Spatial Grid Services for adaptive spatial query optimization
Spatial information sharing and integration has now become an important issue of Geographical Information Science (GIS).Web Service technologies provide a easy and standard way to share spatial resources over network,and grid technologies which aim at sharing resources such as data,storage,and computational powers can help the sharing go deeper.However,the dynamic characteristic of grid brings complexity to spatial query optimization which is more stressed in GIS domain because spatial operations are both CPU intensive and data intensive.To address this problem,a new grid framework is employed to provide standard spatial services which can also manage and report their state information to the coordinator which is responsible for distributed spatial query optimization.
