Abstract

With the rapid increase in the amount of spatial data and the number of geospace information system users, current network architecture of geospace information system mainly based on a single server has two primary data transport bottlenecks: the bottleneck of network services throughout provided by the server and the bottleneck of I/O throughout of the storage system for distributed spatial data. In order to avoid both bottlenecks, we present a C/S mode geospace information system based on double-cluster, namely server cluster and storage cluster, and it is called GlobeSIGht. In GlobeSIGht, we use a Linux Virtual Server (LVS) cluster to avoid the bottleneck of network services throughout provided by the server, and use an Object-Based Storage (OBS) cluster to avoid the bottleneck of I/O throughout of the storage system for distributed spatial data. Spatial data is organized as spatial storage object stored in the object-based storage device, and the metadata server manages all the object-based storage devices and spatial storage objects to provide a spatial data shared storage pool as the backend storage of the LVS cluster. Furthermore, by using plug-in technology, GlobeSIGht has integrated many relevant application systems such as 2D geographic information system, 3D geographic information system, multimedia application subsystem, massive MODIS remote sensing images management and dispensing online system.
