摘要:城市信息模型（CIM）的建设，需要解决各类数据在统一坐标系下的转换问题。本文梳理了常用坐标系统，分析了不同坐标系统之间的转换原理，介绍了CGCS2000投影坐标系和南京地方投影坐标系下BIM模型转换过程的应用案例，提出了一套在异构坐标体系下集成BIM模型到CIM平台的解决方法。
Abstract: The construction of city information model (CIM) needs to settle transformation of various data in a unified coordinate system. By sorting out the commonly used coordinate systems, this paper analyzes the conversion principles between different coordinate systems, introduces the application cases of the BIM model conversion process under the CGCS2000 projected coordinate system and the Nanjing local projected coordinate system, and finally proposes a set of integration solution from BIM model to CIM platform under heterogeneous coordinate systems.
