资源1号02D卫星参数见下表
表1
ZY1 02D高光谱数据看起来就像小号的GF5 AHSI,它的传感器其实也叫AHSI,不过将GF5的330个波段减少到了166个,其中VN
波段范围76个,SW波段范围90个。空间分辨率仍然是30m。
在RSD平台加载ZY1 02D AHSI数据与GF5 AHSI类似,图1。
图1 ZY1 02D AHSI 高光谱数据
资源1号02D卫星多光谱数据有8个10m空间分辨率的MSS波段和一个2.5m的PAN,特点是扫面范围有点的大,115km的幅宽PAN正射后范围可达5W*6W(30亿)像元。全色数据在RSD
正射校正加载后见图2。
图2 ZY1 02D 全色2.5m分辨率数据。
多光谱数据见图3.。看起来同一个数据集的多光谱数据和全色数据存在一些一致性问题,不过没关系,可以纠正。
图3 ZY1 02D 多光谱10m分辨率数据。
融合后效果见图4.。
图4 LiIFT 融合的ZY1 02D 2.5m多光谱
多光谱数据就是大一些,处理起来慢了一点。不过问题不大。
