Formation of a mathematical basis is carried out in dialog Mathematical grid making. In the process of formation, at first the objects of the mathematical basis of the original map are automatically deleted, then the automatic creation of the objects of the mathematical basis (horizontal and vertical coordinate lines of the rectangular grid, points of crossing coordinate grid, grid ticks of parallels and meridians, the central cross) is performed. The content of created objects of the mathematical basis depends on scale of a formed map.
