摘    要:从实地获取的观测数据往往是离散的,为了制作等值线图,通常采用手工方法,它依靠肉眼判断,当离散数据量很大时,这种传统的方法就变得很困难,同时准确性和精度都无法保证。作者设计了一套算法,结合计算机的处理特点,可方便地自动生成等值线,可以满足各种专业的此类需求。作者用C和FORTRAN语言编出了相应的程序,在实际使用中非常高效,并且不受数据量的限制,在普通微机上就能处理。

关 键 词:插值,等值线,矢量,栅格

Abstract:Data from real field work are usually in dispered forms. We often use manual methodrelying on our eyes to make an isograph map. It is very difficult when the data are big quan-tities and then we can't ensure correctness and accuracy. With the help of computes ,the au-thor has designed new methods which can produce accuracy isograh and meet demands inmany fields. The programs in C or Fortran is very efficent in practice without limit in thenumber of data and easily using in a comon micro-commputer.
Keywords:isogragh  vector  grid
