T/CAGIS 2-2020 Spatial 3D Model Data Service Interface

Scope

Scope: This standard specifies the basic requirements, overall framework, and interface definition for spatial 3D model data services. This standard applies to the web publication and access of spatial 3D model data. Main technical content: T/CAGIS 1—2019, *Spatial 3D Model Data Format*, standardizes the data format of multi-source heterogeneous spatial 3D models (S3Ms), providing a standard basis for the open sharing of 3D spatial data. At the data application level, there are not only local access modes but also a large number of lightweight online access modes. Establishing a service interface standard that complements the S3M data format standard is conducive to interconnectivity, mutual access, and interoperability among different application systems, and is of great significance for promoting the further popularization and use of the S3M data format standard. This standard specifies the spatial 3D model data service interface corresponding to T/CAGIS 1—2019, which is a web access interface for cloud services, edge services, desktop clients, and mobile devices, providing support for the publication and sharing of spatial 3D model data.
