Abstract

Abstract: This paper presents a method of organizing and retrieving information of multidimensional and semantic geographic metadata.Firstly，the paper describes the semantic relationship among different geographic metadata with ontology.Then it encodes the hierarchical information in the ontology with dimensional hierarchical coding，and moreover it organizes and retrieves multidimensional data using X-tree.Finally，this paper provides a case to show the method is practical.

Key words: geographic metadata, geographic multidimensional semantic information, ontology, hierarchical coding, X-tree

摘要： 针对地理信息元数据的语义关联特性和多维特性，提出了一种组织地理信息的方法。基于本体论描述不同地理信息元数据之间的语义关联特性；在此基础上，通过维层次编码量化在本体中所描述的层次结构；通过X树组织和检索处理后的多维数据，最后给出应用实例，说明理论的可用性。

关键词: 地理信息元数据, 地理多维语义信息, 本体论, 层次编码, X树
