DLG建库数据到制图数据自动转换程序的研究与实现
|
摘要
提出了一种由DLG建库数据到DWG格式制图数据自动转换的方法,该方法从建库数据与制图数据的特点出发,分11种方式及其组合,来实现建库数据到制图数据的自动转换,这11方式不但能够解决简单符号的转换,而且可以完成如桥梁、植被等复杂符号的转换。同时本文还提出几种解决符号压盖的方法,完善了制图数据的出图效果。本文基于ArcGIS Engine及AutoCAD ActiveX开发了自动转换程序,编写了与11种转换方式相对应的11个转换函数。通过实验证明本文提出的方法能够完成制图数据的自动转换,转换内容全面,不存在丢失的情况,能够自动完成建库数据到制图数据95%以上的转换工作,而且转换结果符合国家标准图示要求,转换效率较高,完成一幅1:10 000标准图幅DLG建库数据到制图数据的转换需要约2～3分钟的时间。
This paper presents a automatic transformation method from DLG warehouse data to mapping data with DWG data format,this method is base on the characteristics of the DLG warehouse data and the mapping data,this method contains eleven ways which achieve the automatic conversion from the DLG warehouse data to the mapping data,and this eleven ways can solve not only the simple conversion of symbols,but also the complex symbol transformation such as bridge,vegetation and so on.At the same time this paper also puts forward several methods to solve the problem of symbols overlap,which can help to improve the effect of mapping data.This paper develop an automatic conversion program based on ArcGIS Engine and AutoCAD ActiveX,it contains eleven conversion functions which come from the eleven conversion ways.It is proved by the experiments that the proposed method can complete the automatic conversion of mapping data,and no information is lost.It can complete more than 95% conversion work from the DLG warehouse data to the mapping data automatically,and the conversion results meet the demand of the national standards,and the conversion efficiency is higher,to complete the conversion from one 1∶ 10000 standard DLG warehouse data to mapping data needs 2~3 minutes.
