Yes the static Locations map provided by UNA... can that be zoomed in on and be more accurate?
Yes, it is possible to change the zoom level for this. But this is not a configurable parameter and you will have to edit the file manually
the text "zoom=7" - you can change it to lets say "zoom=12".
As to the accuracy - this totally depends on the location string provided. Google geocodes location on its own using the location string provided.
