1∶10000比例尺多源数据的修测更新入库

1∶10000 Scale Multi-source Data Revision and Update into the Database

对已有1∶10 000比例尺多源数据(格式为GDB、DEM、DGN)分析,通过编写FME模板完成原始数据库(GDB)-修测矢量(DLG)-更新成果数据库(MDB)三者之间的无缝转换,以及成果数据库MDB的质量检查,实现多源数据融合修测更新入库。整个实现过程高效率、高质量,具有良好的经济效益,解决了常规数据库修测更新过程中,必须配备专门的数据平台、操作交互性差及效率低的问题。

After analyzing the 1∶10 000 scale multi-source data(the format is GDB, DEM, DGN), through writing FME template, we completed the seamless transformation among the original database GDB, revision vector DLG and update database MDB, and the quality check of MDB,which realized multi-source data revision, update into the database. The whole process is of high efficiency, high quality and good economic benefit, which solves the problems of special data platform, poor operation interaction and low efficiency in the process of routine database revision and update.
