In the cnversion production of fundamental geo-entity data using the fundamental geographic information elements are confronted with various formats,large amount of data,difficult semantic transla-tion,lack of 3D information and so on.A set of production process is designed to realize the rapid materalization production and application of fundamental geographic information elements in this paper.Through the application of ETL technology for data conversion,knowledge graph and geographic informa-tion system(GIS)spatial operation for semantic processing of entity relationship,multi-source elevation data for acquisition of fundamental geo-entity 3D information,it has achieved the rapid convert production and application of fundamental geo-entity data.The production process and technology have been proved to be feasible which meet the requirements of production accuracy and obtain fundamental geo-entity data more efficient,and can be applied to a variety of using scenarios.
