To ensure the lunar lander landing safely, and execute the expected scientific experiments smoothly, a new terrain simulation method is proposed in this paper, which can build a terrain model of Sinus Iridum with a high resolution of better than 1 meter. The terrain surface trend is fitted from a low-resolution terrain with genetic programming (GP) and genetic algorithm (GA). A high resolution terrain with a resolution up to 1 cm in a 10 m×10 m region is built by applying the distribution laws and the models of craters and rocks in Sinus Iridum region. This method can be used to analyze the landing safety of lunar lander and decide a safe landing site by simulating precisely the real terrain characters.
