[VHFcontesting] Grid map overlay for google maps

It sounds like you're looking for example programming to the Google Maps API
so you can display your own map in a web page with the Maidenhead grid
super-imposed on it. Or maybe I've completely missed the point, in which
case, never mind, nothing to see, move along...

I've never seen a programming example for the general case of drawing a grid
over a Google map that works at all different zoom levels. I'd love to see
such an example, too.

Here's an example of a single grid square drawn on a Google map that I
designed to show just one grid at a time in Washington state:

There may be some useful Javascript techniques in there for you to
plagiarize. Hope it helps! 

Another Google map tip: As a map user, you can get the lat-long at any point
with a right-click and "what's here?".  And there is a browser add-on to
display the lat-long at the mouse pointer while holding the Shift key. Both
are clunky, but at least you can find grid transitions.

Hi Guys,
I'm starting to do some planning that may or may not happen but I'm looking
for a link to a gridmap overlay onto Google maps. This will be used to zoom
in on potential locations.
Google has a terrain feature so you can also view elevation as well as
global views.
Any help would be appreciated.
