This study focuses on spatial metaphor expression and analysis of hierarchy data with the help of map metaphor. We use classic cartographic methods synthetically to process the non-spatial data to realize the spatialization. This process makes abstract data concrete which can reduce cognitive load. In addition,it expands the extension of cartography. In terms of specific methods,we use the landscape metaphor to reflect data feature,and introduce LOD and Cartogram into map metaphor which is suitable for hierarchy data's structural characteristics. Comprehensive usage of above methods help highlight features of each layer of data and analyze data characteristics through the map. At last the validity of this method is verified by the real file hierarchy data. We conduct experiments to analyze file number distribution,large file location and file depth. The results show that our method can effectively express the hierarchical data and support some map analysis and data mining.
