Default zoom Mapping module


where can I change the level zoom default of the map ?

What are the files, I should modify ?
Many thanks in advance for your help,

You mean for the map in every instance, for whenever you start mapping a resource?

yes I mean for each item with a map resource, my zoom is much too close from the earth.

I would like the all country to appear to see where is the marker in the country.

I would like the public view of the map being larger.
