The terrestrial spatial modeling system which does filtering operation given and on the basis of the finite difference harmony of the point of the position where it adjoins and the method of being related

摘要

The terrestrial spatial model database (21) and the terrestrial spatial model database cooperating, to possess with the processor (22) which at least executes one noise filtering operation concerning the data which possesses the altitude which it is related to the point of position of husband it is possible terrestrial spatial modeling system (20). The at least one noise filtering operation can include the fact that central point vertical separation of husband is decided the point of the position where plural adjoins concerning the point (45) of each position, on the basis of the harmony of finite difference between altitude of the point of position of given and.
