| Abstract: | This paper has studied service architecture of multi source remote sensing(RS) data's distributed service system based on SVM.First,this paper has set up a solid index mechanism of Pyramid,Block,Layer,Epoch according to the properties of RS data and analyzed the organization and storage of multi source RS data on background.Secondly,this paper has designed parallel processes aiming at the background server's service functions.Moreover,these processes have been tested and analyzed for the improvement of parallel computer cluster performance as background server based on SVM.Also,this perofrmance improvement of the parallel PCs background server has been demonstrated. |
| Keywords: | multi source remote sensiug data parallel computer cluster service architecture solid index mechanism |
