Spatial clustering analysis is important method and study content of spatial analysis and spatial data mining. In Map Algebra, through establishing Raster square plane, by which Raster reference and distance square are corresponding, the shortest distance of Raster space is computed, and Raster distance transformation is realized. Based on Raster distance transformation, by extracting characteristic equidistant lines, the clustering process of simple points is discussed. And then, this method is applied to the case of all-kind objects, weighted distance and the space having obstacles. From the examples, it is proved the algorithm is simple and reasonable.
