In order to meet the need for 3D real-time dynamic visualization of mass terrain data, the spatial database in Grid GIS is taken as the data source of large-scale terrain scenes. Mass terrain data from distributed heterogeneous GIS spatial database are integrated, and their storage and access methods are designed on the basis of grid concept, ensuring that 3D terrain scene from any spatial information source can serve users on demand anywhere at any time. In addition, according to the requirements for low delay and high throughput of terrain data transmission, both the filtering mechanism of terrain data and multi-path data transport service are proposed so as to achieve the best possible viewing experience under the current network conditions. The experimental results show that the proposed mechanism is effective.
