In order to avoid the lack of traditional grid model,the paper makes use of a grid service model based on SOA,which is made up of LAN-grid,WAN-grid and application layer of grid.Spatial data managing grid can integrate all distributed data into a super-large,virtual spatial DB.It can realize mass spatial data management of the whole country or global,and eliminate isolated island of information.Lastly,a Web Viewer(Web 3DTerrain Viewer) of mass 3D terrain is developed based on spatial data managing grid.
