土地利用更新调查中SPOT5影像正射纠正方法的应用研究
Study on the application of SPOT5 satellite image orthophoto correction to the updating investigation of land use
【摘要】 本文结合3S技术在土地利用更新调查中的应用实践,以云南省红河州石屏县为研究区,探讨了高分辨率SPOT5卫星影像正射纠正的应用方法,对影像纠正精度进行了检验和分析。研究表明,严格按照有关技术规定要求对SPOT5 2.5m影像进行正射纠正,其精度可以满足1∶1万土地利用更新调查的精度要求。
【Abstract】 Related to the application of the 3S technology in the land use updating investigation in Shiping County,Yunnan Province,the application method about the high resolution SPOT5 satellite image orthophoto correction was discussed and the correction precision was tested and analyzed.According to the related technical stipulation,the author corrected SPOT5 2.5 m orthophoto image,which could satisfy 1∶10000 land use updating investigation precision request.
