapGISLocal",
                    //除MapGISLocal数据源，其它的都设置
                    Password: "",
                    //除MapGISLocal数据源，其它的都设置
                    User: ""
                });
 //用于进行SRSID投影的参数类
 var projBySRSID = new Zondy.Service.CProjectBySRSID(601, gdbInfo);
 calArea.execute(projBySRSID, function (res) {
                    console.log(res);
                }, function (error) {
                    console.log(error);
                });
