High-precision and high-resolution topographic information for surface hazard analysis and landing site evaluation are vital for the success of any landing mission to planetary bodies. They are also essential for planetary science research. A LSGI research group led by Prof. Bo Wu has systematically researched planetary remote sensing over the past decade. They have advanced research and development in planetary mapping and remote sensing data analysis. A new integrated 3D mapping model has been developed for high-precision and high-resolution topographic mapping of the Moon and Mars, surpassing all existing technology, such as photogrammetry or laser altimetry. Novel deep learning approaches have also been developed for more automated and robust analysis of planetary remote sensing data. These developments led to a 'Gold Medal' and an 'R. Alekseev Award' for the PolyU team at the 44th International Exhibition of Inventions in Geneva in April 2016. The research article about multiple-source data integration for precision lunar topographic mapping was cited by Nature Index as 'a landmark paper on lunar topographic models' in an analysis of the research produced by universities in Hong Kong. The developments and results have been extensively used for landing site mapping and characterisation for China’s lunar and Mars landing missions.
