Research and verification of geographic entity data specification in Xining based on new basic surveying and mapping
In order to better promote the management and sharing of new basic surveying and mapping data in Xining and solve the increasingly prominent problems of traditional surveying and mapping in product forms,technical methods,management methods,and other aspects,this paper closely focused on the overall requirements of national new basic surveying and mapping construction.The paper transformed the original basic geographic information data constructed on a scale with"geographical elements"as the perspective and object into the geographic entity data constructed according to"entity granularity and spatial accuracy"with"geographic entity"as the perspective and object.It actively explored and carried out research to standardize the classification,measured content,spatial identity coding,and data organization of geographic entities,so as to better support the collection,processing,database construction,and application services of geographic entity data in Xining.
