Topographic correction of HiRISE and CaSSIS images: Validation and application to color observations of Martian albedo features

The topographic correction of satellite images has to be applied both disentangle albedo features from illumination effects induced by local topography and perform spectrophotometric analyses planetary surfaces. This work focuses on the modeling removal surface brightness variations topography, referred as shading, high resolution Mars. Topographic shading can modeled through functions observation angles called disk functions. We consider four that are widely used in photometry: Lambert, Lommel-Seeliger, Akimov Minnaert test evaluate their performances removing High Resolution Imaging Science Experiment (HiRISE) Colour Surface System (CaSSIS) images. here validate our method, moreover, we report scientific applications single or multi-band datasets analyzing topographically corrected HiRISE colour observations Martian recurring slope lineae dust devil tracks, well CaSSIS panchromatic observations.
