Improved Chandrayaan-1 M³ data: A northwest portion of the Aristarchus Plateau and contiguous maria

Shkuratov, Yu.; Surkov, Ye.; Ivanov, M. +5 more

We provide and test a method to obtain significant improvement of available Chandrayaan-1 M³ data. The advance is achieved using the Gaussian λ-convolution of spectra and Fourier filtration of images. The main result is imagery of the reflectance across different wavelengths as well as parameters of 1 µm and 2 µm absorption …

Automatic endmember bundle unmixing methodology for lunar regional area mineral mapping

Yin, Jihao; Huang, Chenyu; Luo, Xiaoyan +1 more

The mineral distribution on lunar surface can contribute to studying lunar evolution, while abundance quantification is still challenging. Unmixing on spectral reflectance data is an effective way for mineral resource explanation, especially in hardly accessible area. In regional area unmixing, some existing unmixing models mainly rely on spectral…
