Fuzzy SOFM-GIS space cluster model and its application analysis

The fuzzy SOFM-GIS space cluster model is a new cluster model based on theory of fuzzy, self-organizing feature map network and GIS. Fuzzy theory is used to solve uncertain problems. GIS is of strong space analysis ability. Self-organizing feature map network are of ability of strong self-learned, self-adaptive, error-permissive ability and model identification. The model is adapted to solve cluster problem of multiple objects under multi-index condition in fuzzy or uncertain systems and these systems are of space characteristic. It is used to classify the red soil resource in Zhejiang province. The results show that the model is stable and reliable.
