Abstract
A system including a module for acquiring source bases of terrain data corresponding to an area of a terrain, divided into a plurality of cells; each source base containing, for each cell, an elevation, a module for transposing each source base into a respective transposed base of terrain data corresponding to the area of terrain, divided according to a reference mesh into a plurality of transposed cells, each transposed base including, for each transposed cell, a transposed elevation, a module for evaluating a local consistency level, based on the comparison of the transposed elevation of the cell with the transposed elevation of the corresponding transposed cell of at least one other transposed base, and an assistance module configured to determine a navigation assistance datum for the aircraft, depending on the assessed local consistency level.
