摘　　要：现有地理信息分类方法均未将地理信息安全利用等级纳入分类体系之中,无法有效解决不同网络环境下地理信息的有效衔接与高效利用问题。针对不同网络环境下地理信息数据内容及信息安全的差异化要求,提出了一种基于要素分类和安全利用分类的地理信息分类方法,从图层、要素和属性3个层面对地理信息进行集中统一管理,丰富了地理信息分类标准。All the existing geographical information classification methods do not include the geographical information security utilization level,and it is impossible to effectively solve the problem of efficient convergence and utilization of geographical information in different network environments.Aiming at the difference of geographical information data content and information security in different network,we proposed a geographical information classification method based on factor classification and security utilization classification,which could achieve unified management of geographical information from the three layers of layer,element and attribute,and enrich the geographical information classification standards.
