摘要
目前Auto CAD制图数据与Arc GIS地理数据在格式转换上普遍存在着信息丢失、效率低下、用户自定义的地物无法转换、属性数据不能自动转换等问题,对两种图形文件的空间数据模型结构进行了研究,分析它们空间图元结构与关系,研究转换中涉及的关键技术并提出具体转换模型。在理论研究的基础上采用.net框架C#面向对象技术编写转换程序,实行了两种数据的无损转换,为其他类型的数据转换提供了有益参考。
Currently the format conversion between AutoCAD drawing data and ArcGIS geographic data has a widespread loss of information, inefficient, feature of user-defined can＇t be converted, attribute data can＇t be automatically convert- ed and so on, so we studied the spatial data model structure of two kinds of graphics files, analyzed spatial entity structure and relationship, researched key technology involved conversion and proposed specific conversion model. Based on C # . net framework, this paper implemented losses conversion of two kinds of data, and it also provided the beneficial reference for other types of data conversion.
