基于面向对象原理的数字地图符号设计方法研究

Studying on the Method of Drawing Digital MapSymbol Based on Object-oriented Programming Principle

基于面向对象编程原理,对数字地图的符号按面向对象的分类方法进行分类,详细说明了各类数字地图符号在计算机上的绘制方法,并在对线状符号的处理上改进了以往的传统做法,提出了新的思路,使程序实现更为方便,提高了程序执行效率。

Classify digital map symbol according to object-oriented classing method,based on object-oriented programming principle, detailedly explain the method of drawing digital map symbol in computer, and improve the old way about deal with line-figure map symbol, put forward new means which making programming convenient and improving executing efficiency.
