Raster-based method of spatial-clustering of spatial dots through shortest euclidean distance

GENG Xie-peng①,HU Peng②(①Wuhan Polytechnic University,Wuhan 430022,China;②School of Resource and Environment Science,Wuhan University,Wuhan 430079,China)  
Spatial-clustering analysis is an important spatial analysis method of GIS.With an analysis of vector-based method of spatial-clustering's disadvantage such as data-redundancy and lack of intuition,this paper investigates the algorithms of distance transform through Map Algebra.Then a new raster-based method of spatial-clustering of spatial dots through shortest Euclidean distance is proposed.It is proved by the example that it is an intuitionistic and good method.
