光栏法的基本思想是（图1）：定义一个扇形区域，通过判断曲线上的点在扇形外还是在扇形内，确定保留还是舍去。-The basic idea of ​ ​ light field is (Figure 1): definition of a fan-shaped region, by determining the point on the curve outside the sector or sector, to identify the

矢量数据的压缩方法常用的有道格拉斯—普克法、垂距法、光栏法。本文主要讨论道格拉斯—普克法，运用该算法的思想，用C语言于TC20中编写一个小程序，实现对既有线的简化。(压缩包里面有算法报告)-Vector data compression methods are commonly used Douglas- Puck law, down from the method, light field method. This article f

空间数据压缩，本程序结合了道格拉斯算法、光栏法、垂直距离法对空间数据进行压缩-Spatial data compression, the program combines the Douglas algorithm, light bar, vertical distance of space data compression
