Abstract: The cluster similarity of classical clustering methods（such as the classification method, hierarchical method, etc.） is determined by the distance between points. However, according to the distribution of spatial data, the change of data direction tends to produce the different classes clusters. The direction of space discrete points is in any direction. With the direction of triangular face expressing the direction of discrete points, it designs and implements the spatial clustering of discrete points in the direction algorithm in a certain direction change threshold. It designs a pyramid-shaped experimental data and successfully achieves the experimental data clustering by this algorithm. By the clustering algorithm, the actual measurement points of an open pit coal mine in Inner Mongolia are successfully clustering.
