【Abstract】 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.更多还原
