摘要
建立了由接口文件、接口文件处理器和共享信息模型组成的大地测量数据接口体系结构 ,划分了大地测量数据服务的 3类不同接口类型。在建立了面向对象的接口数据模型的基础上 ,讨论了面向传统用户的控制点数字化成果格式、面向生产过程的大地控制网统一数据结构和面向GIS的大地测量数据交换格式。
The architecture of the geodetic data interface established in this paper is composed of interface file, processor of interface file and sharing information model. And 3 types of data interface of geodetic data services are divided. On the basis of establishing object-oriented interface data model, the digital product format of control points which reflects the data interface view of traditional users, the unified data format of geodetic control networks which reflects data interface view of the process of field work and indoor work and the geodetic data exchange format which reflects standardized data interface view between different spatial information systems are discussed in the paper.
