Pyramid Tree Cluster- A new high-dimensional data indexing method presents a new and effective method for high dimensional spatial data indexing- Pyramid clustering tree it first on the uneven distribution of data clustering, and then results clustering implementation pyramid segmentation and storage, thereby establishing an effective index structure paper presents several query clustering algorithm pyramid tree proved: when dealing with the uneven distribution of data, both in the clustering tree pyramid page visits, or in the total of occupied CPU time is better than the pyramid tree.
