Research on fusion method of multi-source level crossing road data in Tianditu based on FME
YU Lin
Abstract：To achieve efficient integration of multi-source at-grade road data,this article develops an automated model for merging and updating road data graphics and attributes based on the spatial data transformation processing system(FME).This model effectively addresses issues in at-grade road data such as geometric deviations,attribute inconsistencies,and topological errors,significantly shortening the work cycle and meeting the quality requirements for Tianditu data integration.As a public version of geographic information service shared data source,this model can use commercial cryptographic technology to ensure the integrity,security,and validity of the data.
