本文介绍了切面截距加权平均网格化算法的方法原理.这种算法能较好地反映随机点的数据的趋势特征,适用广,计算速度也较快.文中通过实例将它与按距离平方倒数加权平均法和局域加权最小二乘拟合法作了比较。
This paper introduces the principle of section intercept weighted average gridding algorithm, which can well reflect the trend characteristics of random point data, has wide applicability and fast calculation speed.This paper compares it with the square of distance squared The reciprocal weighted average method and the local weighted least squares fitting method are compared.
