基础地理实体MA标识体系初探

Preliminary study on MA identification system of fundamental geo-entities

针对当前因基础地理实体标识码不统一、不持久导致的多源数据无法与其精准对接、数据资源无法高效流通的问题,该文在对比研究当前主流标识体系的基础上,设计了适用于新型基础测绘与实景三维建设的基础地理实体MA标识体系,涵盖实体编码、标识注册、标识解析及基于实体标识的应用服务等。研究与实验表明,基础地理实体MA标识码具备全球唯一、终生保持等特点,基础地理实体MA标识体系能够支撑构建基础地理实体的应用生态,未来可以从根本上解决多源数据关联共享的难题。

Fundamental geo-entity is the main data content of new fundamental surveying and mapping and 3Dreal scene,and is the basic unit to connect economic and social data and business data of various departments.In view of the current problems that multi-source data cannot be accurately docked with it and data resources cannot be efficiently circulated due to the non-uniform and non-persistent identification codes of fundamental geoentity,the thesis designs a fundamental geo-entity MA identifier applicable to new fundamental surveying and mapping and 3Dreal scene based on the comparison and research of current mainstream identification systems,covering entity coding,identification registration,identification resolution and entity identification-based application services based on entity identity.The research and experiments show that fundamental geo-entity MA identifier has the characteristics of global uniqueness and lifelong retention.Fundamental geo-entity MA identification system can support the construction of the application ecology of fundamental geo-entity,and can finally solve the problem of multi-source data association and sharing in the future.
