Vector map is a multiscale map. The scale indicated in the map passport is used as the base scale when publishing the map. In a base scale the sizes of all conventional symbols, thicknesses of lines and height of titles (in millimeters) correspond to those indicated in symbol parameters. For maps, the territory of which is not limited by the frame, scale change is permissible. If the map contains too dense clusters of large conventional symbols, it is recommended to reduce the scale denominator in the passport. If the denominator is reduced from 100 000 to 10 000, the relative sizes of all symbols will decrease by 10 times.

The nomenclature of a sheet can not be edited for topographical maps of a standard division, because by its value the calculation of sheet coordinates is made. Coordinates of a sheet for this type of maps also are not a subject to editing.
