摘　　要：分析了均匀网格化数据等值线处理的具体步骤 ,介绍了非均匀网格分布数据的均匀网格化处理中的 3种方法 :按距离加权的最小二乘法 (N— P法 )、按方位取点加权法和加权最小二乘法拟合法 (M— S法 ) ,提供了 N— P法和 M— S法的The specific of isoline process of homogeneous gridding data are briefly analyzed This paper detaliedly introduces three methods used for processing heterogeneous gridding data,that is,weighing least square method by distance (namely N-P method),weighing pointing method by azimuth weigh method and fitting method by weighing least square method (namely M-S method) Microsoft Visual C ++ source programs for N-P method and M-S method are provided in this paper
