| Abstract: | 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. |
