浅谈带状地形图任意分幅的方法

针对带状地形图的特点,介绍了大比例尺带状地形图普通的倾斜分幅方法,提出了任意分幅的方法及其优势。利用AutoCAD二次开发语言,根据图幅结合表提取图幅元数据文件。添加图廓时只需读取元数据文件,程序根据内图廓角点坐标自动计算各注记点位置、角度,自动生成图廓,从而减少了图廓整饰的工作量。

The Method of Random Ampltude on the Ribbon Topographie Map

This text aim at the characteristic of the zonal relief map,introducing the common tilt map subdivision of the large-scale zonal relief map,to put forward the method and superiority of the map subdivision at will.Taking advantage of the Secondary development language of AutoCAD,on the basis of map sheet and graph,to pick up the map sheet element data file.When adding map profile,only need to read element data file,the Program calculate every note point’s position and direction automatically just upon the map profile corner points’ Coordinates,and generate the map profile automatically,thereby reducing the workload of the map profile modifying.
