| 用法 | 返回 |
|---|
FeatureCollection.inverseDistance(range, propertyName, mean, stdDev, gamma, reducer) | 图片 |
| 参数 | 类型 | 详细信息 |
|---|
此：collection | FeatureCollection | 用作估计源数据的特征集合。 |
range | 浮点数 | 插值窗口的大小（以米为单位）。 |
propertyName | 字符串 | 要估计的数值属性的名称。 |
mean | 浮点数 | 全局预期平均值。 |
stdDev | 浮点数 | 全局标准差。 |
gamma | 浮点数，默认值：1 | 确定估计值趋向于全局平均值的速度。 |
reducer | 缩减器，默认值：null | 用于将重叠点的“propertyName”值折叠为单个值的缩减器。 |
