For elevation data, a regularized interpolation for resampling and an algorithm for extracting terrain roughness and slope with landing area plane fitting are presented.
针对高程数据，给出一种规则化插补的重采样方法和基于着陆区平面拟合的粗糙度与坡度提取算法。

Increasing arresting force and improving low-speed aero characteristics can increase allowable maximal landing mass with an enlarged envelope area, but changing glide slope Angle makes little effect.
