The paper first to carry on three clustering divisions to the spatial objects using the improved TGSOM algorithm, and obtains a series of similar nodes which contain the spatial objects of which have the same quantity and the same area on the whole, as well as a few noise spots which do not belong to any similar nodes, and then constitutes the dendritic structure after removing the noise spots; afterwards, optimize for the dendritic structure using the mixed structure based on the quad-division and the R* tree, which has eliminated the overlapping and coverage factors to the nodes, and has improved the retrieval efficiency of the mass data; Finally it has proved the validity and accuracy of the method through the experiment.
