【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。
[Abstract]:At present, there are many problems in format conversion between Auto CAD cartographic data and Arc GIS geographic data, such as information loss, low efficiency, user defined features can not be converted, attribute data can not be automatically converted, and so on. In this paper, the spatial data model structure of two kinds of graphic files is studied, the structure and relation of their spatial graph elements are analyzed, the key technologies involved in the transformation are studied, and the concrete transformation model is put forward. On the basis of theoretical research, the conversion program is written by using .net framework C # object-oriented technology, and the lossless conversion of two kinds of data is implemented, which provides a useful reference for other types of data conversion.
