Data check and processing tools for national land change database based on FME
To solve the problem of time-consuming and laborious data modification in integrating the national land change survey data into the database,a set of automatic check and processing tools based on a feature manipulate engine(FME)was built.The tools could check the geometry errors and attribute errors of polygons and automatically process them in batch according to the requirements of national land change database construction.The tools were tested with the national land change survey data of a county in Guangdong Province in 2022.The results show that the tools can automatically identify and process errors in bath,reduce the workload of manual polygon modification,and greatly improve the efficiency of database construction.
