A Relation Model Based Spatial Grid Catalogue

Spatial Grid provides a well solution to effective sharing of geographically dispersed spatial data. Various distributed spatial task processing like query can be achieved upon it. To support task allocation in Spatial Grid, effective and reliable spatial grid catalogue should be developed since it provides resource distribution information. This paper proposes a novel relation model based spatial grid catalogue. Design and implementation details for constructing our proposed spatial grid catalogue are discussed. Practical experiments also reveal the relation model based spatial grid catalogue can effectively discover appropriate grid resources and help make better spatial task allocation.
