摘要
利用现有软件功能进行数字化航测DLG新旧图式等数据自动转换,研究新、旧图式DLG数据符号转换技术流程,介绍使用CASS 2008成图软件批量修改数据的图层、编码、图块、线型等方法,使用ObjectArx进行CAD二次开发,实现了各个要素符号线宽的批量转换,提高批量测绘数据处理能力。
The paper introduces the automatic diversion technology of the new and old digitizing aerial survey DLG symbol lists by using the software function in existence and the conversion technological process of the new and old DLG digital symbols, and also presents the some methods of modifying such the data as the layer, encoding, picture segment and linetypes with batch quantity by using the CASS 2008 mapping software. The redevelopment of the software CAD by using the software ObjectArx can carry out the batch transition of the line breadth for each essential symbols, which will enhance the batch processing capability of the surveying and mapping data.
