Transmission of the current inefficient spatial data has become a major bottleneck restricting the development of WebGIS. Multithreaded technology and multi-point connections to improve system throughput, efficient use of system resources and improve the efficiency of communication between the user and so the task has a significant effect. In this paper, the map layer and the segmentation method and the surface Java multi-threading and multi-point connection technology to achieve the efficient transmission of spatial data WebGIS.
