Method for basic geographic entity relationship data inspecting
One of the typical features that distinguishes basic geographic entity data from traditional sur-veying and mapping products is to use relationship tables,triples,and other forms to express entity rela-tionship data.However,the expression of relationship tables brings challenges to data quality inspec-tion of data due to the reasons that there are no intuitive graphical data.In order to meet the application requirements for real 3D China products and ensure the quality of basic geographic entity data,this pa-per puts forward a fast inspection method for the correctness and completeness of entity relationships of basic geographic entity based on FME software,and selects data of a pilot city in Fujian Province to conduct experimental verification.The results show that the method proposed in this paper can quickly and accurately complete the quality inspection of entity relationships.
