基于关系链映射的“四实”数据空间化研究

Research on Spatialization of “Four Reals” Data Based on Relational Chain Mapping

“四实”数据是当前城市管理中针对人、房及单位等要素进行数据采集和管理的具有地理实体特征的新型基础测绘数据类型。本文针对表单“四实”数据,基于地理实体数据特征创新性提出地理关联实体概念,以“四实”数据多级属性信息建立关系链映射,实现“四实”数据空间化落点。广州市越秀区人民南社区“四实”数据空间化实践表明,基于关系链映射的地理关联实体构建能够有效实现“四实”数据空间化,为数据类型的空间化提供了规范的技术与方法。

The “Four Reals” data is a new type of basic surveying and mapping data with geographic entity characteristics for data collection and management of urban elements such as people,houses,and units in current urban management.In this paper,based on the form-based “Four Reals” data,the concept of geographically associated entity is proposed based on the innovative characteristics of its geographic entity data,and the relationship chain mapping is established with the multi-level attribute information of the “Four Reals” data to realize the spatial placement of the “Four Reals” data.The “Four Reals” data spatialization practice carried out by Renmin South Community of Yuexiu District,Guangzhou City shows that the construction of geographically related entities based on the relationship chain mapping method and the method of data spatialization can effectively realize the “Four Reals” data spatialization operation.The spatialization of data types provides standardized techniques and methods.
