摘要
以通过1∶2 000缩编1∶10 000地形数据更新试验为例,详细探讨了该方法的技术路线,工作流程,质量检查过程。对各要素层缩编进行了详细的分析,给出了制图综合的具体指标,为采用缩编方法更新1∶10 000基础数据提供参考。
Taking updating 1∶ 10 000 topographic data by downsizing 1∶ 2 000 data as an example,the paper discussed the method＇s technical route,workflow and quality control procedure.Downsizing layers for every element was analyzed in details,specific integrated indicators for mapping were given.That provided reference for updating 1∶ 10 000 basic data by downsizing method.
