Hi,
I have set up the API so that it is possible to draw a polygon on the
map, exactly like in "MyMaps". I would now like to extract the
coordinates of any polygon drawn and use the coordinates in an SQL
query.

Is there a way to do this directly, i.e. can I access the array of
lat,lon coordinates and format them into an SQL query within a
javascript function?
if so - how do I access this array of coordinates?

Or do I need to go a more circuitous route, saving the output as KML
(as one would in the myMaps tool by clicking on 'view in Google
earth') then parse the KML to extract the points?
If I need to do it this route, how do I save the map in KML? I am
familliar with the syntax of KML and how to build it - lots of info on
this on the Web, but I cant figure out how to save the map created
with using my map display as KML.

My map display is at: http://eoinmaca.com/maps/mymap.html

Many thanks,

Fahad
