描述
SearchNeighborhoodSmoothCircular 类可用于定义以下邻域搜索方法：经验贝叶斯克里金法、反距离权重法、局部多项式插值法、和径向基函数插值法（仅在使用 INVERSE_MULTIQUADRIC_FUNCTION 关键字的情况下使用）。该类接受输入的搜索圆半径和平滑系数。
语法
SearchNeighborhoodSmoothCircular ({radius}, {smoothFactor})| 参数 | 说明 | 数据类型 |
radius | 以地图单位指定搜索圆的半径长度的距离。 | Double |
smoothFactor | 确定要执行的平滑量：0 为无平滑；1 为最大平滑量。 | Double |
属性
