摘　　要：中国地理信息产业协会团体标准T/CAGIS 1-2019定义了一种开放式可扩展的空间三维模型数据格式Spatial 3D Model(S3M),适用于空间三维模型数据的传输、交换与共享,有助于解决多源空间三维模型数据在不同终端地理信息平台中的存储、高效可视化、共享与互操作等问题。本文分析了S3M格式的特点和优势,提出基于S3M的多源异构数据跨终端应用框架,并基于S3M SDK利用实际数据进行了功能和性能测试。The standard T/CAGIS 1-2019, which is composed by CAGIS, defines an open and extendable spatial 3D model data format—S3M. It could be used for the transferring,interchanging and sharing of spatial 3D model data, and it is helpful to solve the problems that appear in storage, visualization, interoperation of spatial 3D data among different GIS terminals. The advantages of S3M is proposed in this paper. A cross platform application framework based on S3M is described, and an implementation based on S3M SDK is performed in this paper.
