【摘要】：提出了一種基于自定義投影網(wǎng)格的多角度、多源遙感數(shù)據(jù)空間位置精確配準(zhǔn)方法。以美國地球觀測衛(wèi)星(EOS)上搭載的多角度成像光譜輻射儀(MISR)L2級產(chǎn)品與中分辨率成像光譜儀(MODIS)L3級產(chǎn)品的空間位置精確配準(zhǔn)為例,分析比較了軟件ENVI、HEG、MRT及所提方法對兩種產(chǎn)品進(jìn)行投影變換時(shí)的數(shù)據(jù)處理能力。將歐洲空間局環(huán)境衛(wèi)星ENVISAT的先進(jìn)沿軌掃描輻射計(jì)(AATSR)數(shù)據(jù)與MISR L2級產(chǎn)品及MODIS L3級產(chǎn)品數(shù)據(jù)進(jìn)行配準(zhǔn),對所提方法進(jìn)行驗(yàn)證。所提方法解決了常用遙感軟件不能直接將MISR L2級產(chǎn)品數(shù)據(jù)與其他遙感數(shù)據(jù)進(jìn)行空間位置精確配準(zhǔn)的問題,且對科學(xué)數(shù)據(jù)僅進(jìn)行一次重采樣,避免了反復(fù)重采樣可能造成的信息損失。對于類似多角度遙感數(shù)據(jù)的空間位置精確配準(zhǔn),所提方法的基本思路和目標(biāo)同樣有效。
[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.
