Google Maps Plugin – Filter tags via ajax



I am looking at have a static map on a page.

Over the top of it, list tags available that belong to the current map.

Also, I want to display other tags that are also associated with the posts on the local blog.

That would be achieved by AND íng the tags.

But in order for the user to choose the tag, they will need a legend to select available tags.

When they select a tag the map would have to ajax reload in the background.

That is my navigation question. Can it be achieved internally within the Google Maps plugin and ajax/jquery? or should I just reload the map on another page?

I believe, at the moment, if i can center lat long on the location then call a different tagged map, that would work. How do i specify the center lat long again?

Many thanks,
