| 摘 要： | 地图上等高线的等高距主要有英美制（英尺、码）和公制（米）两种制式，不同制式间的等高线转换，其实质是等高线重构。克里金（Kriging）算法是对空间分布的离散数据进行无偏、线性最优内插估计的一种较理想的插值方法。论述了Kriging算法的基本原理，并以VB＋Surfer为二次开发环境，实现了等高线制式由码至米的转换，分析了该方法应用的主要特点。

| Abstract: | There are two kinds of contour unit in map, inch or yard for England and America, and meter for the world. The quiddity of contour transformation is contour reconstruction. Kriging method is a more ideal method which is a agonic, linear and best estimation for discrete spatial data. This article discusses the theory of Kdging method,realizes the transformation which is from yard to meter with VB＋surfer and analyses the main characteristic of this method. |
