摘　　要：在最近几年的广州市管线放线测量工作中,不少单位采用报建图,是南方测绘的CASS基础地形数据的管线设计图,因此必须向广州市管线信息系统(GUPIS)数据转换。通过分析它们的结构特点与导入到管线信息数据库的数据要求,提出相应的转换方法,编制了图形数据转换的LISP程序,完成了对复杂地物和管线的图层、线型、颜色的自动分类和转换处理,介绍CASS转换菜单的生成,列举应用于广州某公司的从化区的报建放线测量项目转换的成功案例,提高了生产效率,可为同类项目提供参考。In the work of pipeline coordinate layout survey in Guangzhou in recent years,a few units have adopted the drawing submitted to the government for construction,which is the pipeline design drawing of SOUTH CASS foundation topography data,so it must be converted to the data of Guangzhou Pipeline Information System(GUPIS).By analyzing their structural characteristics and the data requirements imported into the pipeline information database,the corresponding conversion method is put forward,and the LISP program of graphic data conversion is compiled.The automatic classification and conversion processing of layers,line types and colors of complex ground objects and pipelines are completed,and the generation of CASS conversion menu is introduced.This paper lists the successful case of the conversion of the application for the layout survey project submitted to the government for construction of a company in Conghua District in Guangzhou,which improves the production efficiency and can provide reference for similar projects.
