第三次全国土地调查正射影像生产方案的探索——以景泰县为例

Exploratory on the orthography production for the 3th national land survey——Take Jingtai County as an example

文中以现势性高的北京2号与高分2号遥感数据为数据源,采用集群式遥感影像处理系统PixelGrid,充分合理利用已有DOM和DEM数据,探索满足第三次全国土地调查正射影像生产的方案。通过内外业精度检测的方式,验证该方案生产的正射影像满足调查要求,可用该方案生产非建成区正射影像的生产。

Taking the high-precision Beijing No.2 and Gaofen No.2 remote sensing data as the data source, the production program of the third national land survey orthophoto was explored using the cluster remote sensing image processing system PixelGrid and the existing DOM and DEM data. Through the method of internal and external precision detection, it was verified that the orthophoto produced by the scheme meet the survey requirements, and the production of orthophotos in non-built areas could be produced by this scheme.
