    Determining density of regular grid for creating DTM using bicubic spline interpolation
    (Wydawnictwa AGH, 2019) Burak, Konstântin Omelânovič; Kovtun, Vitalij; Levitskij, Roman; Makovičuk, Mikola
    The article present the accuracy of DTM reproduction created by authors program of bicubic spline interpolation on the example of different categories of relief complexity. Correlations are established between the size of regular grid, category of relief complexity and a mean-square error of height finding. The graph is drawn showing the dependence of accuracy of point height finding from DTM, the size of regular grid and category of relief complexity.

    When calculating arrival times between multiple points the problem that can arise is the proper location these points one the map. Grid points for which calculations are to be done may form a regular, orthogonal grid or may be located at different, irregular densities. In this paper the algorithm for creating irregular grid points based on regular grid will be presented. Both representations will be analyzed and compared. It will be evaluated whether the points of such grids are representative points for a given problem.
