SearchNeighborhoodSmoothCircular

摘要

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
