This parameter can be used to change the visual display of maps. It is possible to reduce the amount of map information, and thereby display the map larger.

Example:
A map is to be printed in the size 59.4 x 42cm (A2) with a “vector_scale=2” factor. Information is therefore called up which would be displayed as standard on a map of size 29.7 x 21cm (A4), but with a background which corresponds to size 59.4 x 42cm (A2).
