Virtual globe-based integration and sharing service method of GeoSpatial Information

How to integrate and disseminate globally distributed multi-source and heterogeneous spatial information is an open problem in integration and sharing service of geographic information. Here we propose a new service architecture suitable for integration and sharing of distributed multi-source geographic information. We also propose a global virtual pyramid model, which can be applied in 3D virtual globes. In view of the difficulty of web multi-node geographic information sharing service, we propose a web multi-node service aggregation method, integrated in our autonomously developed virtual globe platform Geo-Globe and introduced in the National Platform for Common GeoSpatial Information Services named “TIANDITU”. It achieves 2D and 3D integration for geographic information service.
