SDPG: Spatial Data Processing Grid

Spatial applications will gain high complexity as the volume of spatialdata increases rapidly. A suitable data processing and computinginfrastructure for spatial applications needs to be established. Overthe past decade, grid has become a powerful computing environment fordata intensive and computing intensive applications. Integrating gridcomputing with spatial data processing technology, the authors designed aspatial data processing grid (called SDPG) to address the relatedproblems. Requirements of spatial applications are examined and thearchitecture of SDPG is described in this paper. Key technologies forimplementing SDPG are discussed with emphasis.
