摘要
以资源三号分辨率为2.1 m的卫星影像及高分一号分辨率为2 m的卫星影像为例,论述了2 m级分辨率卫星影像在1∶10000基础地理信息数据更新中的应用,并针对2 m级分辨率卫星影像在应用过程中的技术要点进行了研究。经实际生产论证,资源三号、高分一号等2 m级分辨率卫星影像经过必要的控制手段,能够满足1∶10000基础地理信息数据更新的精度要求。
Taking the satellite image of ZY-3 with a resolution of 2.1 m and the satellite image of GF-1 with a resolution of 2 m as examples,the application of the satellite image with a resolution of 2 m in the update of basic geographic information data of 1∶10000 is discussed.And the production research is carried out on the technical points of the 2 m resolution satellite image in the application process.According to actual production demonstration,2 m resolution satellite images such as ZY-3 and GF-1 can meet the accuracy requirements of 1∶10000 basic geographic information data update through necessary control methods.
