摘要
基于加快推进新型基础测绘体系建设,不断提升基础测绘支撑服务能力和水平的目的,以存量1∶500大比例尺DLG数据为基础,结合DOM、国土变更调查等参考数据,研究DLG转换为基础地理实体和专业类自然资源管理实体生产流程,通过广州市新型基础测绘珠江新城(新中轴)琶洲试验区实践,分析基础地理实体和自然资源实体生产转换的技术实现过程以及转换成效。
In order to accelerate the construction of a new fundamental surveying and mapping system and continuously improve the ability and level of basic surveying and mapping support services,based on the 1∶500 large scale DLG data and combined with reference data such as DOM and land change survey,the production process of DLG conversion into basic geographic entities and professional natural resource management entities was studied.Based on the practice of Pazhou Experimental Area of Guangzhou's new fundamental surveying and mapping practice,Zhujiang New City(New central axis),this paper analyzes the technological realization process and conversion effect of basic geographic entity and natural resource entity production.
