Discussion on Orthoimage Production Approach of the Third Land Investigation in Hubei Province

结合湖北省点军区第三次国土调查(以下简称三调)正射影像的生产实践,介绍了湖北省点军区概况和基础资料情况;分别利用Easy-Sat和PCI GXL对三调遥感影像进行正射影像制作,并分析了两种正射影像制作方法的特点和差异性,提出了更适合湖北省三调正射影像制作的方法。

Combining with the production practice of orthoimages in the third land investigation of Dianjun District in Hubei Province, we introduced the general situation and basic data of Dianjun District, and described two approaches of orthoimage production based on Easy-Sat and PCI GXL.Then, we analyzed the features and differences of two approaches, and offered a production approach which was more suitable for the orthoimage production of the third land investigation in Hubei Province.
