摘要
本文通过对国家1︰5万DLG更新工程的生产实践,提出基于粗纠正卫星影像进行1︰5万DLG数据库"一体化"生产工艺流程的新思路,探索在没有精纠正卫星正射影像(RSDOM)的情况下,进行"一体化"更新作业,最后对影像及编辑的矢量数据成果进行精纠正的生产工艺。
In the process of state 1：50000 database update project, this paper proposed that a new idea for the 1：50000 DLG data integration produce base on rough corrective RSDOM. Under the situation of that haven＇t any correction of RSDOM, do the integrative update work, finally carry on the accurately corrective work for the image and vector data production.
