= 0.1，该情况调用等值面服务的时候，就会直接报错400

Answer 1

等值面加载方法如下：

//表面分析参数设置类。

    let setOptions = {

        //裁剪面对象，如果不需要对操作结果进行裁剪，可以使用 null 值取代该参数

        clipRegion: clipRegion,

        //提取等值线、提取等值面的基准值

        datumValue: 0,

        //expectedZValues

        //等值距。等值距是两条等值线之间的间隔值

        interval: 2,

        //重采样容限

        resampleTolerance: 0,

        //光滑处理所使用的方法:BSPLINE:B 样条法,POLISH: 磨角法

        smoothMethod: L.supermap.SmoothMethod.BSPLINE,

        //等值线或等值面的边界线的光滑度

        smoothness: 3

    };

    let analystParametersSetting = new L.supermap.SurfaceAnalystParametersSetting(setOptions);

    //输入数组转墨卡托坐标系

    let points: Array<any> = [];

    let zValues: Array<number> = [];

    for (let item of pointArr) {

        points.push(_getMercator({ lat: item[1], lng: item[0] }));

        zValues.push(item[2]);

    }

    //console.log("points", points);

    //console.log("points", points);

    //console.log("points", JSON.stringify(zValues));

    //几何对象表面分析参数类。

    let parameterOptions = {

        //表面分析的坐标点数组

        points: points,

        //表面分析的坐标点的 Z 值数组

        zValues: zValues,

        //获取或设置指定中间结果（栅格数据集）的分辨率

        resolution: 3000,

        //结果返回设置类

        //resultSetting

        //获取或设置表面分析参数

        extractParameter: analystParametersSetting,

        //取或设置表面分析的提取方法:ISOLINE 等值线提取, ISOREGION 等值面提取

        surfaceAnalystMethod: L.supermap.SurfaceAnalystMethod.ISOREGION

    };

    let surfaceAnalystParameters = new L.supermap.GeometrySurfaceAnalystParameters(parameterOptions);
