基于Virtuo-Zo和Geoway的DLG数据制作与质量控制研究

摘要

以青海省贵南县为例,基于全数字摄影测量系统Virtuo-Zo和数字制图软件Geoway,研究1∶10 000 DLG数据的制作技术,并在数据生产过程中总结质量控制措施,对国家基础地理信息数据的生产具有一定的借鉴和参考作用.%Taking Guinan County in Qinghai Province as an example,based on full digital photogrammetric system Virtuo-Zo and digital mapping software Geoway,the paper studies the production technology of 1 ∶ 10000 DLG data and the quality control in the data production process.It would play a reference role in the production of national basic geographic information data.
