【摘要】：提出了一种基于自定义投影网格的多角度、多源遥感数据空间位置精确配准方法。以美国地球观测卫星(EOS)上搭载的多角度成像光谱辐射仪(MISR)L2级产品与中分辨率成像光谱仪(MODIS)L3级产品的空间位置精确配准为例,分析比较了软件ENVI、HEG、MRT及所提方法对两种产品进行投影变换时的数据处理能力。将欧洲空间局环境卫星ENVISAT的先进沿轨扫描辐射计(AATSR)数据与MISR L2级产品及MODIS L3级产品数据进行配准,对所提方法进行验证。所提方法解决了常用遥感软件不能直接将MISR L2级产品数据与其他遥感数据进行空间位置精确配准的问题,且对科学数据仅进行一次重采样,避免了反复重采样可能造成的信息损失。对于类似多角度遥感数据的空间位置精确配准,所提方法的基本思路和目标同样有效。
[Abstract]:A multi-angle and multi-source spatial location registration method for remote sensing data based on self-defined projection grid is proposed. Taking the multi-angle imaging spectral radiometer on board the United States Earth observation Satellite (EOS) as an example, the precise registration of the spatial position of the MISR-L2 product and the medium resolution imaging spectrometer / MODISN L3 product is taken as an example. This paper analyzes and compares the data processing ability of the software ENVIX HEGM MRT and the methods proposed in the projection transformation between the two products. The data of Advanced Orbital scanning Radiometer (AATSRS) of the European Space Agency (ENVISAT) environment satellite are registered with the data of MISR L2 and MODIS L3, and the proposed method is verified. The proposed method solves the problem that the MISR L2 product data can not be directly registered with other remote sensing data by using the common remote sensing software, and the scientific data can only be resampled once. The information loss caused by repeated resampling is avoided. The basic idea and target of the proposed method are also effective for the precise registration of spatial positions similar to multi-angle remote sensing data.
