[AccessD] OT Google maps

Hi All:

This definitely OT but the list is such a talented group I pose this
computer programming question.
 
There are a number of agencies that sell lat and long cross-references to
zip and postal codes and those can be used roughly positioning a 'marker' on
a Google maps page. If you only need a few locations on a map is there a
quicker way than zooming, clicking, capturing the mouse position and then
manually entering the results for each marker into the page script? If there
are only a couple of markers it is definitely the best way but if there are
say 20+ required are there any short-cuts?
