梯形分幅经纬图框自动绘制的研究

STUDY ON THE AUTOMATICAL DRAWING OFLONGITUDE-LATITUDE FRAME ON TRAPEZE

本文介绍了采用梯形分幅图幅号、自动求解经纬图框参数的方法，论述了采用Ｔｕｒｂｏｃ和ＡｕｔｏＣＡＤ绘图软件开发绘制经纬图框模块的技术和方法。开发的模块，只需输入标准图幅号，就能自动生成在ＡｕｔｏＣＡＤ状态下绘制经纬图框的绘图数据文件（·．ＳＣＲ），同时，还具有自动排错功能。

This paper presents a method which calculates automatically parameters for longitude-latitude frame accgrding to the trapeze sheet number. On the basis of Turboc and AutoCAD drawingsoftware, the module of drawing longitude-latitude frame is developed. Inputtins only normal sheetnumber, the module, which is developed,can automatically generate drawing data file (*.SCR) ofdrawing longitude-latitude frame under AutoCAD. The module has also ability of detecting error ofthe sheet number.
