IDW
IDW插值法,距离倒数乘方格网化方法是一个加权平均插值法,可以进行确切的或者圆滑的方式插值。方次参数控制着权系数如何随着离开一个格网结点距离的增加而下降。对于一个较大的方次,较近的数据点被给定一个较高的权重份额,对于一个较小的方次,权重比较均匀地分配给各数据点。 计算一个格网结点时给予一个特定数据点的权值与指定方次的从结点到观测点的该结点被赋予距离倒数成比例。当计算一个格网结点时,配给的权重是一个分数,所有权重的总和等于1.0。当一个观测点与一个格网结点重合时,该观测点被给予一个实际为 1.0 的权重,所有其它观测点被给予一个几乎为 0.0 的权重。换言之,该结点被赋给与观测点一致的值。这就是一个准确插值。 距离倒数法的特征之一是要在格网区域内产生围绕观测点位置的"牛眼"。用距离倒数格网化时可以指定一个圆滑参数。大于零的圆滑参数保证,对于一个特定的结点,没有哪个观测点被赋予全部的权值,即使观测点与该结点重合也是如此。圆滑参数通过修匀已被插值的格网来降低"牛眼"影响。 (Inverse Distance to a Power)
