微机测绘地图的一种分割算法

A SPLIT-PLOT DESIGN OF THE PLOTTING MAP BY MICROCOMPUTER

本文采用人—机交互采样,给出了地图绘显和测算的分割算法,从分析地图数据采样和曲线特征,归纳出组成任意地图曲线的凸、凹、折、平、断五种特征点线,以及这些特征点线与面积测算的关系,使地图或其内含子区域的面积测算简单易行。

This paper presents a split-plot algorithm about plotting and displaying map and calculation using man-machine interactive acquire figure. From analysing the data acquisition of the map and the characteristic of curve, the five-characte ristic points and lines of convex, concave, plain, broken and break of arbitrary curve of the map are indut-ed, and the relation between those characteristic points and lines and calculaton of areal are also obtained
