Paper Abstract

Starting from analyzing the restriction of spatial object index of database, based on the requirement and theoretical research of Spatial Information Multi-grid (SIMG) under Grid Computing environment, the authors put forward a solution to grid index for grid database. Firstly, comparison has been made between spatial object index based on coarse grid and self-adaptive index. On the basis of this comparison a spatial object index algorithm based on self-adaptive grids is brought forward. Secondly, the general concept of self-adaptive grids, its data structure, realization of the algorithm and application in spatial query have been discussed in detail. Thirdly, the optimum level and value of self-adaptive grids in practical application have been figured out. And at last, its validity and feasibility have been verified.
