資源簡介
等值線是一種離散數據的圖形表示方法，在水利、土木、地質、石油勘探等工程和技術領域內廣泛的應用。常規的等值線繪制通常采用網格法，其繪制的步驟一般為：離散數據網
格化；等值點的計算；等值線的追蹤；光滑和標記等值線等。等值線圖的顯示方式一般有兩種：(1)等值線顯示，即采用線條上加注數值標記的方式顯示數據，這種方式的特點是簡捷；(2)采用彩色填充的方法來顯示數據，既用不同的顏色來顯示不同的數據，這種方法的特點是比較直觀。兩種方法的計算機實現也各不相同，一般來說，它們都需要將數據進行要用
到的網格網格化。第一種方法必須進行等值線的追蹤、光滑和標記等值線。而第二種方法可以在追蹤出等值線的基礎上進行，也可以不做等值線的追蹤直接在網格數據上進行操作。
方法實現的難易程度各不相同
